Sushil Kumar, a computer operator and tutor from the eastern state of Bihar, took the $1million jackpot home, after being declared a millionaire on Kaun Banega Croreparti.
The lucky participant’s brother told reporters that his win was down to listening to the BBC’s Hindi service on a regular basis.
Mr Kumar’s win has been compared to the plot in the 2009 Oscar hit, Slumdog Millionaire, which saw a young man from the slums win the coveted prize.
The 27 year old told reporters of his surprise.
“I never thought in my wildest dreams that I could do this” he said.
The newly wed, who married five months ago, earns a monthly salary of less than $150 (£93.75) and told the BBC that he plans to use the money to pay off his debts and buy a new house for his family.
