Question 3 (10 marks) a) Six mutually exclusive projects A-F are being considered by a company. They have been ordered by first costs so that project A has the lowest first cost, and F the highest. The table below provides information on the IRR and incremental IRR of each investment. For example, the IRR of C is 11 % ; the incremental IRR going from A to C is 13 % and the incremental IRR from B to C is...
2) In the design of a new facility, the mutually exclusive alternatives in the table below are under consideration. Assume that the interest rate (MARR) is 15%. First draw the cash flow diagrams. Then, use the following methods to choose the best of these three feasible alternatives: Alternative 1 Alternative 2 Alternative 3 $ 11 $ 12 $ 13 Investment (first) cost (please see the table for your value) $ A1 $ A2 $ A3 Net cash flow per year...

You are deciding between two mutually exclusive investment opportunities. Both require the same initial investment of $ 10.5 million . Investment A will generate $ 1.92 million per year (starting at the end of the first year) in perpetuity.

A small construction project having a useful life of 5 years has five mutually exclusive alternatives. With an MARR of 6% and using incremental IRR which alternative should be selected? Note: First solve for the IRR for each alternative. You may use a spreadsheet to iterate to solve, but solve for the IRR for Alternative II 'by hand' by iterating between the interest rate tables in the back of the book.
