PREP一道数学的疑惑

sherilynchi

If the drama club and music club are combined, what percent of the combined membership will be male?
(1)  Of the 16 members of the drama club, 15 are male.
(2)  Of the 20 members of the music club, 10 are male.

解题思路：(1) 只給了drama club 裡其中的會員有 16人,而這16人裡有 15人是male, 推得 1位是女的,但是沒              給drama club 總共會員人數, insufficient
              (2)也是同樣的道理, insufficient
              (1)+ (2)仍然無法知道總共會員人數,無法知道percent of the combined membership will be male, insufficient


解题思路我看不太明白，他为什么会说drama club其中的16人，应该是drama club总共有16人吧？难道是我对于of the 16 members...的理解有偏差？

A person can be member of both clubs at the same time.

题目具体说了哪个CLUB的了，因此就不会是both club the same time了
