Show answer & explanation
Correct answer: B
Solution: 2
Clearly, in 5th (last) round two teams participated out of which 1 team wins the game as given after every round half the teams were eliminated.
Then for 4th round 2 ´ 2 = 4 teams had qualified.
3rd round = 4´ 2 =8 teams had qualified
2nd round = 8 ´ 2 = 16 teams had qualified
Hence in 1st round = 16 ´ 2 = 32 teams have participated.
So 32 teams participated in the race.
