Question

The population of a city decreased from $25,000$ to $24,500$. Find the percentage decrease.

Answer 1

Initial population of a city = $25,000$

Current Population of a city = $24,500$

Decrease in population of a city = $25,000-24,500$

= $500$

Percentage decrease in population = $\left(\frac{Decreaseinpopulation}{InitialPopulation}\times 100\right)\%$

= $\left(\frac{500}{2500}\times 100\right)\%$

= $\left(\frac{1}{5}\times 100\right)\%$

= $20\%$

Hence , decrease in population of a city is $20\%.$
