GMAT Prep2?? (Committee)

Hi dferm,

For statement 1, if 7/12 of the members are women, then 5/12 must be men (since a member must be a man or a woman, anyone who is not a woman must be a man).

For statement 2, originally, 8/13 members of the committee are women. Then, if one woman resigns, we're down to 7/12 are women, which means that 5/12 are men (see statement 1's reasoning).

So, each statement is sufficient by itself, and D is the correct answer.
