Question

. Green City School has 2,400 students. 45% of them are girls. How many boys are there in the school?​

Answer 1

First of all, let’s assume that there are only 2 genders (boys & girls). Otherwise, we do not have enough information to answer the question.

Let B symbolise the % of boys in the school.

B + 45% = 100%

B = 100% – 45% = 55%

Number of boys

= 55% * 2400

= 55 * (1/100) * 2400 (Remember that % is simply the symbol for 1/100)

= 55 * 24

= 1320
