I can understand your frustration when you feel the question a client has asked in absurd, however I feel that the client would not be asking the question if they truly didn't know the answer.
As a certified train the trainer expert, I would recommend asking more questions of your client than talking. The objective would be for the client to discover the solution to the problem on their own based on the probing questions you are asking. The more a client can discover the solution on their own, the more likely they will remember the answer and not need your help in the future. You also come across as an expert by helping them find the solution.
