Decision making criteria: 5).If mutually exclusive following projects (A and B) with normal cash flows are being analysed, the net present value (NPV) and internal rate of return (IRR) methods agree. If the weighted average cost of capital (WACC)/discounted cash flow for each project is 18%, do the NPV and IRR methods agree or conflict? Please note the given, WACC @ 18\% can be taken as discounting factor. Also note that whenever a person taking a capital budgeting decision, NPV (Net Present Value) method and IRR (Internal Rate of Return) method are commonly used methods for evaluating various investing options.
