Have you solved this tricky weight puzzle? At first glance, the number 90 seems to be the main clue, but there’s an important detail many people overlook.
The small balance on the right is level, with three pink balls on one side and a weight of 90 on the other. This means the pink balls weigh 90 in total, so each pink ball weighs 30.
Now look at the large balance. On the left are two white balls and one pink ball. On the right hangs the entire smaller balance, so we must count the weight on both sides: 90 + 90 = 180.
Since the large balance is level, the two white balls and one pink ball must weigh 180 altogether.
Subtract the pink ball’s weight of 30:
180 − 30 = 150
Divide by two:
150 ÷ 2 = 75
The correct answer is 75. Did you get it right? Share your answer in the comments!
