Since 64 = 2⁶ hence we will have total 7^th stages in the tournament with last 7th stage is the final match.

Total number of matches is 32 + 16 + 8 + 4 +2 + 1 = 63
Or else since total number of players is 64 hence number of matches must be 64 - 1 = 63

Seed 9 played with seed 56 in stage 1, with seed 24 in stage 2, But seed 11 can reach the final if he beats seeds 6, 3 and 2 in stage 3 4 and 5 respectively.

If all the matches in stage 1 is an upset except the last match where seed 32 won, then in stage 2 seed 32 is the highest seeded player who can win the tournament without causing an upset.

From the solution of previous question we have seen that seed 32 can win the tournament without causing an upset by him. So seed 15 can also win the tournament without causing an upset by him.

From the table F won 4 matches.

From the table G lost 4 matches.

From the table E won against C and G

C and E won 2 matches.
