224、 是一道说医生年龄的题目,OG上的好像,我记得做过,就是说提早十年工作是年龄的1/3?退后十年是2/3的那个?大概是这样的。
How many years did Dr. J live?
1. If Dr. J had become a doctor 10 years earlier than he did, he would have been a doctor for exactly 2/3 of his life.
2. If Dr. J had become a doctor 10 years later than he did, he would have been a doctor for exactly 1/3 of his life.
