Half of the no. of boys class 8th B went to the football ground to play. one fourth of the numbers of boys went to the library to take books remaining 10 boys went to the 3rd language room find the no. of boys of class 8th B?

Let the total no. of boys be x

No. of boys went to ground = x/2

No. of boys went to library = x/4

No. of boys went to 3rd language room = 10

Therefore, x - (x/2 + x/4) = 10

= x - 3x/4 = 10

= x/4 = 10

= x = 10 X 4 = 40

Therefore, total boys in 8B is 40.
