This question is also from oliverlehmanns 75 questions. This is regarding 32nd question, when I calculated the duration is coming as 39 days where as the answer shows 37 days.
I have taken FF-2 days as lead of 2 days and FS+3days as lag of 3 days. So I calculated the durations as 20(activity1)+10(activity2)+5-2(activity 3 has two days lead) + 6+3(as the activity 4 has 3 days lag) which comes to 39 days.
am I doing anythig wrong in calculation.
appreciate your help
Thanks in advance
