Answer: Mohandas Gandhi
It is not believable that Jamal would not know this answer, since an identical picture of Mohandas K. "Mahatma" Gandhi, the creator of "passive resistance" and the architect of Indian independence in 1948, appears on all Indian paper currency. Instead, the bills are differentiated by size, by color and by the picture on the reverse side. In fact, the current series of Indian currency, which has been in use since 1996, is generally known as the "Mahatma Gandhi series."
Although you need to answer 15 questions correctly to win on "Kaun Banega Crorepati", the same number needed to win on both the U.S. and U.K. versions of "Millionaire", Jamal was only shown answering nine questions in the movie -- the nine questions that make up the rest of this quiz. Viewers have no idea what happened to the other six questions, which are not discussed, but it hardly seems possible that someone who didn't know Gandhi's picture was on all Indian paper currency could have answered any other questions without suspicion, let alone six of them.
