Question

8 balls ->7 same weight but 1 is heavy. 2 tries to weight on weight scale. Find heavier bal

Answer 1

Answer:

First weight 5 balls and second weight 2 balls.

Step-by-step explanation:

    1. Select any 5 balls, keep 3 in one side of weight scale, say it side 'x' and 2 on other side of weight scale, say it side 'y'.

   2(a). If it do not balance and y is heavier, keep one from the 'y' on one side and second on other side simple.

 2(b). If it do not balance and x is heavier, select any two from the three and put one on one side and second on other side.

if two balances then 3rd which was kept aside is heavy if it don't balances judging the heavy ball is easy.

   3. If it balances then the heavy ball is any of the 3 balls which were left aside. select any two from the three and put one on one side and second on other side.

if two balances then 3rd which was kept aside is heavy if it don't balances judging the heavy ball is easy.
