Ali is a Planning engineer considered the following three mutually exclusive investment projects (A, B, and C) at PTUK. He summarized the relevant data provided for these projects as; for project A, the initial investment is -200 , annual return is 22 and the salvage value is 200. For project B, the initial investment is -4000, salvage value is 2600 and the annual return is 620. For project C, the initial investment is -5450, annual retum is 740 and salvage value is 4300. The useful life for these projects is similar which is 5 years, and MARR=10% .
Which alternatives are feasible based on their ROR.
Consider the following two mutually exclusive projects being considered by an agency. The agency's MARR is 4% per
year and the projects have a service life of 5 years.
Answer the following questions.
Project 1
$14,600
$3,901
Present Worth (PW) $2,767
Initial cost
Annual revenues
b. Calculate the IRR of each alternative (use the trial-and-error method)
The IRR of Project 1 is% (Round to the nearest one decimal place)
The IRR of Project 2 is % (Round to the nearest one decimal place)
Project 2
$22,100
$5,638
$2,999
c. Perform the incremental IRR analysis to determine the project that is more economical:
Incremental IRR =% (Round to the nearest one decimal place);
