一道GMAT OG上的数学题
Of the 230 single-family homes built in City X last year,how many were occupied at the end of the year?
(1)Of all single-family homes in City X,90 percent were occupied at the end of last year.
(2)A total of 7200 single-family homes in City X were occupied at the end of last year.
为什么答案给的是说着两个条件知道了哪一个都没有办法得出结果阿~
句首的of怎么翻译阿?

of可以解释为在.中
我先把题翻译一下.
在城市X去年建造的230个single-family homes中,有多少个会在年末被占用?
(1)在城市X的所有single-family homes中,90%在年末被占用
(2)城市X中,总共有7200个single-family homes在年末被占用
下面我们来一个一个解答.
(1)我们不知道在那被占用的90%房子里面,有没有部分包含或完全包含去年建造的230个房子.答案是可能包含,也可能不包含.所以条件1没有办法得出结果.
(2)从这个条件我们知道了总共有7200个房子在年末被占用,但是我们依然不知道去年建造的230个房子有没有包含在这7200个房子中.
这里再罗唆一下.其实不论是GRE还是GMAT,它们的数学题都不难的.要解答好,首先要复习好基础知识(多时初中内容),其次是正确理解题意,再加上小心谨慎,获得满分的可能性是很大的.
