The population of a town is 5,425. It grows by 20% every year. What will the population be after 2 years?
A. 7,812✓ Correct Answer
B. 7,866.25
C. 6,510
D. 7,595
💡 Solution & Explanation
Each year's growth is on the new population. After 1 year: 5,425 × 120/100 = 6,510. After 2 years: 6,510 × 120/100 = 7,812. Adding 40% of the original once gives 7,595, which forgets the growth on the first year's increase.
