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

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

2) Of this year's graduating students, 25 percent transferred from another college.

From 1 we get
30/100*m + 20/100*f are transfer student!! So what!! GIVE ME MORE!

where m is no of all males in this year grad batch and f is no of all females

From 2 we get
25/100*(f+m) = transfer stidents

Thus combining,

we get relationship of m:f

Thus we can get m:total!

Hence C

Agree with C

From C, we can find out that m = 0.625f, from this, we can calculate m / (m+f)
