Question

if 70% of students in a school are boys and the no of girls is 540 find the no of boys in the school?

Answer 1

Answer:

given ,

70% are boys ...

so remaining i.e, 30% are girls

and

30 % =540 girls

100 %=(540/30)*100=1800 students

so , total students = 1800

No of boys=1800-540=1260

Answer 2

Answer:

1260 boys

Step-by-step explanation:

$30\% \: of \: x = 540$

$\frac{30}{100} \times x = 540$

$x = 540 \times \frac{10}{3}$

$x = 180 \times 10$

$x = 1800$

x= 1800 - 540

x= 1260
