Question

The population of a town increases by $10\%$ every year. If the current population is $15,000$, then what will be the population after two years?

• A. 18,150
• B. 1750
• C. 19,500
• D. 18,000

Answer 1

The correct option is A 18,150

Population after one year
$=15,000+10\%\text{of}15,000=15,000+\frac{10}{100}\times 15,000=15,000+1500=16,500$

Population after two years $=16,500+10\%\text{of}16,500=16,500+\frac{10}{100}\times 16,500=16,500+1650=18,150$
