# The Lady, The Shopkeeper And A Fake Note - Find the Loss

A lady buys goods worth Rs. 200 from a shop. (shopkeeper is selling the goods with zero profit).

The lady gives him Rs. 1000 note. The shopkeeper gets the change from the next shop and keeps Rs. 200 for himself and returns Rs. 800 to the lady.

Later the shopkeeper of the next shop comes with the Rs. 1000 note saying "duplicate" and takes his money back.

How much LOSS did the shopkeeper face?

The answers that people came up with were - Rs. 1000, Rs. 2000, Rs. 1800, Rs. 1200 and Rs. 800

If you are going to reply with an answer, please provide a detailed solution. Posted in: #Coffee Room

Since he sold 200rupees of goods and got original 200 from other shop keeper so there is no loss.

Next comes he gave 800 away to the lady who deserves.

But when the note is fake, he has to give back 1000. so I think answer is 1000.

My answer would be Rs. 1000 too.

Am I right here!!

Because the cost of item sold is considered separately.

I am considering sold Item value also . The table I given is clearly showing this.Ankita KatdareBecause the cost of item sold is considered separately.

I know explaining this orally is difficult that's why I calculated on totally math based.

However, like you showed in the chart; if we do not consider the transaction that happened before the lady entered the shop; the total loss is equal to Rs. 1000; as your table points.

Write an explanation please 😀SarathKumar ChandrasekaranMine :1200

Lady is +200, shopkeeper1 is with fake note (0 bucks) and -200 (value of goods).

Here, the main confusion is goods,

**if we replace goods by a 200 bucks note then the whole thing will be clear.**Lady exchanged her fake note: so lady got +1000

Shopkeeper2 is in no loss no profit : +-0

To equalize this shopkeeper1 must go into loss of total : -1000.

total loss-200(product price)+1000(given to neighbor shopkeeper)=1200.Kaustubh KatdareWrite an explanation please 😀

actual intake -- 1000 /- (lady had given fake currency and next shop has given 1000 in change)Ankita KatdareA lady buys goods worth Rs. 200 from a shop. (shopkeeper is selling the goods with zero profit).

The lady gives him Rs. 1000 note. The shopkeeper gets the change from the next shop and keeps Rs. 200 for himself and returns Rs. 800 to the lady.

Spend -- 1000/- lady (800/ - 200 goods), 1000/ - next shop

Total loss - intake - spend

= 1000/-

-CB

Correct me if I am wrong.

This question is bit twisted, so that's why some people are confused,Ankita KatdareA friend asked me this question, the other day -

A lady buys goods worth Rs. 200 from a shop. (shopkeeper is selling the goods with zero profit).

The lady gives him Rs. 1000 note. The shopkeeper gets the change from the next shop and keeps Rs. 200 for himself and returns Rs. 800 to the lady.

Later the shopkeeper of the next shop comes with the Rs. 1000 note saying "duplicate" and takes his money back.

How much LOSS did the shopkeeper face?

The answers that people came up with were - Rs. 1000, Rs. 2000, Rs. 1800, Rs. 1200 and Rs. 800

If you are going to reply with an answer, please provide a detailed solution.

So lets modify the question to make it simple:

- Shopkeeper of next shop gave Rs 1000 and then took back Rs 1000, so we can safely assume that he did
**nothing.** - Lady gave a fake note which has zero value, so we can assume that lady gave
**nothing.**

"

*A Lady buys goods worth Rs 200*and shopkeeper returns Rs 800"

So clearly the shopkeeper gave Lady

**200 (goods) + 800 (cash)**

And hence the answer is

**1000.**

Hope it clears all the doubts 😀

I am giving the answers with proper assumptions.

**First Answer - 1200**

Assumption Made- Shopkeeper returned 200 rs to the other shopkeeper.

Assumption Made

**Explanation-**

200 rs worth goods + 800 rs returned to lady (Real currency taken from another shopkeeper) + 200 rs returned to the first shopkeeper( assumption) = 1200 rs loss.

**Second Answer - 1000**

Assumption made- Shopkeeper did not return 200 rs to the other shopkeeper.

Assumption made

**Explanation -**

200 rs worth goods + 800 rs returned to lady (Real currency taken from another shopkeeper) = 1000 rs.

**Third Answer - 800**

Assumption made-Shopkeeper's goods are insured in case of any theft or fraud 😁 and he did not return the money to the other shopkeeper

Assumption made-

**Explanation -**

800 rs returned to lady (Real currency taken from another shopkeeper)= 800

I hope the above answers with proper assumptions will help.

Lets analyse the transaction from the instance the shopkeeper gets the change from the next shop !!!!!

Rs. 1000/- worth of change (genuine money) he brings and from that .....

Rs. 200/-.. shopkeeper keeps and it is his inflow of cash (A)

Rs. 800/-.. the Lady takes as change and is shopkeeper's outflow of cash (B)

Now comes the next door shop keeper and takes his genuine money back

Here Rs. 1000/- is shopkeeper's again outflow of cash (C)

So the net loss or outflow of cash is (B)+(C) which will be 800+1000 = 1800/-

Cheers

Asad 😀

-for 0 rupees he received from lady the shop keeper paid her 800rs

-he had to pay back the other shop keeper 1000rs

-cost of item is 200rs negates the 200rs he kept for himself

Very good moderator ..... you are closing in !!!durga1800 rs

-for 0 rupees he received from lady the shop keeper paid her 800rs

-he had to pay back the other shop keeper 1000rs

-cost of item is 200rs negates the 200rs he kept for himself

2) next shopkeeper has to return 1000rs to the second shopkeeper

3)200+1000 = 1200

ans: 1200

P.S the confusing factor here is the change the shopkeeper gave to the lady, the money the shopkeeper return back to the 2nd shopkeeper

The answer is INR 1000 only.Ankita KatdareA lot of people have confirmed the answer to be Rs. 1200.

Because the cost of item sold is considered separately.

Lady gives 1000 rs fake note. Receives goods rs 1000 (200 product+800 rs cash).

Shopkeeper: Gives 1000 rs fake note to other shop keeper and receives 1000 real cash.

He gives 200 product and 800 rs. Keeps 200 rs with himself.

Then he returns 1000 rs to other shopkeeper.

The point what you are missing here is you are not considering the 800 outflow to the lady as loss.IssueThe answer is INR 1000 only.

Lady gives 1000 rs fake note. Receives goods rs 1000 (200 product+800 rs cash).

Shopkeeper: Gives 1000 rs fake note to other shop keeper and receives 1000 real cash.

He gives 200 product and 800 rs. Keeps 200 rs with himself.

Then he returns 1000 rs to other shopkeeper.

Technically the lady gave zero money and took product worth 200 and change worth 800.

INR 200 as you agreed, shop keeper keeps for himself.

The neighbor shopkeeper returns fake note (value of which is zero) and takes genuine 1000 cash

So the net loss is 800 + 1000 = 1800

From lady's point of view the loss is 1000micheal johnLady profits 1000RS, so lose for shopkeeper is 1000RS great👍

But from shopkeeper's point of view the loss is 1800

Think in terms of inflow and outflow of genuine money and fake moneymicheal john1) shopkeeper gave the lady 200rs worth product

2) next shopkeeper has to return 1000rs to the second shopkeeper

3)200+1000 = 1200

ans: 1200

P.S the confusing factor here is the change the shopkeeper gave to the lady, the money the shopkeeper return back to the 2nd shopkeeper

You will get the answer

Genuine cash outflow is 800 as change and 1000 returned to neighbor shopkeeper

200 in his pocket negates the value of goods

So total loss for him will be 1800

When the shopkeeper gets change from the neighbor shopkeeper worth 1000 he gives 800 to lady (genuine change) and 200 he pockets. This 200 what he pockets is missing in your table.Anoop Kumar

Am I right here!!

