ANSWER:

You must pray 3 more rakahs after getting up because when praying behind a resident imam, you must follow him and pray in full. 

I am a Musafir in a town. Participated Dhuhr fardh jamat in the last rakat. After Imam finishes salat, how many rakat I have to finish, will it be one more or three more rakat?
