here it goes
From 1 we get:
33/100*m + 20/100*F = Transfered from other college
So what? We do not get anything more from this!
From 2 we get:
25/100*grad students = Transfered
ie total transfered = 25/100*(Total males and females)
But still by itself its useless!
But now equate the two:
we get -
33/100*m + 20/100*f = 25/100*(m+f)
Solve to get all m on the left hand side and all f on the right hand side u will get the ratio of male to females in the school!
9m = 5f
or m/f = 5/9
or m/total = 5/14!
So the percentage of male = 5/14*100!