So when neighbor shopkeeper returns fake note and takes real note that means the shopkeeper is facing a fresh loss of 1000 (genuine money)

So 800 change and 1000 fresh loss = 1800 loss

The shopkeeper 1 took 1000 rs (+1000)from shopkeeper 2 and returned it after sometime(-1000). Hence the transaction between them should not be considered.asadhlcThe point what you are missing here is you are not considering the 800 outflow to the lady as loss.

Technically the lady gave zero money and took product worth 200 and change worth 800.

INR 200 as you agreed, shop keeper keeps for himself.

The neighbor shopkeeper returns fake note (value of which is zero) and takes genuine 1000 cash

So the net loss is 800 + 1000 = 1800

The duplicate money is Rs.1000. Getting the duplicate one, the shopkeeper has given a Rs.200 worth product and a change of Rs.800. The money got from the next shopkeeper has been returned. So, it need not to be considered. Now, the total loss would be Rs.200+Rs.800=Rs.1000.

what is the right answer😕Ankita KatdareAll mixed answers. No one knows the correct solution it seems.

Many people have come up with correct answer - you need to be able to see it logically.Ankita KatdareAll mixed answers. No one knows the correct solution it seems.

**A. Keeping the two transactions separate makes for easy solution -**

- With lady, inflow is fake note, outflow is goods worth 200 n 800 cash, so net outflow is 1000, hence loss is 1000.
- With the other keeper, two deals happen -
- first inflow is real 1000, outflow fake note.
- second inflow is fake note, outflow real 1000.
- therefore, net transaction is 0. so no profit, no loss there.

**B. If u insist on taking transactions as it happened then here it goes -**

- inflow from lady, fake note.
- Went to other keeper, inflow is real 1000, outflow fake note.
- Came back to shop, gave lady goods worth 200 n real 800. So outflow in cash value so far is 1000 n inflow is 200 which is still left.
- Other keeper comes back, inflow is fake note, outflow real 1000. To give this 1000, first keeper uses 200 that was left (from above point) n HAS TO ADD 800 OF HIS OWN MONEY. so net outflow is 800.

So, the first keeper's loss is goods worth 200 plus 800 given to other keeper, total of 1000. Remember that the 800 given to the lady was not his own money, it was the other keepers money! (IN THIS TRANSACTION CASE).

Therefore, net loss is 1000.

Hope I could get my points across. Think it over, even play act it if u want to 😀

1. 800/- returned to the lady.

2. 1000/- returned to the second shopkeeper against fake note.

I recommend to re-create this situation live with your friend and see what it actual loss.

TIP: Shopkeeper 1 only took out 800/- from his money-box☕

What people fail to take into account is the 1000 Rs. inflow that first keeper gets while his outflow is 800 to lady n 1000 to keeper.

Net inflow = 1000.

Net outflow = 1800.

Cash loss = 800. (A)

Goods worth = 200. (B)

Total loss = A+B = 1000.

Kaustubh, you spoke about goods actual loss being 400 regarding goods; that is called as opportunity loss, the keeper losing the chance to sell the good to somebody else. BUT in this case, sale price is same as cost price so there is no opportunity loss. Anyway I know, you agree with 1000 😀

- Money has intrinsic value (it must represent the value of goods)

- Money is ONLY a medium of exchange

Play the same scenario with stones representing fake currency and gold coins representing actual currency. Then see what the second shopkeeper loses at the end of the day.

You are right. Poor thinking on my part. Net result is that the first shop keeper got a bad note and gave away Rs.200 in goods and Rs.800 in cash. The rest is irrelevant.IssueThe answer is INR 1000 only.

Lady gives 1000 rs fake note. Receives goods rs 1000 (200 product+800 rs cash).

Shopkeeper: Gives 1000 rs fake note to other shop keeper and receives 1000 real cash. He gives 200 product and 800 rs. Keeps 200 rs with himself.

Then he returns 1000 rs to other shopkeeper.

So he lost 200 rs of goods and 800 rs cash making a total of 1000 rs.

because, lady gave fake note that means she gave nothing

shopkeeper (1); took 1000 from shopkeeper (2). by giving fake note (zero)

shopkeeper (1) gave product worth 200 + 800 change (for fake 1000 note). so now in his hand 200

lady got 200+800=1000 (for a fake note)

later shopkeeper(2) came and asked 1000 back.

then shopkeeper (1) gave 200 (in his hand ) + 800 from his own money.

so that finally got loss 1800 ( 200 product + 800 change to lady + 800 to shopkeeper (2) from his own money)

as shopkeeper (1) gave 1000 but 200 in his hand is product fair .

and finally it correct answer (no doubt at all )

ur"s> MSN KRISHNA

200 of the goods he sold

1000 he will have to return to the next shopkeeper

and 800 which he returned to the lady

that is how the total comes to Rs 2000

Point 1: The goods that were given to the lady worth 200 ....

Point 2: The remaining amount given to the lady(assuming the fake note to be real one) ie., 800rs.and

Point 3: The fake note which remained with the shopkeeper....He cant add it to his account....

So 200+800+1000 makes a total of 2000rs loss to him......

Loss on sale of goods as the note was duplicate =Rs 200

After getting real 1000 change from other shopkeeper, he returns Rs 800 to the lady.

which is loss of Rs 800 but he has real Rs 200 by the time he gets to know the note is duplicate.

Thus profit of Rs 200 but as soon as he gets to knw from the other shopkeeper he has to pay him Rs 1000

Thus total loss

= 200+800-200(Real money that he was left with)+1000

Thus,Total Loss = Rs.1800

Did you guys tried solving this problem in real scenario using actual objects (let say real money). Do try it.

A lot of people are making the mistake of

**not considering REAL 1000 that the first keeper got**from the second keeper. He only uses 800 OF HIS OWN MONEY, so cash loss is only 800 n 200 loss of goods, so total is 1000.

Another way of looking at this is to consider inflow n outflow of each of the person involved in the case -

- total inflow is fake note from lady,
**real 1000 from other keeper.** - total outflow is goods worth 200 plus 800 cash to lady, 1000 cash to other keeper.
- Loss is inflow - outflow i.e. 1000 - (200+800+1000) = 1000.

1.Shopkeeper lost 1000rs because of fake note.

2.He lost 200rs because of flow of goods.

3.He lost another 800rs.(by giving a change of 800 for fake 1000).

So I think he lost 2000rs in total.

But another way would be-

shopkeeper gave Rs.800 to lady, she leaves.

Then the other shopkeeper comes(from whom change was borrowed) gives fake Rs.1000 note and his money back.

So, 1st shopkeeper gave Rs.800 to lady and Rs.1000 to other shopkeeper so

**loss is Rs.1800..!?**

Then what about the goods worth of 200rs that shopkeeper sold to the lady?It should also be considered as loss,isn't it?Dhananjay HarkareI agree with loss to be Rs.1000

But another way would be-

shopkeeper gave Rs.800 to lady, she leaves.

