Year 4 Q4. X ltd is considering investing in projects A, B and C. The forecasted cash flows are as follows. project A project B Project C Cash flows(K) cash flows(K) Cash flows(K) 0 (15,000) (17500) (11000) 2500 5000 3000 2 4000 1500 2600 3 1500 6000 5000 3000 2000 1900 5 7000 6500 700 The investment will require a working capital of K2800 for project A and C, and K3200 for project B. The investment will attract a 25% depreciation on reducing balance for project A and C, and straight line allowance for project B. All the projects will have a salvage value of 5000 each at the end expected lifetime. The tax rate is 30% on profits and that the cost of capital is 10%. The lifetime expected is 5 years for all the projects. Calculate the following (a) The payback period for each project (b) The discounted payback period for each project (c) The ARR for each project (d) The NPV for each project (e) The IRR for each project (1) The PI for each project (g)And make an investment decision by suggesting which project to invest in and give reason.
