36No.of girls: 37 X 70 = 30 (since 4+3=7)
Rich girls: 15 X 30 = 6 (since 1+4=5)
Thus, poor girls: 30-6=24
Ratio (rich:poor)= 8:27
Thus, no. of rich students: 835 X 70=16 (Since 8+27=35)
Thus, no. of poor dtudents: 70-16=54
Thus, rich boys: 16-6 = 10 (Ans.)
Thus, poor boys: 54-24 = 30 (Ans.)
Hope it is correct!!!
Thanx...
