Question

In a town of 2,00,000 citizens, if the population increases at the rate of 4% per annum, then what will be the population of the town in 2 years from now? (a) 2,10,000 (b) 3,55,555 (c) 1,84,320 (d) 2,16,000 (e) 2,16,320

Answer 1

Answer:

The correct Option is (e) 216320

Step-by-step explanation:

Initial population = 200000

Population after 1 year :

P(1) = Initial population + Increase in population

      = 200000 + 4% of 200000

      = 200000 + 0.04 × 200000

      = 200000 + 8000

      = 208000

Population after 2 years :

Initial population = Population after 1 year = 208000

Now, Population after 2 year = Population after 1 year + Increase in population

P(2) = 208000 + 4% of 208000

       = 208000 + 0.04 × 208000

       = 208000 + 8320

       = 216320

Hence, the population of the town after 2 years from now = 216320

And the correct Option is (e). 216320
