Connecting two power sources.

Hello, I have 2 power sources: one is 12V up to 48A and the other is 3.3V up to 21A. If I connect them in series I get 15.3V (lets call it "source 3"). How much current can I draw from "source 3" before I exceed the capabilities of one of my original sources? Thanks for your time.
