An investor has Rs 10,000 to invest and she has an opportunity to invest the amount in either of two investments A or B, at the beginning of each of the following three years. The investment A results either in a total loss of the amount invested with probability 0.2. The conditions allow at the most one investment each year and she can invest only Rs 10,000 each time and any additional funds accumulated are left idle. Using dynamic programming, find the investment policy that maximizes the expected amount of money will have after three years.
