Question

What is the weight of a white ball?

Accepted Answer

First, look at the small scale on the right where 3 pink balls balance a weight of 90, so we divide by 3 (90 / 3 = 30) to find each pink ball weighs 30. Next, because that sub-scale hangs from the main scale, both sides add together (90 + 90 = 180) for a total weight of 180. On the left side, two white balls plus one pink ball (30) equal 180, written as 2 White + 30 = 180. Then, we subtract the pink ball's weight from the total (180 - 30 = 150) to get the weight of the two white balls. Finally, we divide by 2 (150 / 2 = 75) so a single white ball weighs 75.
