I just took my last gmat prep test before the exam, and guess what, the same question popped up.

At first I was surprised that such an ambiguous question was on gmat prep, which meant that there could be other questions of this type as well.

Then i saw that the question actually says -

"If 4800 voters who voted for or against Resolution K...."

C makes sense now.

As rashminet84 correctly mentioned before, C is the correct OA. I was confused as well untill I saw the hint at the exact wording. Moreover, the short answer explanation given in the software tells us also that B can't be correct and hints in this direction.

Edited the question. Initially crucial part "or against" was omitted.

(1) 3/4 of the Democrats and 2/3 of the Republicans voted for resolution K.

(2) 1/3 of the Democrats who voted for Resolution K and 1/2 of the Republicans who voted for Resolution K were females.

This one is fairly straightforward question. We don't even need matrix/diagram or any calculation.

(1) 3/4 of the Democrats and 2/3 of the Republicans voted for resolution K --> no info about female voters. Not sufficient.

(2) 1/3 of the Democrats who voted for Resolution K and 1/2 of the Republicans who voted for Resolution K were females --> no info about how many Democrats/Republicans voted for. Not sufficient.

(1)+(2) From (1) we know how many Democrats/Republicans voted for and from (2) we know what fraction of each of these group were females, thus we can get exact # of females who voted for. Sufficient.

Answer: C.
