Answer 2

No. of students = 88

Amount donated by girls = y = 1936 Rs

Amount donated by boys = 3y = 5808 Rs

•let No. of students be x

•Amount donated by each student =

x

•total donation = No. of students ×

Amount donated by each student

•total donation = x²

•x² = 7744

•x = √7744

•x = 88

•No. of students = 88

•Now, No. of girls : No. of boys = 1:3

•let amount donated by girls be y

•amount donated by boys = 3y

•y+3y = 7744

•4y = 7744

•y =1936

•Amount donated by girls = y = 1936

•Amount donated by boys = 3y =

5808
