    I had solve this puzzle when I was in college
    people normally don't get answer for this puzzle because they tend to forget "( )" and "^" (power to) are part of the mathematical expressions ๐Ÿ˜€

    Answer is (8 - 7 * 6) * (5 - 4 ^ 3) = 2006

    Here is a new one for all CEians

    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 ๐Ÿ˜

    OK ! I know the answer to this from my engineering days ...
    Many others may also know it. Anyway let me wait for people to try.

    Clue : There is nothing extra ordinary in this puzzle. Just required some common sense.

    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.
    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.
    โ€‹Handler's Names: Jane, Mark, Ruth and Terry
    Dog's Names: Tiff, Patti, Jago and Kelly
    Breed: Alsatian, Collie, Labrador and Doberman
    Level: Starters, Elementary, Novice or Senior

    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..

    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 ?

    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|......

    correct me if i m 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_KOh really? ๐Ÿ˜‰

    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/

  • silverscorpion

    @silverscorpion-iJKtdQ Jan 20, 2011

    shreyasm89What'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. ๐Ÿ˜€

    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. ๐Ÿ˜€๐Ÿ˜€
