The number of Boys in a class is three times the number if girls. Which one of the following number cannot represent the total number of children

Question

The number of Boys in a class three

Answer 1

B = 3G

 

Students = B + G

              = 3G + G

              = 4G

 

Thus the total number of children must be a multiple of 4

 

Answer 2

If there are 3 times as many boys as girls, there are 3 boys for every girl, so 4 children. The total must be a multiple of 4.

 

1028, for example.
