3. Timing differences: Two mutually-exclusive investment projects have the following forecasted cash flows: Year Om -$200 $ 0 $ 0 +$400 D - $200 +$300 0 0 3 a. Compute the NPV of both projects using a zero percent discount rate. b. Compute the NPV of both projects at an 8 percent cost of capital. c. Based on your answers to parts (b), which project should be adopted? d. Calculate the IRR of both projects to the nearest whole percent. e. Which project should be accepted using the IRR rule? f. What in the incremental IRR to the nearest whole percent? (Hint: your answers to part (d) should give you a fairly good idea of where the incremental IRR is situated) g. Based on you answers above, draw the NPV profiles of both projects. On your graph, be certain to show the NPV-axis and k-axis intercepts as well as the crossover discount rate. Show the area of project evaluation conflict
