Verified Answer
Two years ago, the population of a village was 62500. If in two years,...
Let the rate of increase be ‘R%’
Population of village two years ago = 62500
Present population of village = 62500 + 24525 = 87025
∵ Population after n years = Population n years ago × (1 + Rate/100)n
Putting n = 2,
⇒ 87025 = 62500 × (1 + R/100)2
⇒ 1.3924 = (1 + R/100)2
⇒ √1.3924 = (1 + R/100)
⇒ 1.18 = 1 + R/100
⇒ R = 0.18 × 100 = 18%
∴ Rate of increase of population per year = 18%
