Question

in a class of 120 , 20% are the boys find the number of boys and girls in the class​

Answer 1

Answer:

No. of boys  = 24

No. of girls  =  96

Step-by-step explanation:

No. of students = 120

Percent of boys = 20%

∴ Percent of girls = (100 - 20)%

                             = 80%

No. of boys =  20% of 120

                   = 20/100 × 120

                   = 24

No. of girls = 80% of 100

                   = 80/100 × 100

                   = 96

Therefore, the no. of boys = 24

                  the no. of girls = 96
