Question

Out of 50 children in the class, 20 are boys . Then what is the percentage of girls in the class

Answer 1

Given,

Total children in a class = 50

Total number of boys = 20

To find,

The percentage of girls in the class.

Solution,

We can simply solve this mathematical problem using the following process:

Number of girls in the class

= Total children in a class - total number of boys

= 50 - 20

= 30

Now, the percentage of girls in the class is

= (Number of girls in the class / Total children in a

class) x 100

= (30/50) x 100

= 60%

Hence, the total percentage of girls in the class is 60%.
