Question

At a school the ratio of boys to girls is 11 : 9

There are 124 more boys than girls.
Work out the total number of students at the school.

Answer 1

1240

Explanation:

Total boys : Total Girls

= 11x : 9x

9x + 124 = 11x

124 = 2x

x = 62

11x = 11 x 62 = 682

9x = 9 x 62 = 558

Total number of students = 682 + 558 = 1240
