Amitabh Bachchan doesn't know the answers to the questions asked on the Kaun Banega Crorepati show; they aren't told in advance. He only finds out if the answer is correct or wrong after he answers, and until then, he's given a bit of a scare and some fun to keep the show entertaining. Amitabh Bachchan is given the right to change these questions.
