Question

The population of a village is 1,20,000. If the population increases by 5% every year, what will it be after 3 years?


Solution

Population of the village, P = 1, 20,000
Rate of increase in population (R) = 5% p.a.
Number of years (N) = 3 years
Population after three years =P1+R100N
                                            = 1200001+51003= 1200001+1203= 12000021203= 120000×2120×2120×2120= 138915
