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!

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,

Mahabub

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.
