The question seems slightly ambiguous to me:

When it says " There are 400 Women at College X and 200 students live offcampus" .. does the 'women' imply only female students or possibly, female teachers or other staff inclusive.

If i think in this line, i get the answer as E.

However, if by 'women' the question implies female students, and 'men' imply only male students (not teachers, staff etc): then here is a different solution:

A. 120 women and 80 men students live offcampus. : no data about men living on campus. insufficient

B. can solve the problem : (no of men in college) = 1/2 * (400 + no of men in college)

By this logic: B is sufficent.

I agree with Target 780. I mean the question is really not clear. Concerning the potential flaw, I agree about "women" and "students".

Here's how you work it out...

Code:
Women               Men             Total

Off Campus                                           200

On Campus                                             x

Total             400                 x/2

400 + x/2 = 200 + x
