Let the no. of total students be x
no. of girls =240
5/6x +240= x
240 =x - 5/6x
240 =6x^2-5/6x
240 ×6x = 6x^2 -5
1440x = 6x^2 -5
U will get the ans. by solving this equation

Let be the total no. of students be x If boys =5/8 Then. =5x/8+240. =x 5x/8-x =-240 -3x/8. =-240 3x/8. =240 3x. =240×8 x. =240×8/3 x. =640 totale of student. =640-240
=400boys
So,
the number of boys in a school of 400.
