Consider the following two mutually exclusive projects, X and Y, and their cash flows information Cach Flowro (a) Assume that the appropriate discount rate is 14%, calculate the Payback Period, the Modified IRR (McKinsey's approach) AND the Profitability Index for Project Y. State clearly the key piece of information that you need in order to make the correct investment recommendation on the two projects according to the Payback Period method. (b) Given that Project X's IRR is 15.16%, which project should be chosen according to the IRR method? Precisely explain how you should construct the incremental project and its cash flows numerically. Precisely explain your final selection between these two mutually exclusive projects according to the incremental project (IRR) analysis
