Answer 2

hlo mate here's your answer

Let the number of boys be A

Total number of students given = 288

So

Number of girls = 288 - A

So

A/ 288 - A = 7/5

5A = 7 (288-A

5A = 2016 - 7A

12 A = 2016

A = 168

So, Number of girls = 288 - A = 288 - 168 = 120

Now, if more 48 then number of girls = 120 + 48 = 16

So, now the ratio of boys : girls = 168/168 = 1: 1