Then the other shopkeeper comes(from whom change was borrowed) gives fake Rs.1000 note and his money back.

So, 1st shopkeeper gave Rs.800 to lady and Rs.1000 to other shopkeeper soloss is Rs.1800..!?

The first keeper keeps the 200rs with him. That is why he had a loss of 1800rs since the cost of goods he sold was saved with him.

yes the cost of goods is loss, but 200rs saved by him makes it neutral.

"The first keeper keeps the 200rs with him. That is why he had a loss of 1800rs since the cost of goods he sold was saved with him.[/quote]"

I agree with that. All I am saying is please also consider real 1000 that first keeper got from the 2nd one. The transactions between the two keepers cancels each other out. There is an exchange of real 1000 for fake note n vice-versa. So there is no loss or profit for either of them.

@Sindhu Chowdary

Your first point that (1.Shopkeeper lost 1000rs because of fake note.) is erroneous because you fail to consider that first shopkeeper initially got real 1000. He just returns this 1000 back to 2nd keeper.

"The puzzle is confusing because the two transactions (with lady n with other keeper) are mixed. To solve it separate the two."

For better understanding consider this scenario, after the first keeper gets real 1000 from 2nd keeper, the lady suddenly decides not to buy anything n asks for her money. The keeper then gives her real 1000 (as the fake note is with 2nd keeper). Later, 2nd keeper comes in n gives fake note back n demands real 1000. What do u think the loss is in this case??

That's a superficial mathematical analysis. In real world, where money represents goods, the combined transaction implies that the good is consumed. And hence, it can't be neglected.Shyam_puzzleFor instance, if I give you real 1000 in exchange of fake note n later return fake note and take back real 1000, do you make any loss??

How is my example superficial? It is exactly as it happened in the puzzle, the two keepers exchanging real notes for the fake one. I suggested the example just to drive home the point that the first keeper does not incur loss when transacting with the second keeper.

Certainly money represents value and I have not neglected it any of my explanations.

Ok

So at the end first keeper returns 1000rs of second keeper and is having 200rs which is the cost of goods he sold. So the only extra thing he is having is the 1000rs fake note making loss=1000rs.

Real money is not something to play with at my stage, as I am a student.

But yes with my roommates we tried this scenario using imaginary money.

The second shopkeeper can be safely ignored. He got his money back that he gave the first. No loss/gain in that. All that happened is that the lady gave the first SK a fake 1K and got back Rs.800 cash and Rs.200 goods.

The first fellow is holding on to the fake note.

Saandeep SreerambatlaThe loss is 1000.

Since he sold 200rupees of goods and got original 200 from other shop keeper so there is no loss.

Next comes he gave 800 away to the lady who deserves.

But when the note is fake, he has to give back 1000. so I think answer is 1000.

Other than, go to actual local merchantAnoop Kumar

Am I right here!!

As I said earlier, try the example with stones representing fake currency and gold coins representing actual currency. Then you'll notice what you are neglecting.Shyam_puzzle@Anand Tamariya

Well, I have been advocating play acting the whole scenario as well for better understanding.

I have been very specific in my answer (1000) and hope my explanations were good enough. You have neither given out your answer nor pointed out what I have been neglecting. Please clarify.

Assuming I'm the shopkeeper. The lady gave me 1k stones. I got 1k gold coins from other shopkeeper in exchange of 1k stones. I gave lady the bread and 800 gold coins. Now I'm left with 200 gold coins.Shyam_puzzle@Anand Tamariya

I have been very specific in my answer (1000) and hope my explanations were good enough. You have neither given out your answer nor pointed out what I have been neglecting. Please clarify.

If other shopkeeper demands 1k gold coins now. I'll have to add 800 of my own gold coins to repay him. So isn't my loss 800+200+800+ bread worth of gold coins? However, if you note, now I'm left with 1k stones (which is the answer you arrived at).

Ankita KatdareA lady buys goods worth Rs. 200 from a shop. (shopkeeper is selling the goods with zero profit).

"If other shopkeeper demands 1k gold coins now. I'll have to add 800 of my own gold coins to repay him. So isn't my loss 800+200+800+ bread worth of gold coins? However, if you note, now I'm left with 1k stones (which is the answer you arrived at).[/quote]"

As you can see Anand, you only had to put 800 gold coins of your own, hence your loss is 800 + bread which is worth 200 gold coins, thus total loss being 1000 gold coins. Of course you are going to be left with 1k stones which is fake note in this puzzle.

But after this computation I agree its 800 cash loss and 200 worth of Goods loss for Shopkeeper. (SK1)

Red in the table indicates fake note, Blue indicates Real money

Adding / removing balance 5000 just for cash flow movement

What you (and a lot of us) missed previously was the 1000 (in blue) inflow that shopkeeper1 gets from shopkeeper.

@Subhanshi

You miss that shopkeeper 1 ALSO RECEIVED 1000 from shopkeeper 2. Hence his loss is 1000 only.

let see care fully

Now the soap keeper have 200 rs

he add 800 rupees more to the 200 rs and give the soap keeper.

so the total loss is 1000 rupees.

r u got this one.

(shopkeeper selling the goods with zero profit) lady gives 1000rs note. shopkeeper gets change from next shop & keeps 200 for him and returns Rs.800 to lady. shopkeeper of next shop comes with 1000rs note saying duplicate & takes his money back. How much LOSS did shopkeeper face

I calculated and got the result as 1000 but still need clarification. Please provide

Explanation 1 (cash counter perspective) - End of the day all u have to see is the fake note sitting at the counter is invalid and that 1000 rs fake note is the loss since the good is sold with no profit.

Explanation 2 - (who lost and who gained) For those with any other answer pls try and think this way. If the shop keeper lost 1200 or 1800 or 2000 or any amount then the involving partys should have gained that same amount. The customer gave in 0(1000fake note) and got back 200 goods and 800 change so he gained 1000, the neighbor gave in 1000 real not for a fake note and again gave his fake note and got back his 1000 , so neighbor gained 0. so the gain for opposing partys are 1000.

Explanation 3 - (Accounts perspective) - Profit and loss is calculated on the basis of what u had and what u have , its called opening and closing balance.If the customer started with 1000 cash and 200 stock as opening balance at end of the day he would have 200 cash and 0 stock has closing balance .

"If" Opening balance is - 1000 cash and 200 stock. Then closing balance would be 200 cash and 0 stock si he had 1200 opening and just 200 closing, 1200-200 = 1000.

Hope this settles it 😀

He gave 1000 rs to neighbor which he taken from him. But he gave 200(product price) + 800 (Cash) to lady so total lose is rs 1000SarathKumar Chandrasekarantotal loss-200(product price)+1000(given to neighbor shopkeeper)=1200.

which 1000 rupees he paid to other shop keeper that 1000rs he taken from that shoo keeper only. So he taken 1000 pay back 1000= 0durga1800 rs

-for 0 rupees he received from lady the shop keeper paid her 800rs

-he had to pay back the other shop keeper 1000rs

-cost of item is 200rs negates the 200rs he kept for himself

Other side gave 200(goods) +800 ( Cash) so total loss is 1000

2. then he got 1000 from next shop and gave = 800 change to the guy=800 spent (So far he has spent 200 things plus 800 change, so 1000)

3. of the thousand he got from next shop 200 balance is still with shop keeper as he gave only 800 change to the guy!

