Question

If 60 present of the students in a school are boys and the girls number is 821,how many boys are there?

Answer 1

Answer:

1231.5

Step-by-step explanation:

60% of total students are boys.

So, 40% of total students are girls.

Also, given that number of girls in the school is 821.

Let the school has n number of students.

So, 40% of n = 821

Simplifying the percentage , we get

$\frac{40}{100} \times <strong>n</strong> = 821$

solving for n , we get n = $\frac{(821) \times (100)}{40}$

or n = 2052.5

So, number of boys = total students -number of girls

                                 = 2052.5  - 821

                                  = 1231.5
