If the ratio of boys to girls is 11:9 and there are 124 more boys than girls:

Let's say that the number of boys is 11x and the number of girls is 9x.

So, 11x = 9x + 124

2x = 124

x = 62

The total number of students = Number of boys + number of girls

= 11x + 9x

= 20x

= 1240 students

Thus, the total number of students attending the school is 1240.
