I don't know an answer to questions. I will be nicely, I will say that I'm sorry. I don't know the answer to the question that you asked me and I don't want to mislead you. I definitely will call you right back or I will have my supervisor call you back and answer the question. The last thing I would want to do and mislead you to the wrong direction. That's how I usually answer to a question that I do not know.