4. now next shop guy comes and takes back from the shop keeper=800 (own money) + 200 balance of the money he had

So the loss is 200(things)+800(change)+800(extra he paid) which is 1800!

OK forget about the change he taken from other shop keeper. Suppose he taken 1000rs from other shop keeper and return back when he came to him. Now come to other side lady gave him 1000( duplicate) he gave goods ( 200rs) and balance 800 (cash) total 200+800= 1000 so he loss 1000rs onlyvenkataramanan babu1. shop keeper gave 200 worth things = 200 spent

2. then he got 1000 from next shop and gave = 800 change to the guy=800 spent (So far he has spent 200 things plus 800 change, so 1000)

3. of the thousand he got from next shop 200 balance is still with shop keeper as he gave only 800 change to the guy!

So the loss is 200(things)+800(change)+800(extra he paid) which is 1800!

OK only lady got profit 1000rs(200rs goods+ 800) and same 1000rs loss by shop keeper . After that nobody have any profit and nobody have loss. Other shop keeper give 1000rs change and kept duplicate note with him when he found its duplicate he came to shops keeper. He gave duplicate note to shopkeeper and get his 1000 back. So now other shopkeeper have his 1000 which he gave. Now he is in no profit no loss. Now the duplicate note with the main shopkeeper and he gave 200rs goods + 800 cash to lady so he loss only 1000venkataramanan babu1. shop keeper gave 200 worth things = 200 spent

2. then he got 1000 from next shop and gave = 800 change to the guy=800 spent (So far he has spent 200 things plus 800 change, so 1000)

3. of the thousand he got from next shop 200 balance is still with shop keeper as he gave only 800 change to the guy!

4. now next shop guy comes and takes back from the shop keeper=800 (own money) + 200 balance of the money he had

So the loss is 200(things)+800(change)+800(extra he paid) which is 1800!

Here is my perspective.

Lets assume that the sk1 initially has 5000 in his shop and a single good worth rs.200. So net worth of sk1 is 5200.

Now a lady comes and purchases that single good worth Rs.200 and pays him with fake currency. The sk1 gives it to next sk2 (bcoz all the 5000 he has is Rs.1000 X 5 denominations) and gets Rs.1000. He gives the change of Rs.800 to the lady and the good and keeps 200 with him. Which means now the good had been replaced with money Rs.200. now the net worth of sk1 is 5200. No profit/loss situation.

Later sk2 comes and claims his money back as he found that was a fake currency. So now the sk1's account (networth) becomes 4200. So the net loss is Rs.1000

i.e., 5200 - 4200 = 1000.

One more perspective is that if we assume cash and goods are different then the value is 5000 cash plus one good worth rs.200. SO net loss is 800 without including the goods loss.

The Shopkeeper has given Rs 200/- worth goods to lady. So Loss Rs 200

then Rs 1000 is given to another Shopkeeper, hence Rs1000+200= Rs 1200/-

and Rs 800/- returned to lady Hence,

Total loss is Rs 1000+ Rs 200+ Rs 800 = Rs 2000/-

He retuned same 1000 rs back to another shopkeeper which he taken from him. So loss only 1000(200 goods+ 800 cash to lady)Prasanna PapalkarThe Answer is Rs 2000/-

The Shopkeeper has given Rs 200/- worth goods to lady. So Loss Rs 200

then Rs 1000 is given to another Shopkeeper, hence Rs1000+200= Rs 1200/-

and Rs 800/- returned to lady Hence,

Total loss is Rs 1000+ Rs 200+ Rs 800 = Rs 2000/-

Think of him not as a shopkeeper, but a person standing on a street selling a Rs. 200 worth watch and that is all he has in his pocket.

So here is the simple scenario:

The lady is a passerby customer

SK1 is person selling Rs.200 watch

SK2 is another person with a Rs.1000 change of Rs.200 x 5

1. SK1 owns Rs.200 worth of watch (so he has Rs.200 in his pocket)

2. He gives it to Lady and so he is Rs.200 short

3. Lady gives him Rs.1000, SK1 takes it to SK2 (note that he has not touched his pocket, nothing in, nothing out), brings back Rs.200 * 5, gives Rs.800 to lady and puts Rs.200 in his pocket. So he has Rs.200 back in his pocket. (no loss yet, he has what he started with).

4. SK2 comes back and asks for Rs.1000.

5. SK1 gives him Rs.200 from his pocket and additional Rs.800 he has to get from his ATM.

6. He loses his Rs.200 from his pocket and additional Rs.800 so Rs.1000 is his total loss.

Input = Output.

SK2 has no profit no loss (he gets his $1000 back)

Lady gets $1000 ($200 watch and $800 cash).

So there is only net gain of $1000 to lady (goods and cash). This must come at a loss for SK1.

Folks who think $1800 are wrong because $ 800 SK1 is giving away to lady is not from his pocket, but what he got from SK2, which he ends up returning to SK2 anyways. You guys are counting $800 twice.

PS: It is not always necessary that majority is always correct, but for the lack of knowledge of the question creator - that's our best bet.

IAnkita KatdareA friend asked me this question, the other day -

A lady buys goods worth Rs. 200 from a shop. (shopkeeper is selling the goods with zero profit).

The lady gives him Rs. 1000 note. The shopkeeper gets the change from the next shop and keeps Rs. 200 for himself and returns Rs. 800 to the lady.

Later the shopkeeper of the next shop comes with the Rs. 1000 note saying "duplicate" and takes his money back.

How much LOSS did the shopkeeper face?

Even at first time i just thought it would be 1800 1200 but my ans is 1000 bcaz at first time shopkeeper initially having 200 Rs(goods) and finally he is having 200(cash) . Initially that lady has 0 but finally she got (200 worth goods + 800 as change) dont touch this part also and the sK1 receiving 1000 from SK2. he has return the money to him he is having (200 SK1 + 800(he has to put )) he has to give .so its 1000

The shopkeeper faced a loss of rs1800.Saandeep SreerambatlaThe loss is 1000.

Since he sold 200rupees of goods and got original 200 from other shop keeper so there is no loss.

Next comes he gave 800 away to the lady who deserves.

But when the note is fake, he has to give back 1000. so I think answer is 1000.

He had to return rs1000(original) to the other shopkeeper. He returned rs800(original) to the customer and gave items of rs200.

1000+800+200 = 2000

but her had rs200(original) with him for the product he sold.

So, total loss incurred by him - 2000-200=1800

He had to return rs1000(original) to the other shopkeeper. He returned rs800(original) to the customer and gave items of rs200.

1000+800+200 = 2000

but her had rs200(original) with him for the product he sold.

So, total loss incurred by him - 2000-200=1800

The shopkeeper faced a loss of rs1800.Ankita KatdareUnfortunately we don't have a final answer. Those who say the answer is 1000 or 1200, I fear, are making some unknown assumptions.

Correct me if I am wrong.

He had to return rs1000(original) to the other shopkeeper. He returned rs800(original) to the customer and gave items of rs200.

1000+800+200 = 2000

but her had rs200(original) with him for the product he sold.

So, total loss incurred by him - 2000-200=1800

If you give value to the duplicate note, The Lost would be Rs.2000/-.

