The total contribution amount is Rs. 1600. Find the number of boy students in the class? let the number of girls be x . Number of boys will be 60-x . Contribution by boys = (60-x)*x contribution by girls = x*(60-x) x(60-x) +x(60-x)= 1600 60x-x^2 +60x-x^2= 1600 -2x^2+120x-1600=0 -2(x^2-60x+800)=0 -2(x^2-40x-20x+800)=0 -2(x-40)(x-20)=0 X= 20 oR 40 NUMBER OF BOYS CAN BE 20 or 40
