if the drama club and music club are combined, what percent of the combined membership will be male?
1 of the 16 member of the drama club, 15 are male
2 of the 20 member of the musica club, 10 are male
怎么看都是C 啊。。。为什么选E?

因为你不知道combined membersh后的总人数啊。
题中问的是percent of the combined membership will be male,不是问的人数。
没说drama club的 male都不在music club里
题目应该给的是合并前的数吧?
意思是:16个drama club的会员中,15个是MALE,但未说drama club的总数是多少。
意思是:20个musica club的会员中,10个是MALE,但未说musica club的总数是多少。
此题若改成如下说法的话:
1、of the drama club, 15 are male
2、of the musica club, 10 are male
那么你的理解和算法就正确了。
谢谢,:)
