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?

Options

• 48

• 44

• 42

• 40

Answer 1

B = 3G.
Total strength = B + G = 3G + G = 4G.
The total strength has to be a multiple of 4.
Therefore, 42 cannot be the total number of children in the class.
