The population of a town first decreased by 16% due to migration to a big city for better job opportunities. The next year, the population of the town increased by 21% as there were better facilities for jobs. What is the net percentage change (correct to 2 decimal places) in the population?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Increase by 1.64%.
Let the initial population of the town = 100
Population after 16% decrease = 100 - 16 = 84
Population after the 21% increase = (121/100) × 84 = 101.64
Increase = 101.64 - 100 = 1.64
Therefore, the net percentage increase in the population is 1.64%.
