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:
i.
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.
ii.
The throws in the last round by both Jakub Vadlejch and Vitezlav Vesely
were fouls and were not considered for scoring.
iii.
After four rounds, Vitezlav Vesely was in the second position and could
not improve upon his best throw in the succeeding rounds.
iv.
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?

• A. Third
• B. Fourth
• C. Fifth
• D. Sixth

Hint:

Eliminate rounds 1, 2 (Neeraj's story), 6 (fouls), and 5 (no improvement after round 4) first; then show round 4 is impossible because it would force Jakub's best to exceed Vitezlav's, contradicting Vitezlav being ranked ahead of Jakub after 4 rounds - leaving round 3.

Answer 1

The Correct Option is A

This is a constraint-elimination puzzle - treat each clue as a filter that removes rounds from the list of candidates for "Vitezlav's personal best round," then use one final logical contradiction to pick between what's left.

Candidates before applying clues: Rounds 1 through 6.

Filter 1 (clue i): Rounds 1 and 2 belonged to Neeraj's story - he set his gold-medal throw in round 2, and the passage explicitly says neither Jakub nor Vitezlav had a medal-defining throw in rounds 1-2. Cross these off: candidates left = {3, 4, 5, 6}.

Filter 2 (clue ii): Round 6 was a foul for both Jakub and Vitezlav, so it can't count as anyone's best. Cross off round 6: candidates left = {3, 4, 5}.

Filter 3 (clue iii): Vitezlav didn't improve his best after round 4 - meaning rounds 5 and 6 didn't produce a new personal best for him. Cross off round 5: candidates left = {3, 4}.

Final tie-break (clue iv + logic): Now ask: could Vitezlav's personal best have been set exactly in round 4? Clue (iii) also tells us that after 4 rounds, Vitezlav is ranked above Jakub - meaning Vitezlav's best-so-far throw is longer than Jakub's best-so-far throw. But clue (iv) says round 4's single best throw among the three athletes belonged to Jakub. If Vitezlav's personal best were the round-4 throw, then Jakub's round-4 throw (being round 4's best) would have to beat it - which would make Jakub's best-so-far bigger than Vitezlav's, directly contradicting the ranking in clue (iii). So round 4 cannot be the answer.

That leaves only one candidate standing: round 3.

\(\text{Vitezlav's personal best throw} = \text{Round 3}\)

Correct option: (A) Third
