Question : 14

Total: 40

Solution:

Concept:

Forming a linear equation from the given relation between males and females.

Explanation:

Let the number of males be

x

Females are 7 more than males, so number of females

= x + 7

Total attendance is 23, hence:

x + (x + 7) = 23

2x + 7 = 23

2x = 23 - 7

2x = 16

Divide both sides by 2:

x = 8

Thus, the number of males is 8.
