(1) 300 (2) 320 (3) 340
(4) 360​

Answer 1

Step-by-step explanation:

Let the no. of students = x

boys = 4x

girls = 3x

total boys = 480

A.T.Q. :-

4x = 480

x = 480/4

x = 120

Therefore, Total no. of girls = 120 * 3

= 360.

Answer 2

Answer:

options ( 4 ) 360

Step-by-step explanation:

Let the ratio be x = 4x and 3x

let boys be 4x

let girls be 3x

Number of total boys = 480

According to question

4x = 480

x = 120

put the value of x = 120 in 3x

3x = 3 ( 120 )

= 360

The number of girls in the school is 360
