Answer 2

Answer:

Hi friends

Step-by-step explanation:

Let the no. of girls be x

We are given that number of boys are 160 more than the girls

So, No. of boys = 160+x

Total students = 160+x+x=160+2x

Now we are given that 45 % girls in the school

So, 45/100(160+2x)=x

7200+90x=100x

7200=10x

x=720

no of girl is 720
