No C is not right. We cannot assume that there is no overlap between the clubs.

If the drama club and music club is combined, what percent of the combined membership is male?

(1) Of the 16 members of the drama club, 15 are male. Not sufficient.

(2) Of the 20 members of the music club, 10 are male. Not sufficient.

(1)+(2) Since we don't know how many members of the drama club were also the members of the music club then we can not assume that there wasn't any overlap between the clubs and simply write (15+10)/(16+20), so even taken together statements are not sufficient.

One important takeaway here is that questions in GMAT are NEVER that easy, I guess unless you are doing extremely bad in the exam but even then. Always think twice before answering something that seems really easy or "obvious"

Hi All,

DS questions are built to test a variety of skills besides 'math skills', including organization, accuracy, thoroughness, attention-to-detail, ability to see that there is more than one possible answer and the ability to prove that you're correct (when dealing with limited information).

While this prompt looks (and is) relatively simple, it does test the thoroughness of your thinking....

[Reveal] Spoiler:
Does the prompt say that the members of each club are unique? Is it possible that someone could be in BOTH clubs at the same time? And how would THAT impact the math involved?

It's important to consider what the answer to any given DS question could be. In many cases, there is more than just the 'obvious' solution.

GMAT assassins aren't born, they're made,

So you are telling when we encounter such question we should assume overlap even without it explicityly mentioning it?? it is pretty confusing that way.

It's the other way around: we cannot assume that there is no overlap between the clubs.

We don't know the overlap, i.e the number of folks in the drama club, who are also members of the music club and vice versa.
Take this example,
20 members of the music club - 10 are male
all those 10 are also part of the drama club,
total ## of unique members: (16+ 20) - 10 = 26
## of males = 15
so % of males : 15/26 * 100

what if all members were exclusive, ie. no overlap
then % of males : 25/26 * 100

Therefore: E
