The population of a village increased by 10% in the first year and 20% in the second year. What is the total percent increase after 2 years?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 32%.
Assume the initial population = 100
After 1st year:
100 + 10% of 100 = 100 + 10 = 110
After 2nd year:
110 + 20% of 110 = 110 + 22 = 132
Increase in population:
132 − 100 = 32
Therefore, the total percent increase after 2 years is 32%.
