Question

in a school 4/9 of the students are boy and the number of girls is 775. find the number of boys in the school

Answer 1

620 boys is the answer

Answer 2

let's take the number of students be 900x. number of boys =4/9(900x)=400x and thus number of girls =900x-400x=500x. 500x is given 775 so x=775/500=1.55 .Number of boys =400x=400(1.55)
=620. Hope it helps you...
