Question

The ratio of male and female in a city is $7:8$ respectively their percentage of children among males and females is $25\%$ and $20\%$ respectively. If the number of adult females is $156800$, what is the total population of the city?

Answer 1

Let the total population be 'p'

Given ratio of male and female in a city is 7:8

In tht percentage of children among male and female is 25% and 20% repeatively.

$\Rightarrow$ Adult male and female % = 75% and 80$

But given adult females = 156,800

$\Rightarrow$ 80% (80/15)=156800

$\Rightarrow$ 80% $\times \frac{80}{15}\times 100=156800$

$\Rightarrow p=\frac{15\times 1568\times 100}{80\times 8}=3,67,500$

$\therefore$ Total population of the city = 3,67,500
