I came through a mistake in the show . On the Wednesday show ,when a child Virat was playing, He was asked a question that 'From which state the tropic of cancer and the Indian meridian time passes ' Virat did not know the answer . So he use the lifeline of question changing . But before changing the answer, amitabh sir asked him to guess one for the audience ,Virat guessly answer Madhya Pradesh and according to the show that was correct. But the tropic of cancer and the standard meridian of India passes through Uttar Pradesh not Madhya Pradesh.... So KBC please rectify this mistake....
