Answer 1

Answer:

The number of boys in school is 1260

Step-by-step explanation:

Boys in school is 70% hence 30% girls are there in school.

Number girls is 540 and let x be the number of boys

For 30%---> 540

For 70%---> x?

Using cross multiplication, we can find the x

$x=\frac{70\times 540}{30} \\x=1260$

The number of boys in school is 1260
