Question

55% of students in a school are girls. If there are 135 boys, find
the total number of students and the number of girls.

Answer 1

Answer:

Number of girls = 165

Explanation:

First, lets assume the number of girls as x.

= 55:45 :: x:135

= 55x135 = 45x

= 7,425 = 45x

= x = 7425/45

= x = 165

Final Answer: The total number of girls in the school were 165.
