Employers want to see how candidates think. For tough or oddball interview questions, it's not always about getting the right answers it's about how you tackle a challenging problem. The question for employers may be really about how fast you think on your feet.
When faced with tough questions like these, take a deep breath, slow down and then sound out your thinking process aloud and walk the interviewer through how you get to an answer.
If you feel the question is unrelated to the job or company, before trying to respond, very politely ask the interviewer, "In order to best get to what you are looking for from me, can you provide more detail as to how the problem relates to how problems are solved here?" You have to ask this delicately though as you don't want the interviewer to think you are being defensive or want to duck the question.
