Question

The ratio of boys and girls in school is 9:4. If the total number of boys is 450 then find the total number of girls in the school?

Answer 1

Answer:

200 Girls

Step-by-step explanation:

Let 9x be the no. of boys and,

4x be the no, of girls.

So accordingly,

9x + 4x = Total no. of students in the school.

Since the total number of boys in the school is 450,

we can say that 9x = 450, since the ratio is 9:4.

So,

9x = 450

x = 450/9 = 50

Now since x = 50, we can find out the no. of girls.

So, 4x = No. of girls in the school

Which is nothing but, 4 * 50 = No. of Girls in the school.

Thus, 4 * 50 = 200.

And there are 200 girls in the school. Which is your answer.
