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?
Answer: B. 42
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.
