Here's what I would do. On the first couple, I would politely state that I wasn't positive on my answer, but I think it's...., but I'm not 100 percent. On the third question, I would say "oh, I get this, very interesting, you would like to know how I would answer a question from a client or a potentional client when I might not know the answer, well, here's how I handle situations like that..." Then you get to impress them with your sales skills.

Good luck,
