no of girls = 100%-70%=30%
therefore,
30/100 of X = 504
30/100 * X = 504
30 *X = 504*100
30*x =50400
X=50400/30
X=1680
so, total number of students in school =1680
no of boys in school =no of total students - no of girls
=1680-504
=1176
therefore,
30/100 of X = 504
30/100 * X = 504
30 *X = 504*100
30*x =50400
X=50400/30
X=1680
so, total number of students in school =1680
no of boys in school =no of total students - no of girls
=1680-504
=1176
