• STEP 1.) 1 Person who is both Doctor with Teacher will go. Now , we are left with 1 doctor and 3 lawyers.
  STEP 2.) 1 Person who is Doctor with Lawyer will go. Now, we are left with only 2 lawyers only.
  STEP 3.) These 2 lawyers left will go now since all go from 2 doctors, 3 lawyers and 1 teacher.
  
  So, Persons went on trip = 1(Doctor & Teacher) + 1(Doctor & lawyer) +2(Lawyers) = 4
