Oliver lehmann (75Q) lead lag question

hello all

               Could someone please help me understand this question.

 

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

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

  36 days
  37 days
  39 days
  42 days

answer is b) 37 days.

Hello All 

                 I got the answer it was in another post called 'duration'. clearly explained by robleis. My concept of leads and lags is crystal clear now.
