We have "5 = 4".

Subtract 3 from both sides: 2 = 1.

Russell and the Pope are are two people.

Since "2 = 1", they are one.

**Try this one now -**

Oh really? 😉nehaPuzzle alwaz seems easy when u have the solution with u😉

Looking for some more!!!!

Try this - ( should be easy )

-6 = -6

9-15 = 4-10

adding 25/4 to both sides:

9-15+(25/4) = 4-10+(25/4 )

Changing the order

9+(25/4)-15 = 4+(25/4)-10

(this is just like : a square + b square - two a b = (a-b)square.)

Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.

So it can be expressed as follows:

(3-5/2)(3-5/2) = (2-5/2)(2-5/2)

Taking positive square root on both sides:

3 - 5/2 = 2 - 5/2

3 = 2 😒 😁

What's wrong with the above ?

Taking positive square root on both sides:

3 - 5/2 = 2 - 5/2

Taking mod on both sides. while subtracting the denominators of the numbers should be same! one cannot cancel the numbers!

Or something's wrong in there 😁

Find out!

**-The Big K-**

**here is my explanation**

This is a typical case of optical illusion. It is very simple. Take the 'tan' of the angle at the top using the upper block. I mean, in first figure - take the tan of top angle using the top green triangle & in the second, the top red triangle.

The value is different in each case. This explains that the second triangle is not a perfect triangle.

I think I got it right.

Crooook

**let me try explaining**

well a second possibility cud be as follows:crookThis is a typical case of optical illusion. It is very simple. Take the 'tan' of the angle at the top using the upper block. I mean, in first figure - take the tan of top angle using the top green triangle & in the second, the top red triangle.

The value is different in each case. This explains that the second triangle is not a perfect triangle.

I think I got it right.

Crooook

if we look at the picture... we shall notice the base of the triangle is longer w.r.t the perpendicular. this is because (in the first picture) the triangle in red has a long base to add up with the base of the initial triangle....

now if we re-arrange the blocks... we have placed this longer base red triangle on the top while a triangle with a smaller base (the green one) is placed at the bottom... now to maintain the same base as b4 the two " L" blocks have to be placed at a block's gap.... more over they bein initially designed to interlink to form a vertical block have now been used vertically... so they go out of order...

i hope i was fair enough to explain my point... do let me know in case of ne doubts...

**Question:**In the basement there are 3 light switches in the off position. Each switch controls 1 of 3 light bulbs on the floor above. You may move any of the switches, but you may only go up stairs one time. How can you determine which switch controls each light?

I guess it should be easy 😁

Turn on any switch and keep it 'ON' for some time. Switch it off. Now turn on another switch and rush to the floor above.

1. The bulb which is glowing corresponds to the switch which is presently 'ON'.

2. Touch the other two bulbs: The one which is warm(/hot) corresponds to the switch which was turned on initially.

3. The remaining bulb corresponds to the third (remaining) switch.

Can you work out who handled which dog, at what level each competed, the place each finished in and the breed of each dog?

2. If Terry finished fourth then Jago is a collie otherwise Jago is not a collie.

3. If Jane competed in the Senior class then she finished third.

4. If Jane competed in Novice then she finished fourth.

5. The dog that finished ninth was an alsatian. This was either Jago, in which case Jago competed in the Elementary class, or this was Kelly, in which case Terry handled Kelly.

6. Mark won Starters.

7. If Mark's dog is called Patti then Patti is a labrador otherwise Patti is a collie.

8. Ruth's dog is called Jago.

9. If Jago finished fourth then she competed in the Novice class otherwise she competed in the Senior class.

10. If Patti finished first then Terry's dog is an alsatian otherwise Terry's dog is a collie.

11. If Jane's dog is a doberman then Jane finished fourth otherwise Jane finished third.

Dog's Names: Tiff, Patti, Jago and Kelly

Breed: Alsatian, Collie, Labrador and Doberman

Level: Starters, Elementary, Novice or Senior

The prisoner starts to think to himself, if I am still alive on Thursday, then clearly I shall be hanged on Friday, this would mean that I then know the day of my death, therefore I cannot be hanged on Friday. Now then, if I am still alive on Wednesday, then clearly I shall be hanged on Thursday, since I have already ruled out Friday. The prisoner works back with this logic, finally concluding that he cannot after all be hanged, without already knowing which day it was.

