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 ?
Answer: Option
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.

Yeah, the correct answer is 48. But they asked only what is the wrong answer among the given options, So it's obviously 42 which it can't divisible by 4 directly.

All the number is easily divisible by 4 except C.
So, C is the right answer because in the question they asked which is not represnt the total num of children.

Only 42 is not divisible by 4. So here the answer is option (C).

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