Answer 2

Answer: 80% - 32 boys

Step-by-step explanation:

Given, In class of 40 students 20% are girls.

20% of 40 = (20/100) (40)

                 = 2 x 4

Number of girls = 2 x 4 = 8

Percentage of boys = Total percentage of students - Percentage of girls

                                 = 100% - 20%

Percentage of boys = 80%

80% of 40 =  (80/100) (40)    

                  =  8 x 4

                  = 32

Number of boys = 32
