Question

In a school 720 are boys and 40% are girls, then the number of girls is _____.

Answer 1

Step-by-step explanation:

no of boys= 720

no of girls=?

% of girls= 40%

% of boys= 100%-40%

                 = 60%

Let the total no of students be x

60% of x= 720

60/100x = 720

x = 720*100/60

x = 1200

No of girls = 1200-720

                  = 480
