Answer:

After 3 years the population of the town will be 9261.

Step-by-step explanation:

Since, it is stated that the population of the city gets increased at a rate of 5% per year than that of the previous year.

So, it can be calculated by using the formula of compound interest.

It is mentioned that,

Present population = 8000

Increasing rate = 5%

Time = 3 years

∴ Total number of population after 3 years_

$8000*(1+\frac{5}{100})^{3} \\$

⇒ 8000* $\frac{105}{100}*\frac{105}{100} *\frac{105}{100}$

⇒(8*105*105*105)/1000

⇒9261000/1000

⇒ 9261

So, after 3 years the population of the town will be 9261.
