Puzzle Busters Corner

here is the answer:
[8 - (7*6)] * [5 - (4^3)] =2006
step1: 7*6 = 42
step2: 8-42=-34
step3: 4^3 = 4*4*4= 64
step4: 5-64=-59
step5: -34 * -59
step6: 2006 😀​

Well I am posting first time on this forum , must say it's a great place to share stuffs. Well Big K all are asking literally begging you to tell the answer to the question puzzle you've posed on us, so speak out dude!!!! I'm also eager to know the answer. I thought the correct numerical to be 1 and 2 as all other numbers are going in declining order but cannot relate them with 2006 expression!! Please explain.
Anyway here's a brainteaser link which has got some of the great mind teasers -

No Deepac... The answer is here:

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.

i have 2 puzzles:

1) how many cars r thr in US/INDIA?
2) y r manholes alws round?

these 2 r askd often give a logical answer.....plz
thks

Here's one:
What's something you never want to get, but if you do get it you never want to lose it?

nick9162) y r manholes alws round?

Round covers won't fall in at any case, where as square covers can fall in when placed diagonally! 😀

@Ce Designer: Lawsuit?

Hehe, you got it Reya 👍
Here is another:
A horse is galloping at high speed on a road. Along the same road comes a bull galloping in the opposite direction.
They both crash into each other.
Who is to blame? The horse, or the bull?
P.S. the answer is a funny one.

No takers here? 😯

The bull is to blame.
Because he has no brakes while the horse has brakes (bit).

Woah... Nice one... I thought that but, didn't strike!!! 😛

Now solve this one... Very easy one... A classic one too! 😀

You are in a candle lit room with a single wooden door, no windows and three light switches labeled A, B and C. You cannot by any means see anything outside the room. The three switches are connected to three lights in another room. They are all currently in the off position. You are given ten minutes in the room with the switches then you will be taken to the room with the lights. At that time you need to label each light with the letter of the corresponding switch. How do you do it?

Bro .... I know this... but, I am giving chance to others.....
Let them try .... I will answer if no one knows.

When 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.

There are 2 glowing bulbs. One is hot-this is the first one that you switched on. Label it as A. The other colder glowing bulb can be named as B. The remaining bulb that is not glowing is labeled as C. 😀

Haha, you are right the bull is to blame but the answer i was looking for was:
The bull is to blame because he has horns, he should have blown his horns 😁😉

The following equation is wrong:

101 - 102 = 1

Move one numeral to make it correct

(Caution: Trick) 😁

Dancer_EngineerThe following equation is wrong:

101 - 10[sup]2[/sup] = 1
Right aa?

Oh Yesh...Right! 😁

Using five zero's(0's) with any mathematical equation/operation can anyone bring 120 as an answer ???

K!r@nS!nguUsing five zero's(0's) with any mathematical equation/operation can anyone bring 120 as an answer ???

You mean:

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

Dancer_EngineerYou mean:

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

Yes....

K!r@nS!nguYes....

I got answer as 2.

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

How did you get 120? 😕

Let others give a trail....

(0!+0!+0!+0!+0!)!=(1+1+1+1+1)!=5!=120.

Reya(0!+0!+0!+0!+0!)!=(1+1+1+1+1)!=5!=120.

you are damn right !!! keep going reya...

Ohh Damn! 😔

Reya(0!+0!+0!+0!+0!)!=(1+1+1+1+1)!=5!=120.

Cool! 😎

Reya(0!+0!+0!+0!+0!)!=(1+1+1+1+1)!=5!=120.

(She is Reya after all) FACTORIAL 😁

Ah!!! Where is the next question now... 😛

Praveen-KumarAh!!! Where is the next question now... 😛

Here you go:

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?

Oyee! Actually, the question with the answer is tricky!!!
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???

I didn't understand your solution dude 😕

C (5) >> W ?

Cashier gives five to waiter...

Is the answer right???

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

But both A and B pay 15 each.

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

But both A and B pay 15 each.

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

They 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! 😀

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! 😀

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! 😀

Ok.

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?

Eiii!!! 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...
Cashier returns back 5$, which you didn't mention...
So, technically, it is not 14 + 14 + 3, but it is 14 + 14 - 5 + 3!!!

Dude, 14 + 14 - 5 + 3 = 26.
But the bill is $25. 😛

I think you are pretty close to the solution. 😁

The 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.

This is what even I said!!! 😲

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

Nope, I think the statement meant total of 14 and 14 is 28.
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. 😀

Dancer_EngineerBoth of you are right.
Praveen, I didn't have the solution with me earlier. 😀

Yay!!! 😀 Mine is right!!! 😁

Praveen-KumarYay!!! 😀 Mine is right!!! 😁

Yes you are. 😛 😁

The_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-

the positive square root is the culprit
we have to consider
(3-5/2)(3-5/2)=-(2-5/2)(2-5/2)
