Question

In a class of 60 students the number of girls is one third the number of boys.find the number of girls and boys in this class

Answer 1

Answer:

let number of boys be x

then number of girls = 1/3x

total students = 60

so,

x + 1/3x = 60

4/3x = 60

4x = 60 × 3

x = 180/4

x = 45

therefore

boys = 45

girls = 1/3 ×45 = 15
