I have an existing app (without ads) published on Google Play Store. Now, I'm working on a new version with more features (and incorporating ads). So while adding the app to Admob, should I link the existing previous version app in Playstore or should I give 'App not published' ?

You should link the existing version of the app. I understand your confusion is because there are no ads in the existing app. But since it is published, there is nothing wrong in linking Admob to it as eventually you are going to submit the new version to the same app on Playstore.
