以下是引用foreverlovett在2005-8-31 0:06:00的发言：

At a certain university , if 50%of the people who inquire about admission policies actually submit application for admission, what percent of those who submit application for admission enroll in classes at the university?(E)

如果50%打听招生政策的人递交了入学申请，则有百分之多少递交入学申请的人真正到学校中来上课？

(1)Fifteen percent of those who submit applications for admission are accepted at the university.

15%递交入学申请的人被接受入学

(2)Eighty percent of those who are accepted send a deposit to the university.

80%被接受入学的人交了押金给学校。

我不懂这题什么意思,尤其是"enroll in"这个短语,有谁能帮我翻译一下,然后告诉我为什么选E吗??谢谢谢谢了~~~~~~~~~~~~~~~~

enroll in 是参与、注册、入学的意思啊，这题好像有n个层次：

打听招生政策--->递交入学申请--->被接受（被学校同意招生入学）--->交押金--->真正来学校上课...

每个步骤都有一部分人被淘汰，需要n个百分比相乘，才能得到所求答案，两个条件加起来仍不充分，所以E

感觉这题像是在考RC，而不是MATH...没什么太大意思

我没见过这题~所以给你答了~MM还是把题号和来源标在题目上吧~方便后人查找，谢谢了！！

已经很清楚明白了,非常谢谢happyfish~~~~~~~~~~
