The population of a town increases by 20% in the first year, decreases by 10% in the second year, and again increases by 25% in the third year. If the population at the beginning was 40,000, what will it be after 3 years?
Show answer & explanation
Correct answer: D
Explanation
Initial Population = 40,000
Increase in the first year = 20%
Decrease in the second year = 10%
Increase in the third year = 25%
New Population = Old Population × (1 ± Percentage/100)
After the first year = 40,000 × 1.20 = 48,000
After the second year = 48,000 × 0.90 = 43,200
After the third year = 43,200 × 1.25 = 54,000
