The number of boys in a class is 20. If 60% of the class are girls, what is the strength of the class?
Given : The percentage of Girls = 60%
The percentage of boys = 100 - 60 = 40%
Let the total number of students in the class be x
40x100 = 20
⇒ x = 50
60% of a class are girls. The number of boys is 20. So, the strength of the class is 45.
In a class, 60% of the students are girls and there are 20 boys. What is the strength of the class?
