Question

ratio of boys and girls in a school is 4 : 3. If there are 480 boys in the school, find the number of girls?

Answer 1

Let the number of girls be x.
4:3::480:x
=> 4x = 480×3
=> x = (480×3)/4
=> x= 360

Answer 2

Solutions :-



We have,

Ratio of boys and girls in a school is 4 : 3

Total number of boys = 480


Find the number of girls :-

Let the number of girls be x

A/q

=> 4/3 = 480/x
=> 4 × x = 480 × 3
=> 4x = 1440
=> x = 1440/4 = 360


Therefore,
Ratio of boys and girls in a school
= 480/360 = 4/3 = 4 : 3



Hence,
The number of girls in a school is 360.
