Challenge Answer 44


Find the ball heavier

Compare any 9 balls with 9 others and leave the remaining nine in the box.

If the balance is balanced, the heaviest ball will be among the nine balls in the box and if not, it will be among the nine on the heaviest plate. We divided into 3 groups of 3 this set and repeat the operation. Thus, with two weights we have isolated the heaviest ball from a group of 3 balls.

If we repeat the operation a third time, we have isolated the heaviest ball from the others.