If you don't give value to the duplicate note, The Lost would be Rs.1000/-.

Please correct me if I am wrong!!!!!

If you give value to the duplicate note, The Lost would be Rs.2000/-.

If you don't give value to the duplicate note, The Lost would be Rs.1000/-.

Please correct me if I am wrong!!!!![/QUOTE]

Value wont be given to the duplicate note. But he had to pay rs 1000 to the next shopkeeper from his own pocket and he also had to give rs800 to the lady.

Loss=C.P-S.P

=200(for goods)+1000(to other shopkeeper)-0(since the money was fake)

=1200

mel-jonesAnwser is 1000 (I own a shop and attend cash tills).

Explanation 1 (cash counter perspective) - End of the day all u have to see is the fake note sitting at the counter is invalid and that 1000 rs fake note is the loss since the good is sold with no profit.

Explanation 2 - (who lost and who gained) For those with any other answer pls try and think this way. If the shop keeper lost 1200 or 1800 or 2000 or any amount then the involving partys should have gained that same amount. The customer gave in 0(1000fake note) and got back 200 goods and 800 change so he gained 1000, the neighbor gave in 1000 real not for a fake note and again gave his fake note and got back his 1000 , so neighbor gained 0. so the gain for opposing partys are 1000.

Explanation 3 - (Accounts perspective) - Profit and loss is calculated on the basis of what u had and what u have , its called opening and closing balance.If the customer started with 1000 cash and 200 stock as opening balance at end of the day he would have 200 cash and 0 stock has closing balance .

"If" Opening balance is - 1000 cash and 200 stock. Then closing balance would be 200 cash and 0 stock si he had 1200 opening and just 200 closing, 1200-200 = 1000.

Hope this settles it 😀

Leave all the stuff from the beginning of the question just carry on from where the second shop keeper came and return back the fake note and here qestion fallows.

How much did the shopkeeper face ?

Answer is 0 Loss because because he gave the fake not and taken back the change he given.

Vamshi you are right about no loss in the interaction between the shopkeepers. The loss suffered by the first keeper is with the lady to whom he gives money as well as goods, net loss being 1000.vamshi krishanHai all dont simply go for math to solve this question just think, in the question it is said that to explain your answer. And never said to choose from the numbers given.

Why don't you read through all the answers? Some of them have explained it beautifully. Especially Mel-jones.

The answer must be

Rs 200 cash to purchase the good + Rs 800 given to lady

+ Rs 1000 - to Next shop keeper + and RS 200 good

So total loss would be RS 2200

1) Just Assume shop keeper doesn't have any money, he just had 200 rs worth goods.

2) Lady gave him 1000 rs fake note so it's value is 0.

3) So now he had 200 rs goods + 0 = 200.

4) Next shop keeper gave him 1000 rs.

5) So now he had 200 rs goods+0+1000.

6) And she took 200 rs goods + 800 rs money = 1000 rs.

7) Now he had only 200 rs (200 +0+ 1000 -200 -800).

8) And he has to give 1000 to next shop keeper so, 200 - 1000 = -800.

9) Now he had -800 rs,-200 rs goods and 0 (i.e., fake note)= -1000.

10) So his loss is 1000.

The lady gave a fake note of Rs.1000. Its actual worth is Rs.0. But she bought goods for Rs.200 and got Rs.800 as change. So the shopkeeper lost Rs.800 as cash and Rs.200 as goods. So he totally lost Rs.1000 to the lady. In between, he bought change from the next shop for the fake 1000 rupees note. In that change, he gave Rs.800 to the lady as we seen earlier. So now the shopkeeper has just Rs.200 with him(he got this for that goods sale). Now the second shopkeeper demands Rs.1000 from the first shopkeeper exclaiming that its a fake note. So the first shopkeeper gave Rs.1000 to the second. So he lost Rs.1000 to the second shopkeeper. Totally Rs.2000 is the loss incurred by the shopkeeper.Ankita KatdareA friend asked me this question, the other day -

Assuming the shopkeeper (SK1) has Rs.0 in his draw.

The lady show up with a fake note of Rs.1000 and buys a product worth 200.

Since the shopkeeper has no money with him, he takes the fake note to the next shopkeeper (SK2) and and buys change for Rs. 1000.

He pays Rs. 800 back to the lady.

Now he has Rs.200 (original notes) with him, he thinks he has regained his initial investment.

When the SK2 walks in with the fake note and asks him to change it, SK1 who has 200 with him now has take out 800 from his pocket so that he can give Rs.1000 to the SK 2.

So now he has given only 800 (from his pocket)+200 (value of the goods). hence the net loss is 1000.

Note: people get confused when they consider both 200(value of the goods) and the 200 which he had with him for a while after selling the shop as loss. only one entity can be considered.

Loss is 2000rs because shopkeeper has given 800+200(goods) and he also have to pay 1000 to other shopkeeper

lady come with bare hands (fake 1000)

shopkeeper gave 200 worth goods -> 200 loss

shopkeeper gave 800 Rs. to her -> 800 loss

shopkeeper gave 1000 Rs instead

fake note to sk.2 -> 1000 loss

total -> 2000 loss

😀 😀 😉 😁

The lady who confused the shopkeeper + 6 pages peoples = is...,😎

and her name is Ankita Katdare 😁😛😛😁😁

shopkeeper took 1000rs change and kept 200 and returned 800

later for next shopkeeper he has to return 1000 so he gave the 200 change+ 800 from his own money

so total 1800+ 200 products cost

2000

then where is the change 800 he has given to that ladymicheal john1) shopkeeper gave the lady 200rs worth product

2) next shopkeeper has to return 1000rs to the second shopkeeper

3)200+1000 = 1200

ans: 1200

P.S the confusing factor here is the change the shopkeeper gave to the lady, the money the shopkeeper return back to the 2nd shopkeeper

then where is the products cost he lossedmsn krishnaans; 1800

because, lady gave fake note that means she gave nothing

shopkeeper (1); took 1000 from shopkeeper (2). by giving fake note (zero)

shopkeeper (1) gave product worth 200 + 800 change (for fake 1000 note). so now in his hand 200

lady got 200+800=1000 (for a fake note)

later shopkeeper(2) came and asked 1000 back.

then shopkeeper (1) gave 200 (in his hand ) + 800 from his own money.

so that finally got loss 1800 ( 200 product + 800 change to lady + 800 to shopkeeper (2) from his own money)

as shopkeeper (1) gave 1000 but 200 in his hand is product fair .

and finally it correct answer (no doubt at all )

ur"s> MSN KRISHNA

he gave 200rs worth products so 800+200 there he lost 1000 and later he gave 1000 back total 2000

leave all that stuff.... he has given lady a 200+800=1000. that's it that is the final loss.. shopkeeper dint lose nothn than that. the nxt shop keeper has given change of 1000 and taken back the same 1000 so no loss at this side... so my ans is 1000 only think once its clr.Ankita KatdareA lot of people have confirmed the answer to be Rs. 1200.

Because the cost of item sold is considered separately.

Shopkeeper 1 is at a loss of Rs.1000

1000 for fake

800 bucks for the change

200 bucks the product worth

1000 for fake

800 bucks for the change

200 bucks the product worth

So 1000 is the net lose......

Kaustubh KatdareThe only way to arrive at a correct answer for this puzzle is to declare the assumptions. Otherwise we all will keep getting different answers and yet, everyone will be right.

