Okatelugodu:

If there are 13 wooden blocks of same dimenions, but 1 of them is lighter or heavier than the remaining 12. Given a common balance, how can you find the block with a different weight in just 3 weighings







looks very simple... If some one do not find out.. here is solution..

1st lot:
take 3,3 -- and weigh, if equal, put aside. if not equal, weigh 1 and 1, if it is equal, 3rd one is lighter.., or one of the may be equal.. done deal. if 6 are equal ones,2nd step:

take another set of 6 (3, 3), if they are equal, left one is lighter..

The catch here if you donot know if the odd block is heavier or lighter. All you know is that it is of different weight..

6 on one side and 6 on other side- if both are equal then 13th one is lighter weight

Let's say one side is lighter- then we have eliminated 7 blocks

then 3 on one side and 3 on other- heavier side 3 are eliminated

Now we have 3- one on one side and one on another side- if both are equal then 3rd one is lighter else lighter side block is lighter!

We only need 3 weighings! :-)

now measure 3(1) vs 3(2) if not equal then one of them has odd man. now measure 3(3) and determine single one weight and which one has odd one from 3(1) and 3(2).

pick the odd one and take two from them and measure...if equal then the third one is odd one...if not then you already know the odd one (compare with single one weight)




this is not a separate measure but the follow up of the first measure

divide them into 3(1), 3(2), 3(3), 3(4) and 1(x) groups (four groups of each containing 3 and 1 group with one).

now measure 3(1) vs 3(2) if not equal then one of them has odd man. if equal then (note down single one weight 3(1)/3) proceed to 3(3) vs 3(4)...if euqal then 1(x) is odd man...if not then. determine which one is not equal to 3(1)/3 times 3 in 3(3) and 3(4)...and that one has odd man (so far we had two measures). now take the odd one from 3(3) and 3(4)...let us say 3(3)...then take two from 3...and measure it...if equal then the other one is odd...if not equal then you already know the odd one (compare with 3(1)/3).
