Question

in a school 25/54of the students are girls and the rest are boys.if the no. of boys is 2030.find the no. of girls.

Answer 1

ratio of no of girls =25/54
ratio of no of boys = 1- 25/54
= 29/54
no of boys = 2030
Let the total no of student to be x
so 29/54 of x = 2030
x = 2030 × 54/29
x = 70 × 54
x = 3780
no of girl student = total no. of student - total no of boys
= 》 3780 -2030
=》 1750
so the number of girl student = 1750
