draw a table: male/female, business major/not business major
we are looking for the number of females
1: 2/5 of females are business major -> insufficient (proportions are not enough)
2: 200 of females are business major -> insufficient (doesn't give info about females who are not business major)
1&2: sufficient -> total number of females is 500 -> C

Let's call C the total number of students in college C, M the number of male students, F the number of female students, B the number of business majors and O the number of other majors.
By definition of M,F,B and O we have C = M + F = B + O
We also know that B = 2/5 C
(1) and (2) gives us B = 2/5 M + 200 so 2/5 C = 2/5 M +200
i.e. C - M = F = 5/2 * 200 = 500
Answer is (C)
