The population of the city decreased from 50,000 to 49,500. Find the percentage decrease in the population.

Given: Initial population of the city = 50,000

Final population of the city = 49,500

Decrease in population = Initial population – Final population

= 50,000 – 49,500

= 500

∴ Percentage decrease in population

$=\left(\frac{\mathrm{Decrease} \mathrm{in} \mathrm{population}}{\mathrm{Initial} \mathrm{Population}}\right)\times 100$

$=\left(\frac{500}{50,000}\right)\times 100$

$=\frac{5}{5}$

$=1\%$

Hence, the percentage decrease in population is 1%.