Casually, resting on his laurels, sitting in his prison cell on Tuesday, the warden arrives to take him to be hanged, the prisoner was obviously surprised!

a person has eight identical looking balls,but one of them is heavier than others, he has a two -arm balancing machine and he can weigh only twice,

how can he determine the heavier one ?

so that i can solve it😁

ankur verma

Split the balls into two groups of three and one group of two.ankur vermaa person has eight identical looking balls,but one of them is heavier than others, he has a two -arm balancing machine and he can weigh only twice,

how can he determine the heavier one ?

Compare the two groups of three.

If one side is heavier, then take two balls from that group and compare them--if neither is heavier, then it's the third ball.

If the groups of three in the first weighing came up equal, then you know that the heavier ball is in the group of two, so you compare the weights of those two.

woot.

Here is a more interesting ques.....

there are 10 identical machines manufacturing medicines,one of them is defective and produces a tablet that is different in weight(not lighter necessary)....using a digital weight once,how will u tell the defective machine from the others?????😕

you can have standard weight of tablet suppose say 10gm....now take one tablet from 1st machine..two tablet form 2nd machine ...3 tablet from 3rd machine and so on..so u must have 55 tablet and u must have total weight equal to 55*(standard weight of tablet)=550..... but actually u dont have because one machine is defective...so measure the weight of 55 tablet together...u can easily find out the defective machine from the difference |actual weight-550|......karan_shah89The result can be generalized for any number of items to be weighed.....for and number that is between any fixed powers of 3!!!!

**Re: and here comes the tough one ( is it ? )**

actually the figure is wrong because...imagine this figure in a geometrical plane.......bottom left corner (0,0)...and top right corner (13,5)...then line joining these points does not pass through any of the points with both integer coordinates...where as in figure it is shown that....line passes through (8,3) and (5,2)....which is totaly wrong.....The_Big_KOkay !

Try this - ( should be easy )

-6 = -6

9-15 = 4-10

adding 25/4 to both sides:

9-15+(25/4) = 4-10+(25/4 )

Changing the order

9+(25/4)-15 = 4+(25/4)-10

(this is just like : a square + b square - two a b = (a-b)square.)

Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.

So it can be expressed as follows:

(3-5/2)(3-5/2) = (2-5/2)(2-5/2)

Taking positive square root on both sides:

3 - 5/2 = 2 - 5/2

Taking mod on both sides. while subtracting the denominators of the numbers should be same! one cannot cancel the numbers!

silverscorpion

well, this is easy.shreyasm89What's the answer?

You take 1 tablet from machine 1, 2 from machine 2 and so on and 10 from machine 10.

Weigh the total tablets in the digital weight.

The total weight should ideally be a multiple of 55. (55 times the weight of one tablet)

See how much is the difference between the total weight and the nearest multiple of 55.

That is the defective machine, and if the total weight is greater than the multiple of 55, then the defective machine produces heavier tablets, and vice versa. 😀

Let's say machine 5 is defective and it produces lighter tablets. Then, the total weight will be 5 less than 55 times the weight of 1 tablet. 😀😀

Here the constant is the distance.

Let consider the time is 'T', velocity is 'V' and distance is 'D' for normal journey.

Equating distances in each case.

Let time in minutes, length in miles initially.

Case1: 120 minutes late

VT = V * 60min + (3/5)*V* ( T + 120min - 60min)

=> VT = 60V + (3/5)VT + (3/5)60V

=> T = 240min = 4hours. Therefore normal journey is 4Hrs.----(1)

Case2: 40 minutes gained from 120 min late.

VT = 50miles + (3/5)*V*(T + 120min - 40min - (50mile/V))

=>using eq.1

=>240V = 50 + (3/5)320V - (3/5)*50

=>V = (5/12)miles/minute. Convert this to miles/hour.

=>v = (5/12)*60 = 25 Miles/Hour.

=>Required Distance is D= VT = 25*4= 100Miles.

Praveen Kumar Purushothaman

Perfect, but you forgot to turn the first switchoff!!! 😛IssueWhen you are in the room, turn ON any of the switch. Leave it as it is for next 10 minutes. At the end of 10 minutes turn ON any of the switches. Now go to the next room.

Haha, you are right the bull is to blame but the answer i was looking for was:IssueThe bull is to blame.

