Moses Manufacturing is attempting to select the best of three mutually exclusive projects, X, Y and Z. Though all the projects have five-year lives, they possess differing degrees of risk. Project X is in Class V, the highest risk class; project Y is in Class II, the below-average-risk-class; and project Z is in Class III, the average-risk-class. The basic cash flow data for each project and the risk classes and RADRs used by the firm are shown in the following tables. Project X Project Y Project Z | $235,0001.
