Question

11:9 ratio
boys to girls 124 more boys than girls total amount

Answer 1

Answer:

No. of girls = 558

No. of boys = 682

Step-by-step explanation:

Let the no. of girls be x

Let the no. of boys be y

y = 124 + x

=> y : x  =  11 : 9

=> (124 + x) : x  =  11 : 9

=>  $\frac{(124 + x)}{x}$  =  $\frac{11}{9}$

=> (124 + x ) * 9  =  11x

=> 1116 + 9x  =  11x

=> 1116  =  11x - 9x

=> 1116  =  2x

=> $\frac{1116}{2}$  = x

=> 558 = x

No. of girls = 558

Therefore,  y  = x + 124

                                     = 558 + 124

                 no. of boys = 682

No. of boys : girls = 682 : 558  OR  11:9
