What will be the population of a country after 5 years at an annual increase of 10%?
Population × (1+ 10/100)5
Population × (1 - 10/100)1/5
(Population × 10 × 5)/100
Population × (10/100)5
The given problem demands compound interest:
∴ The formula becomes: Population × [1+10100]5
The population of a town increases 10% annually. If its present population is 60000, what will be its population after 2 years?
