Problem:
The estimated values of the yearly ATCF (after tax cash flows) of a Project are given in the Table below. The duration of the Project is six years. The initial cost of the Project is $2,800,000. MARR (the minimum attractive rate of return) is 12%.

Determine:
- the value of X that would make      the IRR (internal rate of return) of the Project equal to 15% if Y = 3X
 
- the IRR (internal rate of      return) of the Project if X = 400,000 and Y= 1,000,000
 
- the value of X that would make      the ERR (external rate of return) of the Project equal to 15% if Y =      800,000
 
- the ERR (external rate of      return) of the Project if X = Y = 800,000
 
- the value of X that would make      the equivalent uniform annual value of the Project cash flow equal to      $980,000 if Y = 4X
 
Additional Information:
This question is basically belongs to Finance as well as it explains about computation of internal rate of return, external rate of return and annual value of cash flow for a project.
