Of the class of 40 students, 20% are girls. how many boys are in the class?
- 26
- 28
- 30
- 32
Explanation
If 20% of the students are girls, then the remaining percentage (100% - 20% = 80%) represents the boys.
So, in a class of 40 students:
80% of 40 = (80/100) * 40 = 0.8 * 40 = 32
Therefore, there are 32 boys in the class.
