Suppose we give three to each person now, and there is still one in hand.

Now give one to the first little monkey and it will be gone.

If you give another one to the second little monkey, you will be short of one.

If you give another monkey, you will lose two.

At this time, there are three little monkeys, and each one is two or four, which is just right.

So a *** has three little monkeys, each with three left, so A * * * has peaches 3*3+ 1=9.
