Problem 7: NPV versus IRR. Consider the following two mutually exclusive projects: Year Cash flow (X) Cash flow (Y) 0 -9,500 -9,500 1 5,800 3,500 2 4,000 5,000 3 4,000 6,000 7a. The NPV for X is $ _if the required rate of return is 10%. 7a. Points: 1 7b. The NPV for Y is $ Lif the required rate of return is 10%. 7b. Points: 1 7c. The NPV for X is $ Lif the required rate of return is 15%. 7c. Points: 1 7d. The NPV for Y is $ Lif the required rate of return is 15%. 7d. Points: 1 7e. The NPV for X is $ Lif the required rate of return is 24%. 7e. Points: 1 7f. The NPV for Y is $. Lif the required rate of return is 24%. 7f. Points: 1 7g. The cross overrate for these two projects is %. 7g. Points: 4
