Question

The annual increase in the population of a town is 10%. If the present population of the town is 180,000, then what will be its population after two years ?

• A. 200,000
• B. 210,000
• C. 217,800
• D. 207,800

Answer 1

The correct option is C 217,800

Population after 1 year $=180000+180000\times \frac{10}{100}=198000$

Population after 2 years $=198000+198000\times \frac{10}{100}$

$=217800$
