The population of a town is 2,900. It grows by 10% every year. What will the population be after 2 years?
A. 3,509✓ Correct Answer
B. 3,538
C. 3,190
D. 3,480
💡 Solution & Explanation
Each year's growth is on the new population. After 1 year: 2,900 × 110/100 = 3,190. After 2 years: 3,190 × 110/100 = 3,509. Adding 20% of the original once gives 3,480, which forgets the growth on the first year's increase.
