TOPIC: Duration question

Can someone help explain the correct answer ?

Activity 1 has a duration of 20 days, activity 2 of 10 days, activity 3 of 5 days and activity 4 of 6 days.

with the following path

MILSTONE A --FS-- -ACTIVITY 1 ---FS ---ACTIVITY 2 ----FF-2days

---

ACTIVITY 3---FS +3 days

---

ACTIVITY 4----FS----MILESTONE B

What is the minimum total duration between the milestones A and B?



36 days
37 days
39 days
42 days

Why is the answer 37 days?

Rosa,

I suspect you haven't received an answer yet because your question is a little difficult to comprehend. Can you display the schedule problem as a graphic? This would help us better visualize it and work out a solution for you. Thanks!

I have attached a PDF of the diagram to help with the question.

Thank you

In ref to 1st post, when activities have FF relationship we need to consider larger duration due to overlapping each other: Activity 1 (20 d)+ Activity 2 (10-2 =8 d+3 )+ Activity 4 (6 d) = 37 days.

In ref to the attached PDF, the correct answer is "B".
Thanks,

Sorry I attached the wrong diagram. The question came from Oliver Lehman's 75 free sample questions # 31. His answer is 37 days. I have attached the right diagram. Thank you for your explanation.

Rosa,

I don't see the attachment you referenced in your latest post.
