The number of students in the school is 1240

How to find the total number

According to the given information, there are 124 more boys than girls. So, we can set up an equation:

Let's denote the number of boys as 11x and

the number of girls as 9x

11x = 9x + 124

11x - 9x = 124

2x = 124

x = 62

Solve for number of boys and girls

Number of boys = 11 * 62 = 682

Number of girls = 9 * 62 = 558

The total number of students

= Number of boys + Number of girls

= 682 + 558 = 1240

there are 1240 students in the school
