Question

In the 2020 summer Olympics' Javelin throw finals, Neeraj Chopra exhibited a spectacular performance to win the gold medal. The silver medal was won by Jakub Vadlejch and the bronze medal was won by Vitezlav Vesely. There were six rounds of throws with each athlete having one throw per round. The best of all the throws of each athlete is considered for the medal. Following were the observations about the throws:

  1. The first and second rounds were dominated by Neeraj Chopra with a gold medal performance in his second throw, while the other two athletes did not have any medal winning throws in these rounds.
  2. The throws in the last round by both Jakub Vadlejch and Vitezlav Vesely were fouls and were not considered for scoring.
  3. After four rounds, Vitezlav Vesely was in the second position and could not improve upon his best throw in the succeeding rounds.
  4. In the fourth round, the throw by Jakub Vadlejch was the best in that round.

In which round did Vitezlav Vesely have his best throw?

Solution

Eliminate Rounds 1, 2, 5, and 6 using observations (i)-(iii), then compare Round 3 and Round 4 using observations (iii) and (iv).

  1. By observation (iii), Vitezlav Vesely was in second position after Round 4 and did not improve upon his best throw in Rounds 5 or 6. Thus his best (bronze-medal) throw occurred in Rounds 1, 2, 3, or 4.
  2. By observation (i), neither Jakub Vadlejch nor Vitezlav Vesely had a medal-winning throw in Rounds 1 or 2. Hence Vesely's best throw occurred in either the Third or Fourth round.
  3. After Round 4, Vesely was in second position ahead of Vadlejch, meaning Vesely's best throw in Rounds 1-4 was better than Vadlejch's best throw in Rounds 1-4. However, by observation (iv), Vadlejch had the best throw in the fourth round (so Vesely's Round 4 throw was shorter than Vadlejch's Round 4 throw). Therefore, Vesely's best throw could not have been in Round 4; it must have been in the Third round.
Final answer

Option (A)

Common trap

Selecting Fourth without noticing that Vadlejch beat Vesely in Round 4 while Vesely was ahead of Vadlejch overall after Round 4.
