问题 A farmer buys a horse for $ He sells it to his neighbour for $ Then he discovers he could have made a better deal. He borrows $ 10 from his wife, and buys the horse back for $ 80. He then sells it to another neighbour for $ How much money did he make?

选项

答案$10

解析 第一次买马花费$60,卖了$70,共盈利$10。第二次买马花费$80,卖了$90,再除去借妻子的$10,共盈利$0。所以,通过两次对马的买和卖,他共盈利$10。
