Question

70% of students are boys and the number of girls are​ 504. Find the value of boys in the school.​

Answer 1

Answer:

$\large\bold\red{1176}$

Explanation:

Let the number of students be x

Now,

It's given that,

70% of x are boys.

Therefore,

Girls will be 30% of x.

But,

No. of girls = 504

Therefore,

$= > \frac{30}{100} x = 504 \\ \\ = > x = 504 \times \frac{100}{30} \\ \\ = > x = \frac{504 \times 10}{3} \\ \\ = > x = 168 \times 10 \\ \\ = > x = 1680$

Therefore,

Number of students = 1680

Hence,

Number of boys = (1680 - 504) = 1176
