Need help in one of the question

A company has to make a choice between two projects, because the available resources in money and kind are not sufficient to run both at the same time. Each project would take 9 months and would cost $250,000.
    1.    The first project is a process optimization which would result in a cost reduction of $120,000 per year. This benefit would be achieved immediately after the end of the project.

    2.    The second project would be the development of a new product which could produce the following net profits after the end of the project:
1. year:     
$
15,000
2. year:
$
125,000
3. year:
$
220,000
Assumed is a discount rate of 5% per year. Looking at the present values of the benefits of these projects in the first 3 years, what is true?



Both projects are equally attractive.


The first project is more attractive by app. 7%.


The second project is more attractive by app. 5%.


The first project is more attractive by app. 3%.

Ans : D

1st project NPV = 120/1.05 + 120/(1.05*1.05) + 120/(1.05*1.05*1.05) = 327

2nd project NPV = 15/1.05 + 125/(1.05*1.05) + 220/(1.05*1.05*1.05) = 317

1st project's NPV is approx 3% more than 2nd project.

Correct answer is D.
