Answering a Question with a Question

One day Akbar asked Birbal, "Birbal, can you tell me how many bangles are on your wife's hand?"  Birbal said, "No, Huzoor, I cannot."  "You cannot? Although everyday you see her hand, still you cannot tell how many bangles are on her hand. How is that?" said Akbar.

Birbal said, "Let's go to the garden, Your Majesty. And I will tell you "How is that" and they both went to the garden. They both went down a small staircase which led to the garden. After reaching in the garden Birbal asked, "You daily climb up and down this small staircase, could you tell how many steps it has?"

Akbar smiled and then changed the subject.
