If mutually exclusive projects with normal cash flows are being analyzed, the net present value (NPV) and internal rate of return (IRR) methods always agree. Projects Y and Z are mutually exclusive projects. Their cash flows and NPV profiles are shown as follows. Year Project Y Project Z 0 -$1,500 -$1,500 1 $200 $900 2 $400 $600 3 $600 $300 4 $1,000 $200 NPV (Dollars) 800 600 Project Y 400 Project Z 200 -200 0246 8 10 12 14 16 18 20 COST OF CAPITAL (Percent) If the weighted average cost of capital (WACC) for each project is 14%, do the NPV and IRR methods agree or conflict? O The methods agree. O The methods conflict.
Q3) For a 12% per year MARR, consider the following two investment projects: Project A Project B Year Net Cash Flow, BD Net Cash Flow, BD -2000 -3000 1 1000 1100 2 700 1900 3 1000 1100 4 700 Determine the following: a) Based on Rate of Return analysis (IRR), which project would you select? Why? b) Based on Simple Payback analysis (np), which project would you select? Why? c) Which analysis method is better to use in engineering analysis? Why?
