The combined ages of a monkey and its mother are 4Years. (Now, take a deep breath ) The mother is twice as old as the monkey was when the mother was half as old as the monkey will be when the monkey is three times as old as its mother was when she was three times as old as the monkey was.
The key point is to find out the age difference (12 months), which is deduced from this sentence:
The mother is (30 months old) twice as old as the monkey was (15 months old) when the mother was (27 months old) half as old as the monkey will be (54 months old) when the monkey is three times as old as its mother was (18 months old) when she was three times as old as the monkey was (6 months old).
哈哈哈哈 O(∩_∩)O哈哈~ 好久不来了，不小心看了一眼自己主页，发现自动关联了自己以往发过的帖，点进这个看了一眼，笑个半死。。。敢情我当初还发过这么搞笑的东西啊，我自己完全不记得了
