Question
The population of a city decreased from 25000 to 24500. Find the percentage decrease.
✓
Answer
Initial population of the city = 25000
Decreased population of the city = 24500
Thus, decrease in population = 25000 - 24500 = 500
$\therefore$ Percentage decrease in population
$=\left(\frac{\text { Decrease in population }}{\text { Initial population }} \times 100\right) \%$
$=\left(\frac{500}{25000} \times 100\right) \%=\left(\frac{50}{25}\right) \%=2 \%$
Hence, the percentage decrease in population is 2%.
Decreased population of the city = 24500
Thus, decrease in population = 25000 - 24500 = 500
$\therefore$ Percentage decrease in population
$=\left(\frac{\text { Decrease in population }}{\text { Initial population }} \times 100\right) \%$
$=\left(\frac{500}{25000} \times 100\right) \%=\left(\frac{50}{25}\right) \%=2 \%$
Hence, the percentage decrease in population is 2%.
