Um, when I don't know the answers to a question, really it depends on what the question is, but I usually tell the person that I don't currently know the answer, but I will definitely, you know, research the answer and see what I come up with, just so that I can make sure that I give them the proper knowledge, especially depending on what the question is. I never want my answer to affect someone else, so I definitely make sure that I get a better understanding by doing that research so that I am able to actually provide a useful and helpful answer for them.
