Question

In a town, where the population is $90,000$, the male population is two-thirds the female population. Find the male and female population of the town.

Answer 1

Total population$=90000$

$m=\frac{2}{3}f$

$m+f=90,000\Rightarrow \frac{2}{3}f+f=90000$

$\Rightarrow 5f=270000$

$\therefore 6=54000$

$m=\frac{2}{3}\times 54000=36000$.
