Question

The ratio of males and females in the population of a town in m:n . Find the percentage of females in the population.. ​

Answer 1

Answer:

The answer will be $\frac{100n}{m+n} %$ %.

Step-by-step explanation:

We have given the ratio of male and female i,e. m:n.

Let the number of female will be y.

Hence, the female in the population n*y.

Hence, the number of men in the population will also become m*y

Now total number of people in the town  will be;

                          ⇒ ny + my;

Now percentage of total female in the population will be given as;

                         ⇒ x/100 * ny + my = total no of population  i,e. ny           (here, x is the percentage of female)

Hence               ⇒x = (ny * 100)/ny+my

                         ⇒x= 100ny/ny+my

                        ⇒ x = (100n)y / (m+n)y

Here, y will over,

thus,              ⇒ x = $\frac{100n}{m+n} %$ %.

That's all.
