    It seems this one has no takers. Well, it wasn't a puzzle 😉 . Here's the most logical answer 😁

    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.

    Puzzle alwaz seems easy when u have the solution with u😉

    Looking for some more!!!!
    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 ?

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

    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.

    [​IMG] I think I got it right.

    well a second possibility cud be as follows:
    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...

    It Looks so plain you would think nothing was wrong with it. In fact,
    Nothing Is wrong with it! It is unusual though. Study it, and think about it, but You still may not find anything odd. But if you work at it a bit, you might find out."

    I am posting the answer!

    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.

    The four people in this puzzle all competed in different classes of dog agility at a recent competition. The competitions all required the dogs to run over jumps, through tunnels and various other obstacles in as quicker time as possible. Each had a different result - one came first, one third, one fourth and one ninth. All four dogs were each of a different breed.

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

    1. If Tiff finished first then Terry finished fourth.
    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.

    Imagine a prisoner in a prison. He is sentenced to death and has been told that he will be killed on one day of the following week. He has been assured that the day will be a surprise to him, so he will not be anticipating the hangman on a particular day, thus keeping his stress levels in check.

    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!

    Ponder this?

    If we come back thinking this we think that this is true but its not true.
    this is a paradox.
    on sunday he have a chance to die in next 6 days , on monday next 5 days and tuesday next 4 days so there is a possibility to hang him..

    how can he determine the heavier one ?
    Split the balls into two groups of three and one group of two.

    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.

    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|......

    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.....

    We all knew that the absolute value would be the same. But I'm not sure how that solve's the biggie's ques
    integratdbrains
    The_Big_K
    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

    Taking mod on both sides. while subtracting the denominators of the numbers should be same! one cannot cancel the numbers!
    /(3*2-5)/2/= /(2*2-5)/2/
    /1/=/1/

    The common CE sentence!"correct me if m wrong!"😒😁

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

    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. 😀😀

    6561/3=2187

    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.

    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?

    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. 😀

    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)

    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!!!

    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.

    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.

    Try 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)

    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...!

    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.

    Three clocks in the train station give the following readings:
    CLOCK A: 8:00, CLOCK B: 8:50 and CLOCK C: 8:20

    Any one of the above clocks is 20 minutes fast, one clock is slow and one clock is off by half an hour.

    Help the passengers figure out what time it really is.

    I got a solution by guessing answer and coming back. Answer is 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.

    Steps..... x/n-1 = x/n * 8/6 -- (1) [Where x is the length,n is no of poles and 8/6 is data(1+2/3)].
    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.

    The following equation is wrong:

    101 - 102 = 1

    Move one numeral to make it correct

    (Caution: Trick) 😁
    Can it be
    101 = 102 - 1
    Just shift top minus line.

    4, 6, 9, 12, 15, 18, 21, 26, 30, _ , _ , _ ....
    Logic is...
    4,12,21.... +8,+9, diff is 1, So next 21+10 ie 31
    6,15,26.... +9,+11, diff is 2, So next 26+13 ie 39
    9,18,30.... +9,+12, diff is 3, So next 30+15 ie 45
