滥竽充数

John says that both he (John) and his friend, Sam, are in their twenties, and that he is five times as old as Sam was when he (John) was three times the age he was when he was twice as old as Sam. How old are they?

a 21 & 22       b 22 & 23       c 23 & 24        d 24 & 25       e 25 & 26



英文不好, 实在被绕晕了, 请高手翻译一下中文, 谢谢!

试着帮你意译一下哈。

john说他和他的朋友sam都是20多岁。

他（john）现在的年龄是sam若干年前年龄的5倍。

在那一年，他（john）的年龄又是自己几年前年龄的3倍。

那年，他的年龄正好是sam年龄的2倍。

我自己也快被绕晕了。
