Question

The ratio of the number of boys to the number of girls in a school is 14 : 15. There are 27 more girls than boys. How many girls are there in this school? How many boys?


Solution

Let the number of girls in the school be g.

Number of girls in the school is 27 more than the number of boys, therefore, the number of boys in the school is (g 27). 

Ratio of the number of boys to the number of girls = 14:15

(g 27) = 405 − 27 = 378

Thus, the number of girls in the school is 405 and the number of boys in the school is 378.
