Question

In a school 70% of the students are boys and the number of girls is 600. Find the

strength of the school.​

Answer 1

Answer:

We know that, number of girls is 504. Let the total number of students be x. Then, 30% of x = 504. Therefore, there are 1176 boys in the school.

Step-by-step explanation:

% of  boys + % of girls = 100

            70 + % of girls = 100 

                   % of girls = 30

and, 

number of girls =100%ofgirls× total students 

                  504=10030× total students 

⇒ total students =1680

∴ number of boys = total students − no. of girls

                               =1680−540

                               =1176
