$\mapsto$ Here it is given in the question that the population of a city decreased from 25,000 to 24,500. Now the question has asked us to find out the deceased percentage of the population of the city. So, to find out the decreased percentage we first need to subtract the original population from the decreased population. The we have to apply the formula in order to get the decrease percentage.

ANSWER:-

$\hookrightarrow$ The decreased percentage is 2%.

GIVEN:-

➤ Original population = 25,000

➤ Population decreased by = 24,500

TO FIND:-

➤ We have to find the decreased percentage.

FORMULA:-

• Percentage = Population decreased / Original population × 100

SOLVING BY APPLYING THE FORMULA:-

• Finding the decreased population:-

➤ Decreased population = Initial Population - Final Population

➤ Decreased population = 25,000 - 24,500

➤ Decreased population = 25,000 - 24,500 = 500

➤ Decreased population = 500

The decreased population is 500.

• Finding the decreased percentage:-

➤ Percentage = Population decreased / Original population × 100

➤ Decreased percentage = 500 / 25,000 × 100

➤ Decreased percentage = 500 × 100 / 25,000

➤ Decreased percentage = 50,000 / 25,000

➤ Decreased percentage = 50,000 / 25,000 = 2

➤ Decreased percentage = 2%

Thus, we got the answer. The decreased percentage is 2%.
