Question

Answer 1

Answer:

720

Step-by-step explanation:

Let the number of girls be x

Given, that number of boys are 160 more than girls

So, no. of boys = 160 + x

Total students = 160 + x + x

= 160 + 2x

Now, it is given that, there are 45% of girls in school

So, 45% (160 + 2x) = x

45/100 (160 + 2x) = x

7200 + 90x = 100x

7200 = 10x

720 = x

x = 720
