What fraction of this year's graduating students at a certain college are male?

1) Of this year's graduating students, 33% of the males and 20% of the females trasferred from another college.

2) Of this year's graduating students, 25% transfered from another college

Say there are M males and F females

From eq1: 0.33M males and 0.2F females are transfer students

From eq2: 0.33M+0.2F = 0.25(M+F)

0.08M = 0.05F

so M = 5/13 of graduating students.

C - Both statements sufficient together
