Question

in a school 25/54students are girls then how and boys are 2030 what is the number of girls in the school

Answer 1

let
total student is x
girl=25x/54
boy=2030 
then,
total student - boy=girl
x-2030=25x/54
x-25x/54=2030
{54x - 25x}/54=2030
29x/54=2030
x={2030*54}/29
x=3780
so, total student=3780
girl=25x/54 ={25*3780}/54=1750
another way, you can also find
girl=3780-2030=1750
