    easy.

    first balls: a b
    second balls: c d
    third balls: e f

    now we weight, b and c.. d and e only..
    if b = c, d = e then we can conclude b c f / a d e
    if b =/c , d =/e then we can conclude b d f / a c e ( if b and d heavier )
    if b = c, d =/e then b c e / a d f.


    you dont have to know which one heavier or lighter, you can simply group them up with simple measurement
    question?

  3. kyky added a post in a topic Hats on a death row!! One of my favorites puzzles!   

    its lack of information.. you should list how many red hat, how many black hat..

    if we dont have that number, it could be all red or all black.

    my answer is 5 times.. heres how it goes

    27 coins = 8 8 8 1 1 1. thats a b c d e f
    if a = b, a = c, we go to the ones.. if d = e, then the answer is F. COUNT = 3
    if a = b, a = c, we go to the ones.. if d =/ e, we weight f. if d =/ f then the answer is D. COUNT = 4
    if a = b, a = c, d =/ e, d = f, the answer is E. COUNT = 4

    now we go to the if the diff coin is at a or b or c.
    if a = b, a =/ c, then we measure c.

    before we go further, i want to show you how we solve 8 coins with 3 scaling.
    8 coins we devide it into twos.

    8 coins = 2 2 2 2, thats w x y z.
    if w = x, w = y, then we weight 1 coin from w, and 1 coin from z. if w = z, then the other coin from z is the answer.
    if w = x, w =/ y, then we weight 1 coin from w, and 1 coin from y. if w =/ y, the answer is that coin from y.
    if w =/ x, w = y, then we weight 1 coin from w, and 1 coin from x. if w = x, the other coin from x is the asnwer.
    if w =/ x, w =/ y, one coin from W is the answer. we weight 1 coin from W, 1 coin from x or y or z..
    TOTAL COUNT = 3


    if a = b, then the coin is at C. total count 4.
    if a =/ b, a =/ c, then the coin is at A. total count 5.
    if a =/ b, a = c, then the coin is at B. total count 5.
