Question

10. In a school, there are 120 girls. If the number of boys is 3/5 of the total number of children, find the number of boys.
​

Answer 1

Answer:

Given,

the total no. of girls = 120

Let,

Total no.of boys =x

Total no. of children = 120+x

Then,

x=(120+x)3/5

5x=360+3x

2x=360

x=180

therefore, total no. of boys = 180
