Question

If 70%of the students in a school are boys and the number of girls is 540 find the number of boys in the school ​

Answer 1

Answer:

If 70% were boys

so, 100-70=30%

therefore , 30 %were girls

so , 30% of x = 540

   =30/100*x=540

   =x = 1800

Therefore , there are 1800 total students

so , Number of boys = Total students-number of girls

                                  =1800-540

                                  =1260

Therefore , number of boys are 1260
