The answer 1 earned 2 yuan. Suppose this person has enough money in his pocket, trades twice, 8 in and 9 out,/kloc-0 in,1/kloc-0 out, and makes a profit. When solving math problems.

BMW won't hire you.

Answer 2 earned 1 yuan. Buy 8 and sell 9, earn 1 yuan, repurchase 10, that is, sell 9, repurchase 10, lose 1, sell 1 1, earn 1.

Answer 3: The chicken that could have been bought for 8 yuan was bought at 10, and lost two pieces; We could have 1 1 sold it, but we sold it on the 9th, and we lost 2, making a total loss of 4. Plus 2 yuan, who earned before, lost 2 yuan in total.

From the perspective of general economics, BMW will hire people who answer the third question.
