10. A person bought a chicken for 8 yuan, sold it for 9 yuan, and then thought it was not worthwhile. He bought it with 10 yuan, and bought another one with 1 1 yuan. How much did he earn?

This is an interview question:

There are three algorithms:

1. At first, there was only 8 yuan, and finally you had 1 1 yuan, so you earned 3 yuan;

2. The first time the protagonist lost 8 pieces, and the second time he got a chicken; The hero gets 9 pieces and loses a chicken; On the third sale, the hero lost 10 and got a chicken. In the fourth transaction, the hero got 1 1, and one chicken was missing, so the total GDP was 8+9+10+1= 38 yuan +4 chickens.

There are three transactions in the whole event. Let's see which three deals are specific.

The first transaction: 8 yuan buys, 9 yuan sells, and gains 1 yuan;

The second transaction: 9 yuan sells, 10 yuan buys, and the profit is-1 yuan;

The third transaction: 10 yuan buys, 1 1 yuan sells for profit 1 yuan;

The whole process:1-1+1=1yuan.

So the analysis shows that this person is a fool, because the last two transactions are equal to nothing.
