Suppose your firm is considering two mutually exclusive, required projects with the cash flows shown below. The required rate of return on projects of both of their risk class is 12 percent, and that the maximum allowable payback and discounted payback statistic for the projects are 2 and 3 years, respectively.

Time: 0 1 2 3
