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
