Question

(b) There are 40 students in a class. If the number of boys is 10 more than that of girls, find the number of boys and girls.​

Answer 1

Boys are 25

Girls are 15

Explanation:

Total class population = 40

Let girls population = g

Then, boys population = (10+g)

Boys + Girls = 40

`{ \sf{(10 + g) + g = 40}} \\ { \sf{2g = 30}} \\ { \sf{g = 15}}`

Girls = 15

Boys = (10 + g) = (10 + 15) = 25
