Answer 2

Step-by-step explanation:

Total number of students = 50

Percentage of girls in class = 40%

So, the number of girls in class = 40% of 50

= [40/100] × 50

= 20

Total number of class = No. of girls + No.of boys

50 = 20 + x

x = 50 - 20

x = 30

Total number of girls = 20

Total number of boys = 30
