The current population of the village is approximately 26803 people.
Given,
population of a village 3 years ago = 25000
rate of growth of population = 3%
no. of people who died due to epidemic an year ago = 500
To Find,
the present population of the village
Solution,
We can solve this problem using a simple method.
We have been given that the population of a village 3 years ago is 25000.
We have also been given that the rate of growth of population each year is 3%
This means that 2 years ago, the population was 25000 + 3% of 25000
⇒ 25000 + 750
⇒ 25750 is the population 2 years ago.
Further an year ago, the population was 25750 + 3% of 25750
⇒ 25750 + 0.03 of 25750
⇒ 25750 + 772.5
⇒ 26522.5 is the population an year ago.
But we have been given that 500 people died of epidemic disease.
⇒ The population was 26522.5 - 500 an year ago.
⇒ Hence, the population was 26022.5 - 500 an year ago.
Now, the current year, the population grew 3%
⇒ 26022.5 + 3% of 26022.5
⇒ 26022.5 + 780.675
⇒ 26803.105 is the present population
Hence, the current population of the village is approximately 26803 people.
