This is very simple. Everyone is the same peach, and it's not even 100. According to the meaning of the question, find 100 plus a common multiple of 3, 4 and 5, that is 3x4x5+ 1=6 1. Except this number, there is no other number within 100 that can be divisible by 3, 4 and 5. So no one picked 6 1 peaches.