Because he has no brakes while the horse has brakes (bit).

The bull is to blame because he has horns, he should have blown his horns 😁😉

Any Mathematical operation (0 0 0 0 0) = 120 ?

K!r@nS!ngu

Yes....Dancer_EngineerYou mean:

Any Mathematical operation (0 0 0 0 0) = 120 ?

Dancer_Engineer

I got answer as 2.K!r@nS!nguYes....

(0^0) + (0^0) + 0 = 1+1+0 = 2

How did you get 120? 😕

you are damn right !!! keep going reya...Reya(0!+0!+0!+0!+0!)!=(1+1+1+1+1)!=5!=120.

Here you go:Praveen-KumarAh!!! Where is the next question now... 😛

Two friends have a nice meal together, and the bill is $25

The friends pay $15 each, which the Waiter gives to the Cashier

The Cashier hands back $5 to the Waiter

The Waiter keeps $3 as a tip and hands back $1 each

So, the friends paid $14 each for the meal, for a total of $28. The Waiter has $3, and that makes $31. Where did the other dollar come from?

Praveen Kumar Purushothaman

Oyee! Actually, the question with the answer is tricky!!!Dancer_EngineerHere you go:

So, the friends paid $14 each for the meal, for a total of $28. The Waiter has $3, and that makes $31. Where did the other dollar come from?

Let the friends be A, and B.

Cashier be C.

Waiter be W.

A+B (15+15) » C

C (5) » W

W (1+1) » A+B

Total Pay: 14 (A) + 14 (B) - 3 (W) = 25 (C)

Is the answer right???

Dancer_Engineer

I didn't understand your solution dude 😕Praveen-KumarOyee! Actually, the question with the answer is tricky!!!

A+B (15+15) » C

C (5) » W

W (1+1) » A+B

Is the answer right???

C (5) >> W ?

Praveen Kumar Purushothaman

Dancer_Engineer

You say,Praveen-KumarOyee! Actually, the question with the answer is tricky!!!

Let the friends be A, and B.

A+B (15+15) » C

C (5) » W

W (1+1) » A+B

Is the answer right???

Total Pay: 14 (A) + 14 (B) - 3 (W) = 25 (C)

But both A and B pay 15 each.

Praveen Kumar Purushothaman

They get back 1 rupee each from the Waiter na? So, mathematically, check! 😀Dancer_EngineerYou say,

Total Pay: 14 (A) + 14 (B) - 3 (W) = 25 (C)

But both A and B pay 15 each.

Praveen Kumar Purushothaman

Praveen Kumar Purushothaman

A = 15 B = 15 C = -5 W = 3 ------ T = 28 W = -3 ------ F = 25 ------Where, A & B are friends, C is the Cashier, W is the Waiter and F is the Food! 😀

Dancer_Engineer

Ok.Praveen-KumarThey pay 15 each... And in turn, cashier gives back 5, out of which 3 is taken by the waiter. So, the waiter pays back 1 each... This way, they effectively pay 14 each! 😀

So Both A and B pay $14 and the waiter keeps $3,

that makes: $14 + $14 + $3 = $31.

But initially there was just $30,

$15 each from A and B.

Where did this 1 Dollar come from?

Praveen Kumar Purushothaman

Eiii!!! I said, Waiter's bill is to be negated!!! You didn't add the $5 which you got from the Cashier!!!Dancer_EngineerOk.

So Both A and B pay $14 and the waiter keeps $3,

that makes: $14 + $14 + $3 = $31.

But initially there was just $30,

$15 each from A and B.

Okay, then coming to your way itself...

First these two pay 15$ each...

Cashier

**returns back**5$, which you didn't mention...

So, technically, it is not 14 + 14 + 3, but it is 14 + 14 - 5 + 3!!!

Dancer_Engineer

Dude, 14 + 14 - 5 + 3 = 26.Praveen-KumarEiii!!! I said, Waiter's bill is to be negated!!! You didn't add the $5 which you got from the Cashier!!!

Okay, then coming to your way itself...

First these two pay 15$ each...

Cashierreturns back5$, which you didn't mention...

So, technically, it is not 14 + 14 + 3, but it is 14 + 14 - 5 + 3!!!

