Indian citizens generally do require a visa in Germany, even for a short transit in an international airport. However, the Romanian visa exempts you from the airport transit visa requirement if you can transit without leaving the transit area of the airport (which is almost certainly your case).
Many web pages only mention valid US visas in this context but the rules are exactly the same for Romanian visas. The answer to the following earlier questions therefore also apply: Do I need a transit visa in Frankfurt, Germany on the way to India? and Do I require airport transit visa at Frankfurt?
