`If the number of boys in a class is 8 times the number of girls, which value can never be the total number of students?`

A. 27

B. 42

C. 45

D. 81

**Answer: B. 42**

**Solution:**

Let number of girls = x

number of boys = 8x

Then, total number of students = x + 8x = 9x

i.e., total number of students must be a multiple of 9.

In the given choices, 42 is not a multiple of 9.

Hence, total number of students cannot be 42.

Hence, **The Answer is 42.**
