The population of a town is 18,300. It grows by 10% every year. What will the population be after 2 years?
A. 20,130
B. 22,326
C. 22,143✓ Correct Answer
D. 21,960
💡 Solution & Explanation
Each year's growth is on the new population. After 1 year: 18,300 × 110/100 = 20,130. After 2 years: 20,130 × 110/100 = 22,143. Adding 20% of the original once gives 21,960, which forgets the growth on the first year's increase.
