Question

In a class, 60% of the students are girls and there
are 20 boys. What is the strength of the class?​

Answer 1

Answer:

Girls in the class-60%

Boys= 20

Percentage of boys=Total Strength-Strength of Girls

% boys= 100%-60%=40%

20 boys make up 40% of the total strength of the class

So Every 2% means one student.

Dividing 100 by 2 we get 50.

So, there are 50 students in the class

Answer 2

20×60/100

= 12 % are the boys

total no of girls and boys - 60+12---72

strength of the class -- 100-72 ----28
