Answer:
15 boys.
Step-by-step explanation:
A class constituting of boys and girls:
Has a total of 35 students.
The number of girls outnumber that of boys by 5.
Let the number of boys be x such that the number of girls is x + 5.
∴
x + x + 5 = 35
2x + 5 = 35
2x = 35 - 5 = 30
x = 30/2 = 15
So there are 15 boys and 35 - 15 = 20 girls.
