If I do not know the answer of a particular question, I will ask for a clarified question to understand the context of that particular question. Even after that, if I find that I cannot find the answer yet, then I will say that I do not have the answer right now, but I will get back to you as soon as I have the answer. And after that, I will get back to someone who can give me a good idea about the answer, and I will quickly get back to the person and provide him or her the answer.
