His 75 free sample questions (PMP® Exam Self-Assessment Test) is very popular. If you have not tried the test yet, please STOP reading this article.

He has given the answers and relevant references for all the 75 questions. He has not given any answer explanations, probably to encourage candidates to research themselves. I do encourage you to think and do a research before reading further on.

Answer Key for Oliver Lehmann PMP Exam Question No. 2

There are two projects in the question. We need to choose the project with a better returns based on the Net Present Value (NPV). The below table shows the given data.

Project #DurationCostReturns
19 months$250,000$120,000/ year
29 months$250,0001st year: $15,000
2nd year: $125,000
3rd year: $220,000

Since the cost and duration are the same for both projects, let us ignore those data; we will look into the returns/ benefits of the project only to compare.

Net Present Value (NPV) = FV/(1+r)t, where
FV = Future Value
r = rate of interest
t = time period

So, the NPV of project 1 considering first three years
= 120000 / 1.05 + 120000 / 1.052 + 120000 / 1.053
= $326790

NPV of project 2 considering first three years
= 15000 / 1.05 + 125000 / 1.052 + 220000 / 1.053
= $317709

Comparing the two values, project #1 is better. By, what percentage?
= (326790-317709) / 317709
= 0.029
= 2.90% (approximately 3%)

So, the first project is more attractive by approximately 3%.

Conclusion
