Let's do it this way!
1. Last 11 yuan - 8 yuan = 3 yuan
2. Sold for 9 yuan: 9 yuan - 8 yuan = 1 yuan
3. Bought back for 10 yuan: 10 yuan - 8 yuan = 2 yuan (loss of 2 yuan)
4. 3 yuan + 1 yuan - 2 yuan = 2 yuan
Is this correct? I swear I don't know the answer! Is this method correct now?

This is an IBM exam question. If you answered that the profit is 2 yuan, you are definitely a failed interviewee; if you answered 3 yuan, you are even more foolish, because you don't even know what the additional cost is, and you are also definitely a failure; if you answered 1 yuan, congratulations, you are not in the range of fools. The result is: what could have been a direct profit of 3 yuan has, after his three transactions, become a total profit of 1 yuan.
For this transaction, you need to have at least 10 yuan, with the initial value set at 10. So it's 10 - 8 + 9 - 10 + 11 = 12. So you get it, 10 yuan turned into 12 yuan.
