Question

55%students in a school are girls. Find the total number of students in the school if 405 are boys

Answer 1

Let the number of total students be x

Percentage of girls=55%

So,percent of boys =100%-55%=45%

Since boys are 405

So 45%of total students =Number of boys

45/100× x=405

x=405×100/45

x=900

So total number of students are 900
