Answer 2

There are 900 boys

Step-by-step explanation:

We are given that 45% of the students in a school are boys

So, percentage of girls = 100% - 45% = 55%

Let the total no. of students in school be x

So, No. of girls = $55\%x = 0.55x$

We are given that number of girls is 1100

So, $0.55x=1100\\x=\frac{1100}{0.55}\\x=2000$

No. of boys = 2000-1100 = 900

Hence There are 900 boys
