Answer is B.

Statement 1 -- this is insufficient, because we do not know anything about the percentage breakouts of males or females, or of those who applied to college.

Statement 2: Sufficient. Let m = number of males, and f = number of femals. m+f = T (total student body). We can set up an equation for the perccentage of people who applied to college. (.72m + .8f)/T = .75

.75m + .75f = .72m + .8f

.03m = .05f

The ratio of males to females in this group is given by m/f = 5/3

Now we can find out the fraction of males represented in the total student body, because we know m + f = T. f = 3/5m, so m + 3/5m = T.

8/5m = t

m = 5/8 t

Therefore, males represent 5/8 of the student body.

Makes complete sense now! Thanks

OA is B.
