- it is said that among 2 players only one is selected as winner.
At the 8th round one player is declared as winner. Which means that there were 2 players playing at the 8th round.
In order to get 2 players ath the 8th round there must be 4 players at the 7th round so that 2 are selected to the 8th round.
Hence, there are
8 players at 6th round
16 players at 5th round
32 players at 4th round
64 players at 3rd round
128 players at 2nd round
256 players at 1st round
Hence the answer is 256 - 5 years agoHelpfull: Yes(0) No(0)
