The number of boys in the class is three times that of girls, which one of the following numbers can’t be represented?

A) 48

B) 44

C) 42✓

D) 40


Let a number of girls = x, and a number of boys = 3x.

Then, 3x + x = 4x = total number of students.

Thus, to find the exact value of x, the total number of students must be divisible by 4.
