7. Given the shortcomings of the IRR methodology, it still proves to be an accurate method to use in evaluating the project alternatives facing IEI. It measures the benefits or returns relative to the amount invested and does not give a fixed dollar amount of return, unlike NPV which is prone to error. IRR also discounts the cash flows unlike the undiscounted payback period.
IRR also proves to be accurate because accdg. To this method, among the investment alternatives of IEI, only (c) or the combined project is acceptable because IRR>cc. This is consistent with the payback and NPV method where only c is acceptable as well.

(a)The undiscounted payback method ranks the alternatives according to which recovers the initial investment fastest (lowest payback period). The alternatives of IEI has payback periods that exceed n. In this case, the project with the smallest remaining unrecovered initial investment is ranked highest.
(b)Using the NPV method, projects with the highest NPV is ranked highest.
(c)Using the IRR method, the investment with the highest IRR is ranked highest.
A particular method would seem superior to the other two depending on the terms. For instance, in terms of time-consumed for computation, the payback method is superior to the other two. On
