divide the 8 balls into 2 sets such that each set contains 4
balls. Weigh both the sets. Now the set which weighs less is
again divides into 2 sets such that each set will contain 2
balls.Now weigh these 2 sets and again the set which weighs
less will be divided into 2 sets with one 1 ball each.Now if
you weigh you can find out the ball which weighs less than
the rest.
