The net cash flow (in thousands of pounds) for two projects, A (fast food) and B (amusement), is as follows: Year Project A Project 1 -5 2 - 10 122 3 - 120 4 130 200 110 B Project A involves an initial outlay of 420,000, and project B involves an initial outlay of 95,000. 148 5 150 Part B Explain how to estimate the IRR using the following two methods: Plotting both NPVs graphs Using algebra and solving appropriate equations. - 50 Part A Use the NPV of each project to decide which project is the most profitable if the discount rate fluctuates between 7% and 8% inclusive. Then, use the IRR of each project to decide which project is the most profitable. You need to provide full explanations and complete steps of your working. You also need to compare and contrast the two methods used in Part A and Part B.
