The population of a town is 3,650. It grows by 20% every year. What will the population be after 2 years?
A. 4,380
B. 5,110
C. 5,292.5
D. 5,256✓ Correct Answer
💡 Solution & Explanation
Each year's growth is on the new population. After 1 year: 3,650 × 120/100 = 4,380. After 2 years: 4,380 × 120/100 = 5,256. Adding 40% of the original once gives 5,110, which forgets the growth on the first year's increase.
