The number of boys in a class is three times the number of girls. Which one of the following numbers cannot represent the total number of children in the class ?

[A].

48

[B].

44

[C].

42

[D].

40

Answer: Option C

Explanation:

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

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

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

This is wrong right answer is 48.
4x = 3x+x.
48 = 3(12)+12.
