A senior executive of a public sector company recently quit his job under the VRS with a hefty packet of INR 1 Crore. Ms. Dhana-chor Chit Fund Company has offered the following investment scheme for the benefit of such retired people: "Invest a certain sum (in lakhs of rupees) in any month; invest half of that amount in the next month. In the subsequent month, one would get twice the amount invested originally in the first month”. This scheme is available only for the next six months (Encashment is possible on 181st day). Returns received at the end of any month can be used immediately for reinvesting either as a fresh investment or as a follow-up investment. Develop a mathematical model to optimize the investment strategy.
INR stands for Indian Rupees
So, In India, They use concept of Lakhs and Crores instead of Millions and Billions.
For Understanding
1 Million = 10 Lakh
1 Billion = 100 Crores
1 Crore = 100 Lakh
and Investment is to be done in lakhs
So all figures onwards are in lakhs
Let Y(t) = Investment on the 0th,30th, 60th, 90th, 120th 150th day respectively (where t = 1,2,3,4,5)
Now, the cash outflow on 0th,30th, 60th, 90th, 120th-day shall not exceed cash in hand
Now Moving forward to Day 180 on which we have to maximize the investments.
Mathematical model to maximize the Investment strategy:
