The winnings will be equally split between all the players who tied up for that rank.
For example, if the winning amount for Rank 1 is Rs.1,000 and for Rank 2 is Rs.500, and if two players tie for the 1st rank, the winnings for both 1st and 2nd ranks will be split equally between both the winners. In this case, both the players will win Rs.750 each (Rs.1000 + Rs.500)/2 = Rs.750
