2.4 Use present value analysis to determine which of the following three payment sequences would you prefer if you are to receive payments (in thousands of Rands) at the end of each of the next five years when the nominal interest rate is r=0.5 (provide necessary details): A. 12, 14, 16, 18, 20; B. 16, 16, 15, 15, 15; C. 20, 16, 14, 12,10 . Q.5 Assume that after one time period, the value of a stock (whose present value is R80) would be either R120 or R60. Suppose that, for any y, at a cost of Cy, one can purchase at a time- 0 the option to buy y shares of the stock at time-1 at a price of R90 per share. For what values of C, no-arbitrage will be possible? (Provide necessary details)
