Question

At a school number of boys :number of girls = 11:9
There are 124 more boys than girls
Work out the total number of students at the school

Answer 1

Let's represent the number of boys as 11x and the number of girls as 9x, where x is a constant.

According to the problem, 11x - 9x = 124.

Simplifying the equation, we have 2x = 124.

Dividing both sides by 2, we find x = 62.

Now, we can find the total number of students:
Total number of students = Number of boys + Number of girls
= 11x + 9x
= 20x
= 20 * 62
= 1240.

Therefore, the total number of students at the school is 1240.
