Answer 2

Answer:

Population after 3 years=92610.

Step-by-step explanation:

Since The population of city at present is 80000.

It increases by 5% per year.

We need to find the Population after three years.

So, Population after one year=$\dfrac{80000\times 5}{100}=4000$

So, population after one year=80000+4000=84000

So, Population after second year=$\dfrac{84000\times 5}{100}=4200$

So, population after second year=84000+4200=88200

So, Population after third year=$\dfrac{88200\times 5}{100}=4410$

So, population after third year=88200+4410=92610.

Population after 3 years=92610.
