A loan processing office receives 4 loan applications every hour. The office has 2 departments. The first department takes on average 20 minutes to do a preliminary verification of the applications and 20% are rejected directly without going through the second department. The remaining 80% goes to the second department and takes 60 minutes per request and then an acceptance or rejection letter is sent to the client. On average, how many applications are there in the first department (including those waiting)? How many are there in the second (including those who are waiting)?
