Read the following passage carefully and answer the questions which follow.
In an Australian open tournament, the top 32 players of the world participate. These are seeded as 1 to 32 based on their likelihood of winning the tournament with seed 1 being the most likely person to win the tournament.
An upset is said to have occurred when a low seeded player defeats a player who is seeded higher than him. For example, a player seeded 12 beating a player seeded 9 is an upset.
In the first match, seed 1 is scheduled to play against seed 32,
In the second match seed 2 is scheduled to play against seed 31 and so on till seed 16 playing seed 17 in 16th match. The teams losing their matches are knocked out of the tournament while winners advance to the next round. There are no ties in the tournament.
In the second round, the winner of match no. 1 plays against the winner of match no. 16, winner of match no. 2 plays against the winner of match no. 15 and so on.
The same process is repeated in each of the subsequent rounds till the last round.
