a. Find the payback period, discounted payback period, IRR, and NPV for each of the three projects.
b. Use the payback period to evaluate options A and B. Which would you choose according to this method? Why does payback period give the wrong answer?
c. Suppose projects A and C are mutually exclusive. Use the IRR to establish which of the two you should undertake. Why does IRR give the wrong answer?
d. Determine whether Project A or C should be undertaken using incremental IRR.
