Question

⦁ In a class of 25 children there are 10 girls. What percentage of the class are girls and what percentage are boys?

Answer 1

Girls ---> 40% Boys ----> 60%

Explanation:

It is given 10 are girls, which logically implies, 15 are boys.

Now given that the total number of children in the class is 25,

Percentage of girls = 10/25 x 100 = 40%

You could do the same for boys by doing 15/25 x 100, or use some logic and realise that two sets should have a percentage of 100, therefore the percentage of boys in the class is 60%
