First put 6 balls on each side and weight them. : f" z4 o, P. S" z6 q* v$ N
Take the heavier 6 balls, split them into 2 groups of 3, and weight them again.1 p: ~* y6 t' q; z( q4 E
Take 2 out of the 3 heavier balls and weight them. If one of them is heavier than the other, then that one is the target that we were looking for. If both of the balls have the same weight, then the remaining unweighted ball is the target.
