Answer:

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=  

100

30

​  

× total students  

⇒ total students =1680

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

                              =1680−540

                              =1176