Very Simple..... If 1000 note is real no one is in lose right? So 1000 is the net lose to the first shopkeeper.....Ankita KatdareA lot of people have confirmed the answer to be Rs. 1200.

Because the cost of item sold is considered separately.

explanation : 200 the rs of item. 800 the rs given back to lady. 800 money taken from near shop.(took 1000 rs but used only 800). ie, net effect shop keeper lost 1800.

She gave Fake note (1000)

Shop keeper 1 : Exchanged Fake note and Get 1000 Rs to his store.

Shop keeper 2 : Reverted the fake note to SK 1 and took his 1000.

Now Shopkeeper 1 has 1000 Fake note & He lost the 800 Rupees & 200 (items). Total 1000 loss to the SK1

The lady had taken 200 worth goods and 800 cash for a note which has no value.

Since the shopkeeper tried to change the note which has no value, the other shop took 1000 original rupees back.

So the total money in terms of cash and goods is 2000

**Rs. 1800**[

**Rs. 1000**[To Lady => Rs.200 (Goods) + Rs.800] +

**Rs. 200**[Change Left => Rs.200 (Rs.1000 - 800)] +

**Rs.800**[To SK2 => Rs. 200(Change Left) + Rs. 800 (From his Pocket)]]

Well i Have seen alot of answers to itAnkita KatdareA friend asked me this question, the other day -

If you are going to reply with an answer, please provide a detailed solution.

So lets get to it line by line

1st case- lady buys goods worth 200

This make her +200 in goods value and sk1 at - 200 goods value and sk2 is out of scene(OoS)

Noe lady pays 1k

This makes lady at +200 goods value and less 1k cash value= net 800 loss value

Sk1- becomes -200 goods value and +1k cash value= at 800 gain

Sk2 is OoS

Noe sk1 gives sk2 1k

Now lady is OoS here standing at 800 loss

Sk1 is at -200 goods value plus 1k from lady less 1k to sk2= -200 good value

Sk2 is now at +1k from sk1

Now sk2 pays sk1 1k for his exchange

Lady is OoS at 800 loss value

Sk1 got 1k from sk2 which makes him stand back to -200 goods loss and 1k cash= 800 gain

Sk2 Is at 0 loss now

Back to sk1 pays back to lady

Now lady has 200 worth goods and 800 cash from sk1 equalling her 1k value

Sk1 becomes settled for now at 200 cash against 200 valued goods at exchange

Sk2 is at no loss

Now trick part

1k note wid sk2 is fake

Lady OoS wid 200 goods nd 800 cash

Sk1 OoS wid -200 goods + 200 cash

Sk2 at - 1k fake note

Sk2 takes 1k from sk1

Lady OoS wid 200 goods nd 800 cash

Sk1 is at +200 cash - 200 goods -1k to sk2 = a loss of value of 1000

Sk2 is settled at 0 loss as + 1k from sk1 - 1k fake note

This concludes the total loss is

Lady OoS at the end having no loss no gain

Sk1 at 1k loss of fake note( 200 goods loss plus 200 cash he has less 1k fake note)

Sk2 at no loss no gain at 0 value

Conclusion

Sk1 had to bear loss of rupees 1000

Shopkeeper is making no profit by selling. What does it imply:

If he sells the item the loss is zero.

If he couldn't sell an item the loss is 200

If he gives it for free, the loss is 400

If he gives an item and makes additional loss of 800, total loss is 1200.

otherwise it will be 800 Rs.

Consider the problem like this.

loss of shopkeeper = profit to lady , So to get the loss of shopkeeper, calculate how much money is there in lady's hand.

Simply at the end with goods its 1000Rs and without goods its 800Rs.

otherwise it will be 800 Rs.

Consider the problem like this.

loss of shopkeeper = profit to lady , So to get the loss of shopkeeper, calculate how much money is there in lady's hand.

Simply at the end with goods its 1000Rs and without goods its 800Rs.

Shopkeeper has to give 1000 to other shopkeeper as its a fake note.

So...Answer is 2000

200( that lady bought some things) + 800(he gives to lady as remaining change) + 1000(the fake note change for the other shopkeeper).

So totally 2000

Lady received a good of Rs. 200 and cash of Rs. 800

Second shopkeeper takes Rs. 1000 back from first shopkeeper against fake note

the other shopkeer is there just to confuse.he has no role to play..the lady has given 1000 rs fake not so the loss is 1000 only..ya but as the goods includes profit margin as well the actuall loss will be less than 1000.

the other shopkeer is there just to confuse.he has no role to play..the lady has given 1000 rs fake not so the loss is 1000 only..ya but as the goods includes profit margin as well the actuall loss will be less than 1000.

**FINAL (and real) ANSWER IS 1000 Rs. !!!!**

EXPLANATION: FOR THE FIRST TIME WHEN SHOPKEEPER (on whom loss is incurred) IS TAKING A FAKE NOTE (VALUE = 0), HE IS GIVING OUT EQUIVALENT REAL MONEY (Rs. 800) PLUS GOODS (Value = Rs. 200). HE INCURRED LOSS OF Rs. 1000.

EXPLANATION

IN SECOND TRANSACTION, HE RETURNED

**THAT SAME AMOUNT**THAT HE

**BORROWED EARLIER**FROM THE OTHER SHOPKEEPER. SO, NO EXCHANGE HAPPENED!!!

**OR THINK IT LIKE THIS:**ASSUME THAT SHOPKEEPER TO SHOPKEEPER TRANSACTION NEVER HAPPENED AND SHOPKEEPER TO WHOM THE FAKE NOTE WAS PRESENTED HAD 800 Rs. CHANGE. NOW WHEN HE IS PRESENTED WITH 1000 Rs. FAKE NOTE HE GIVES TO THE LADY 800 Rs. CASH AND GOODS WORTH 200 Rs. (EQUAL TO 1000 REAL RUPEES). SO TOTAL LOSS = 1000 Rs.

Just do a practical here. Put ten Rs. 100 notes under Sk2 and take a piece of paper and write Rs. 1000 fake note on it. SK1 has no money. Now, lady comes to the shop and buys Rs. 200 worth of products. She gives a note of Rs. 1000 (fake) to the shopkeeper. He has no money in change, so he goes to shopkeeper 2 for change in exchange for Rs. 1000 (fake) note.

He gives Rs. 800 (real money) to the lady and keeps Rs. 200 (real money) with him. He has only Rs. 200 (real money) with him now. Lady is gone with Rs. 200 worth of products and Rs. 800 cash (real money).

Shopkeeper 2 comes and says the Rs. 1000 note is fake.

Here is the underlining part now.

Shopkeeper 1 has to return Rs. 1000 (real money) to shopkeeper 2, but the lady has already gone with Rs. 1000 (Rs. 200 worth of goods and Rs. 800 (real money)). Shopkeeper 1 has only Rs. 200 (real money) with him at this time. So, in order to return Rs. 1000 (real money) to shopkeeper 2, shopkeeper 1 has to arrange Rs. 800 (real money) from somewhere.

Now, some people are saying that shopkeeper 1 sold Rs. 200 worth of products and has Rs. 200 (real money) now. How can he sell something when the lady gave him nothing. She just robbed him.

Therefore, lady took Rs. 800 cash (real money).