But the bill is $25. 😛

I think you are pretty close to the solution. 😁

The waitor returned $2 back($1 for each)

The tips of the waitor is $3.

Each gave $15 to the waitor.So the total amount is $30.

$25+$3+$2=30.

"So, the friends paid $14 each for the meal, for a total of $28" is the misleading statement.

Praveen Kumar Purushothaman

This is what even I said!!! 😲ReyaThe bill is $25. If i divide that,each should contribute $12.5

The waitor returned $2 back($1 for each)

The tips of the waitor is $3.

Each gave $15 to the waitor.So the total amount is $30.

$25+$3+$2=30.

"So, the friends paid $14 each for the meal, for a total of $28" is the misleading statement.

Dancer_Engineer

Nope, I think the statement meant total of 14 and 14 is 28.Reya"So, the friends paid $14 each for the meal, for a total of $28" is the misleading statement.

I'm getting confused 😕

I'll post the solution here

**The Solution . . .**

$25 is sitting with the Cashier, $2 with the friends, and $3 with the Waiter. That adds to the required $30.

The mistake is expecting that what the men paid and what the Waiter kept to add up to what the men initially gave. In fact, it is the amount that the meal effectively cost them, plus the amount they received back, that should add to $30.

Both of you are right.

Praveen, I didn't have the solution with me earlier. 😀

Praveen Kumar Purushothaman

Yay!!! 😀 Mine is right!!! 😁Dancer_EngineerBoth of you are right.

Praveen, I didn't have the solution with me earlier. 😀

Sughosh Deshmukh

the positive square root is the culpritThe_Big_KTry this one now -

Oh really? 😉

Try this - ( should be easy )

-6 = -6

9-15 = 4-10

adding 25/4 to both sides:

9-15+(25/4) = 4-10+(25/4 )

Changing the order

9+(25/4)-15 = 4+(25/4)-10

(this is just like : a square + b square - two a b = (a-b)square.)

Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.

So it can be expressed as follows:

(3-5/2)(3-5/2) = (2-5/2)(2-5/2)

Taking positive square root on both sides:

3 - 5/2 = 2 - 5/2

3 = 2 😒 😁

What's wrong with the above ?

-The Big K-

we have to consider

(3-5/2)(3-5/2)=-(2-5/2)(2-5/2)

**The_Big_K whats the answer to this. This is messing with my mind 😕**

yup its 24...rickNew Puzzle!

err! wait ! 😁

I did try Google, Yahoo, MSN & my brain 😁

I'm posting a new question. The one who solves this first gets ...

a smile from me 😁

here we go -

A number of children are standing in a circle. They are evenly spaced and the 5th child is directly opposite the 17th child. How many children are there altogether?

RICK

we have 8,7,6.5,4,3 right..! so 6!*3=2160

we are left with 8,7,5,4...! so i am using 8,5,4...! so (5!/4)-8=(120/4)-8=22

so we have oly 7 left..! so 22*7=154

and we have 2160 and 154 here so 2160-154=2006...! phew it took my whole brain out...!

so the complete result is..!! (6!*3)-(((5!/4)-8)*7)=2006 i hope im right..!

P.s : I used the help of my calculator and of course my brain..! 😀 Thank u again The_Big_K fr such a wonderful puzzle..!

here's a simple puzzle to start your brain engines.

A, B, and C, were all over at D's house when a package was delivered. Each child guessed what was in the box, but only one of them was right. Using their guesses as clues, can you figure out what was in the box?

A said, "It's a laptop computer."

B said, "I'll bet it's a pizza."

C said, "I think a picture or a laptop computer is in the box."

and "It's a picture, for sure," said D.

3 polesrchwhat according to u cud be answer to this puzzle>>?

An electric wire runs for 1 km b/w some no: of poles. If one pole is removed the distance b/w each pole increases by 1 2/6 (mixed fraction). How many poles were there initially?

Hussanal Faroke

**4 poles**in beginning and 3 poles after removing 1. for 1 km wire. if we have 4 poles, each side will be 1000/4 = 250 meters. if we remove 1 pole, each side will be 1000/3 = 333.333 meters, that is exactly 1+2/6 of 250.

Hussanal Faroke

eq(1)* 1/x => 1/n-1 = 1/n * 8/6

=> 6n = 8n-8

=>2n = 8

=> n=4. That means total no of poles

**4.**
