SOLUTION

What percent of the drama club members enrolled at a certain school are female students?

(1) Of the female students enrolled at the school, 40 percent are members of the drama club. 0.4F are members of the drama club. Not sufficient.

(2) Of the male students enrolled at the school, 25 percent are members of the drama club. 0.25M are members of the drama club. Not sufficient.

(1)+(2) We need to find the vale of \frac{0.4F}{0.4F+0.25M}, which, as we can see, cannot be determined with the information provided.

Answer: E.

Tricky one. Level 650.

Stmt 1: Tells us about the percentage of female in drama club but does not talk about specific numbers. Not sufficient.
Stmt 2: Tells us about the percentage of male in drama club but does not talk about specific numbers. Not sufficient.

Together also no additional information is provided. Depending on absolute numbers of female or male students, the percentage of female students at drama club will vary.

Answer: E

Not sure about a 650 level. More like 550. Almost 80% answered correctly. I would assume something in the 650 range would have around a 50% success rate.
