Let the no. be x
Boys - 5x
Girls - 3x
EQUATION FORMED IS
5x=3x+10
5x=3x+105x-3x=10
5x=3x+105x-3x=102x=10
5x=3x+105x-3x=102x=10x=10÷2
5x=3x+105x-3x=102x=10x=10÷2x=5
5x=3x+105x-3x=102x=10x=10÷2x=5 so girls =3x i.e 3×5=15
5x=3x+105x-3x=102x=10x=10÷2x=5 so girls =3x i.e 3×5=15boys =5x i.e 5×5=25
5x=3x+105x-3x=102x=10x=10÷2x=5 so girls =3x i.e 3×5=15boys =5x i.e 5×5=25 total students = 15+25
5x=3x+105x-3x=102x=10x=10÷2x=5 so girls =3x i.e 3×5=15boys =5x i.e 5×5=25 total students = 15+25Ans : 40 students
