Lana71 [14]
I think boys =18
          girls=12
boys :x
girls:y
student:z
the number of group for the boys :n
the numberof group for the girls :m
so x=(3/5)*z
    y=(2/5)* z
x/y=3/2
3y-2x=0
(1/10)*z*n=(3/5) *z
so n=6
(1/5)*z*m=(2/5)* z
put x=(1/10)*z*6
    y=(1/5)*z*2
 into 3y-2x=0 and z=30
 z=30 so x=(1/10)*30*6=18
               y=(1/5)*30*2=12
