Divide 8 balls into:
Set A: (3)
Set B: (3)
Set C: (2)

Comparison 1: A and B
if(A=B):
Compare Set C, Keeping one ball in each Pan and find the wrong one!
else:
Either A or B has to has Odd one!
Compare two balls: B1 and B2 and
if(B1=B2): B3 is thewrong one
else: B2/ B1 will be the wrong one :)

Name the balls as 1,2,3,4,5,6,7,8
Pick first 6 (or any 6) balls and put on either side of balance
Case 1:
If it matches then take remaining to balls say 7 and 8 and put on either side.
Now which ever is heavier is the one
Case 2:
If first 6 does not match, then take the 3 balls from heavier side and pick any 2 of them and weigh it.
Case A:
If not same then the heavier is one.
Case B:
If same then the remaining 3rd ball is the heavier one

{{{ Step 1) Pick any 6 ball and weight 3 balls on each rim of justice scale. Step 2) if (weigh's are exactly same in Step1) ) then heavier ball is in remaining 2 balls, put the remaining ball on each rim of justice scale and get the heavier ball. else Get the 3 balls which are on the heavier side of the scale. Pick any 2 balls from 3 and put a ball on each rim of justice scale. If the weighs are same then 3 ball is heavy otherwise heavier ball should be shown in the justice scale - Anonymous April 24, 2013 | Flag Reply
