Question

The number of boys in a class is five more than two times the number of girls in a class. Which of the following cannot be the number of boys in the class? ( A ) 13 ( B ) 15 ( C ) 10 ( D ) 11

Answer 1

Answer:

C) 10

Step-by-step explanation:

Let the number of girls be x .

Number of Boys = 2x + 5.

So substituting values in above equation

When x = 1,  boys = 7

When x = 2 , boys = 9

When x = 3, boys = 11

When x = 4, boys = 13

When x = 5, boys = 15
