You have three metal balls: A, B, and C. One is heavier than the other two, which are identical in weight. You place A on the left side of a balance scale and B on the right. The left side sinks. Which ball is the heaviest?
Ball A
Since ball A dropped, it is heavier than ball B. Because only one ball is heavier than the rest, ball A must be the unique heavy ball.
