What will be the difference in population between 3 years ago and 2 years ago in a town whose current population is 110,000 and which is increasing at a rate of 25% every year?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1, i.e., 14080.
Population 1 year ago = 110,000 × 100/125 = 88,000
Population 2 years ago = 88,000 × 100/125 = 70,400
Population 3 years ago = 70,400 × 100/125 = 56,320
Difference between 3 years ago and 2 years ago = 70,400 − 56,320 = 14,080
