Question

if 70% of of the students in a school are boys nd the number of girl is 540 find the no. of boys in school

Answer 1

Let the total student be x
70% of total= boys
No of boys = 70x /100
No of girls =540
540 +70x/100=x
54000 +70x =100x
54000=30x
X =1800
Total students are 1800
No of boys =1260
