Solution and Explanation:
The following is used in order to calculate the internal rate of return
year  Cash flow  Â
0 -$152000 Â Â
1 $71800 Â Â
2 $86900 Â Â
3 -$11200 Â Â
Internal rate of return -2.07 percent ( the internal rate of return has been calculated by using the excel sheet) Â
The IRR rule cannot be applied in this case. Since, the cash flow direction changes twice, there are two internal rate of return. Thus, the Internal rate of return cannot be used to determine acceptance or the rejection.
