The population of the town increased by 2.5% annually but decreased by 0.5 % every, year due to migration. What will be the percentage increased in 2 years?
- 5.04
- 4.04
- 3.04
- none
Explanation
Net percentage increase in Population = (2.5 - 0.5) = 2% each year.
Let the Original Population of the town be 100.
Population of Town after 1 year = (100 + 2% of 100) = 102.
Population of the town after 2nd year = (102 + 2% of 102 ) = 104.04
Now, % increase in population = 4.04 / 100 ×100 = 4.04%