Shopkeeper 1 has to return Rs. 1000 (real money) to shopkeeper 2, but shopkeeper 1 has only Rs. 200 (real money) with him. He cannot ask the lady to return Rs. 800 (real money) because she is gone. He has to arrange for Rs. 800 (real money) from somewhere.

Also, shopkeeper 1 was robbed of Rs. 200 worth of products.

800+1000+200 = 2000.

Shyam_puzzleAns = 1000. Two ways to solve it - A and B.

A. Keeping the two transactions separate makes for easy solution -

Hence, you see the only loss happened with the lady, which amounts to 1000.

- With lady, inflow is fake note, outflow is goods worth 200 n 800 cash, so net outflow is 1000, hence loss is 1000.
- With the other keeper, two deals happen -

- first inflow is real 1000, outflow fake note.
- second inflow is fake note, outflow real 1000.
- therefore, net transaction is 0. so no profit, no loss there.

B. If u insist on taking transactions as it happened then here it goes -

As you can see, in the entire transactions, the first keeper NEVER USES HIS OWN MONEY UNTIL he has to give back 1000 to other keeper, that is when HE GIVES 800 OF HIS OWN MONEY n 200 which was left with him.

- inflow from lady, fake note.
- Went to other keeper, inflow is real 1000, outflow fake note.
- Came back to shop, gave lady goods worth 200 n real 800. So outflow in cash value so far is 1000 n inflow is 200 which is still left.
- Other keeper comes back, inflow is fake note, outflow real 1000. To give this 1000, first keeper uses 200 that was left (from above point) n HAS TO ADD 800 OF HIS OWN MONEY. so net outflow is 800.

So, the first keeper's loss is goods worth 200 plus 800 given to other keeper, total of 1000. Remember that the 800 given to the lady was not his own money, it was the other keepers money! (IN THIS TRANSACTION CASE).

Therefore, net loss is 1000.

Hope I could get my points across. Think it over, even play act it if u want to 😀

irockerFINAL (and real) ANSWER IS 1000 Rs. !!!!

EXPLANATION: FOR THE FIRST TIME WHEN SHOPKEEPER (on whom loss is incurred) IS TAKING A FAKE NOTE (VALUE = 0), HE IS GIVING OUT EQUIVALENT REAL MONEY (Rs. 800) PLUS GOODS (Value = Rs. 200). HE INCURRED LOSS OF Rs. 1000.

IN SECOND TRANSACTION, HE RETURNEDTHAT SAME AMOUNTTHAT HEBORROWED EARLIERFROM THE OTHER SHOPKEEPER. SO, NO EXCHANGE HAPPENED!!!

ASSUME THAT SHOPKEEPER TO SHOPKEEPER TRANSACTION NEVER HAPPENED

OR THINK IT LIKE THIS:(because what was initially taken, was returned later)AND SHOPKEEPER TO WHOM THE FAKE NOTE WAS PRESENTED HAD 800 Rs. CHANGE. NOW WHEN HE IS PRESENTED WITH 1000 Rs. FAKE NOTE HE GIVES TO THE LADY 800 Rs. CASH AND GOODS WORTH 200 Rs. (EQUAL TO 1000 REAL RUPEES). SO TOTAL LOSS = 1000 Rs.

Think!!!

Cheers!!!

As the shopkeeper return 800 to the lady.

He paid 1000 to the other shopkeeper and 800 to the lazy.

What about the rs. 200 worth of products she took.Irfan AminAnswer is 1800:

As the shopkeeper return 800 to the lady.

He paid 1000 to the other shopkeeper and 800 to the lazy.

Anyone here has another explanation?

1. Rs 200 is loss of good

2. Rs 800 given to lady

3. Rs 1000 which he has given to the shopkeeper on the behalf of fake note.

total of above amt. consider as a loss face by the shopkeeper.

that is 200+800+1000 =Rs 2000/-

check this out and think again.

the lady got 1000rs of free things

the money that sk2has given goes fully to the lady because she got 800rs which sk1 got from sk2 and the goods and the 200 rs cash

sk1 has to give money INCLUDINGthe 200 rs cash to make up 1000rs

so sk1 hasloss of 1000+1000=2000

Anoop you are considering the sold value item while giving it to the lady and deducting from the Shopkeeper 1. This sold item value is recovered from the shopkeeper 2 while getting the change cash. But when the shopkeeper 1 has to return the whole 1000rs to shopkeeper 2 we have to consider deducting the item value again (that he had gained from the change cash earlier) the shopkeeper 1 is now losing while returning the change cash. So it will be 0-200+1000-800-1000-200Anoop KumarI am considering sold Item value also . The table I given is clearly showing this.

I know explaining this orally is difficult that's why I calculated on totally math based.

Shopkeeper of the next shop is in no profit and no loss situation, because he gave Rs1000(Suppose Rs 100*10) and get back Rs 1000.

Now it's between Lady and the Shopkeeper,

Loss of Shopkeeper=Profit of Lady

Now, Lady's profit is goods worth Rs 200 + Rs 800(Change given by Shopkeeper)

So, Loss of Shopkeeper is Rs 1000.00

HENCE PROVED

I am a Commerce student not an Engineer. PEACE

the people who are saying 1000 is actually missing "the stock has been also reduced in the shop of first shopkeeper".

She gets a change from shopkeeper 2.

Gives 200 REAL money to Shopkeeper 1 and gets 200 worth of goods in return. Right now, the net loss for Shopkeeper 1 is 800. Shopkeeper 2 comes to get his 1000rs back. Now the loss is 1800.

2nd step she took was to give 200 money for 200 goods earning shopkeeper 1 profit of 200.

3rd step was taken by shop keeper 2 when he demanded his 1000 rs back.

Shopkeeper 1 who thought he had a profit of 200 realized that he had not profited at all. He gives 1000 rs to the Shopkeeper 2 but and is only left with the consolation that he at-least had 200 for the goods he gave to the lady.

Here is my way of explanation. Since this puzzle has 3 people i will consider profit and loss for each.

1. First, the next shop's shopkeeper.

He lose 1000 rs real money for fake note and again got his money back. So no loss and no gain.

**Loss=0**

Gain=0

Gain=0

2. Second, the lady.

She invested 1000rs fake money and got real money of 800 rs+200 rs worth goods.

So her loss is nothing but gained 1000rs.

**Loss=0**

Gain=1000rs

Gain=1000rs

3. Third, The shopkeeper.

Now the shopkeeper all he has is fake money of 1000rs.. Since he selling goods with zero profit What he gained is 1000 rs fake money. So it is loss only.

**Loss=1000rs**

gain=0

gain=0

Now it is obvious that shopkeeper losses his money 1000 rs to that lady.

Shop keeper1 (gives item worth Rs.200 + returns Rs 800 to lady)= Rs.1000

Shop Keeper1( gives Rs.1000 to Shop keeper2)= Rs.1000

No. That came from the Rs.1000 he got from SK2. Ultimately the bottom line is that the lady got back a real Rs.1000 value for a fake Rs.1000 note.Kirti DeokarShop keeper1 (gives item worth Rs.200 + returns Rs 800 to lady)= Rs.1000

There's no use of it...

Let me explain this with a simple equation.

