What is the present population of town B if the difference between 1 year ago and 2 years ago is 10000 and rate of increase is 20%?

• 72000
  
  Let population before 2 years=x, then before 1 year=1.2x and present population=1.44x
  Difference of population before 1 year and 2 year = 1.2x - x = 10000
  => 0.2x = 10000 or x=50000
  So present population=1.44x=1.44*50000=72000
