If the number of boys in a class are 8 times the number of girls, which value can be the total number of students? Choose the correct choice from the following options:
A) A - 42
B) B - 45
C) C - 41
D) D - 40
E) E - 39
Let the number of girls = x and the number of boys = 8x Then, total number of students = x + 8x = 9x i.e., the total number of students must be a multiple of 9 From the given choices, only 45 cannot be a multiple of 9. Hence, 45 is the total number of students. Answer is B - 45.
