The ratio of boys and girls in a school is 5 : 3. If there are 115 boys, find the number of girls in the school.

Given, the ratio of boys and girls in a school = 5 : 3

Also, the total number of boys = 115

Let the total number of girls in the school be x.

Now, ratio of boys and girls in a school must be equal to ratio of their actual numbers

Hence, there are total 69 girls in the school.

  • 1

 115:69
