While, the Police inspector was questioning Jamal's knowledge, he asked Jamal whose picture was on the indian 1000 Rupeee Note, and then showed him. When Jamal claimed not to know, whose picture was it?

This scene is from the movie 'Slumdog Millionaire' (2008). The 1000 rupee note (now discontinued) featured Mahatma Gandhi's portrait. Rajiv Gandhi appeared on the 500 rupee note, Indira Gandhi on notes after her death, and Jawaharlal Nehru has never appeared on Indian currency. The question refers to a pivotal scene in the film.
