a) Critically evaluate the net present value (NPV) and the internal rate of return (IRR) investment appraisal methods. (5 marks) b) An engineering organisation has the opportunity to invest in three different projects, A, B and C, which have the following estimated cash flows: i) ii) Year Project A Project B Project C 0 (200,000) (200,000) (200,000) 1 70,000 40,000 40,000 2 70,000 50,000 40,000 3 70,000 70,000 40,000 4 70,000 80,000 200,000 If the organisation has a cost of capital (discount rate) of 10%, calculate the net present value of each project. (See Appendix Q4 for discounting table) (10 marks) The organisation can invest in only one project. As a project engineer, what advice would you offer and why?
