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

Answer 1

h

Explanation:

hg

Answer 2

1240

Explanation:

the ratio is 11:9

let the number of girls be x, then the number of boys is x + 124

now

`(x+124)/(x) = (11)/(9)`

9x + 1116 = 11x

2x= 1116

x=558

so total number = x + (x+124) = 1240
