28 monkeys live on an island. Some of them are jumping on trees, a few of them are playing on ropes, and the others are resting on the grass. There are a total of 19 monkeys on the trees and on the ropes. I counted a total of 17 of them on the trees and in the grass. How many monkeys are there on the trees, how many on the ropes and how many in the grass?