Let + denote credit and - denote debit

Owner's net balance = +1000(Received from neighbour in exchage of the note given by customer)-200(Product value)-800(Balance he gave to the customer)-1000(Amount he gave to neighbour after he said that it was a counterfiet note)

**Owner's net balance = -1000**

Since the final result has - sign, it is a loss for Owner.

Let me explain this with a simple equation.

Let + denote credit and - denote debit

Owner's net balance = +1000(Received from neighbour in exchage of the note given by customer)-200(Product value)-800(Balance he gave to the customer)-1000(Amount he gave to neighbour after he said that it was a counterfiet note)

**Owner's net balance = -1000**

Since the final result has - sign, it is a loss for Owner.

Now Asssume I recieve Rs 1000 (Fake) then my deposit initially after swapping the note is Rs 6000. I give out Rs 800 and Goods worth Rs 200/-. So I now have 5000/-. Then the shop keeper 2 comes and demands Rs 1000/- which makes my deposit Rs 4000/- at the end.

Hence I deviating from ideal conditions to conned conditions the total deposit difference is Rs 4000 - Rs 5200= - Rs 1200/-

Thus the loss shopkeeper suffered is of Rs 1200/-

he paid to other shopkeeper 1000/-

total loss = 2000/-

the shopkeeper2 gave him 1000/(in the form of change)- for that he have returned 1000/-to re-place the fake note.so we can say that 200/- + 800/- is now his money.since the note given by the lady was fake we can assume that the shopkeeper1 got nothing.but he gave 800/- as balance and goods worth 200/-.so total loss is 1000.

against 1000 fake Rs. shopkeeper give 800 to lady and 1000 to other shopkeeper and 200 cost of product

but while the shopkeeper 1 gave 1000 /- to shop keeper 2 ,he had given back in the form of change . there is no loss for both because there is only exchange of money right?Rajeev SudanAns is 2000.

against 1000 fake Rs. shopkeeper give 800 to lady and 1000 to other shopkeeper and 200 cost of product

no no he need to give 1000 rupees back to the shopkeeper and he didn't received his actual two hundred from the customer and the answer would be 1200Saandeep SreerambatlaThe loss is 1000.

Since he sold 200rupees of goods and got original 200 from other shop keeper so there is no loss.

Next comes he gave 800 away to the lady who deserves.

But when the note is fake, he has to give back 1000. so I think answer is 1000.

SREENIDHI Tbut while the shopkeeper 1 gave 1000 /- to shop keeper 2 ,he had given back in the form of change . there is no loss for both because there is only exchange of money right?[/QUOTE

I think answer would 2000 as mentioned above by rajeev sundan and he's absolutely rightVIKASH SEELAMno no he need to give 1000 rupees back to the shopkeeper and he didn't received his actual two hundred from the customer and the answer would be 1200

Now i get an instinct that @Rajeev Sudan answer would be apt.

Total loss=200(product cost)+800(change given)+1000(fake note loss)=₹2000

we can consolidate it as let the sk1 had already got the change from sk2 for exact 1000/-

now the lady gave 1000/- fake note to him.sk1 gave the balance 800/- to lady which is real and commodity that costs 200/-.since in the question it's already mentioned that he makes no profit now he have a loss of 1000/- due to the fake note.

Explaining again - my viewSREENIDHI Teven then i think the answer is 1000/-.

we can consolidate it as let the sk1 had already got the change from sk2 for exact 1000/-

now the lady gave 1000/- fake note to him.sk1 gave the balance 800/- to lady which is real and commodity that costs 200/-.since in the question it's already mentioned that he makes no profit now he have a loss of 1000/- due to the fake note.

Total loss incurred - lets assume as you sais that shopkeeper has exact change for ₹1000.

Now the lady bought a product for ₹200 and gave ₹1000(fake) to shopkeeper.He gave ₹800(balance) from his cash counter.now he realises later that the ₹1000 note was fake so cinsolidating the loss-₹200(product)+₹800(SK1 cash)+₹1000(fake which he cannot use in future)=₹2000.

2000Ankita KatdareA friend asked me this question, the other day -

A lady buys goods worth Rs. 200 from a shop. (shopkeeper is selling the goods with zero profit).

The lady gives him Rs. 1000 note. The shopkeeper gets the change from the next shop and keeps Rs. 200 for himself and returns Rs. 800 to the lady.

Later the shopkeeper of the next shop comes with the Rs. 1000 note saying "duplicate" and takes his money back.

How much LOSS did the shopkeeper face?

The answers that people came up with were - Rs. 1000, Rs. 2000, Rs. 1800, Rs. 1200 and Rs. 800

so he totally loss 2000rs

Ankita KatdareRs. 1200

i:e, 200rs worth item+ 800rs cash back to the lady + 1000rs cash to the shopkeeper.

I'm asking one simple question Who gave 800rs to the lady and 1000 rs for the second shopkeeper

The answer is 2000. Goods worth 200+800 that already given to the lady+1000 for the duplicate note

Thank you.

so what is the final answer ?

Loss for the shopkeeper is :

200(goods worth)+ 800(change he returned to lady) = 1000/-

Also point to be noted, the other shopkeeper has come saying it’s a duplicate note and takes away the original 1000/- note so now the shopkeeper has to return the 1000/- to the other shopkeeper which in turn makes a loss of 1000/-

so the total loss the shopkeeper had was 2000/-

Since there is no profit or loss, loss of product would be= Rs. 200 (Cost of Purchase)

Need to pay the person who returned duplicate Note to

the shopkeeper = Rs. 1,000

The shopkeeper return Rs. 800 to the buyer who gave

Rs.1,000 note which was duplicate = Rs. 800

-------------

Total Loss************************************************= Rs. 2,000

The right answer is 800rs...

The shopkeeper didn't loss anything to the lady.

Think it carefully...the shopkeeper return 800rs real money plus goods of 200rs to the lady...and keep 200rs real money with him...

When the neighbor come back for his own money which is 1000rs..the shopkeeper took 1000rs from his pocket and give it to the neighbor..at this point,the shopkeeper loss 1000rs... because he gives his money...

Even though the shopkeeper gives his 1000 from his pocket..he still have 200rs with him..when we minus that (1000-200)he losses only 800rs..

He didn't loss 1000rs because that 200rs is a real money from the neighbor itself..also that 200rs is the price of the goods from the lady ...

So, the shopkeeper loss 800rs in total.

(1000-200=800)

- The right answer is 800rs...

The shopkeeper didn't loss anything to the lady.

Think it carefully...the shopkeeper return 800rs real money plus goods of 200rs to the lady...and keep 200rs real money with him...

When the neighbor come back for his own money which is 1000rs..the shopkeeper took 1000rs from his pocket and give it to the neighbor..at this point,the shopkeeper loss 1000rs... because he gives his money...

Even though the shopkeeper gives his 1000 from his pocket..he still have 200rs with him..when we minus that (1000-200)he losses only 800rs..

He didn't loss 1000rs because that 200rs is a real money from the neighbor itself..also that 200rs is the price of the goods from the lady ...

So, the shopkeeper loss 800rs in total.

(1000-200=800)

Not quite. Rs.200 is real money for which he gave goods of equal value, which cancels out. He paid out Rs.1000 to the other to take back the fake note.

All that happened is that one fake note changed hands. The loss is the value of that note.

1000 Rs is wrong answer why because after selling 200 Rs to the customer he will get some profit on that 200. So the answer in between 800 to 1000
