c) Define 'population forecasting'. Why we forecast 'population' for the future time for a newly establishing town? Mention different methods of 'population forecasting'. Which method would you recommend as the most rational method for 'population forecasting'. Comment and justify your answer by arguments. Two mathematical formulae as given are P, = P, + K, (t, - t) and InP, = InP, + K, (t, - t) respectively representing the arithmetic and geometric growth methods of 'population forecasting'. Which of these formulae you will correlate with 'Simple Interest Formula' and "Compound Interest Formula'. If you are sure your answers are correct, write down those formulae. Compare, discuss and justify. [2.5)
