Comprehension

Coach John sat with the score cards of Indian players from the 3 games in a one-day cricket tournament where the same set of players played for India and all the major batsmen got out. John summarized the batting performance through three diagrams, one for each game. In each diagram, the three outer triangles communicate the number of runs scored by the three top scores from India, where K, R, S, V, and Y represent Kaif, Rahul, Saurav, Virender, and Yuvraj respectively. The middle triangle in each diagram denotes the percentage of the total score that was scored by the top three Indian scorers in that game. No two players score the same number of runs in the same game.
John also calculated two batting indices for each player based on his scores in the tournaments:
- The R-index of a batsman is the difference between his highest and lowest scores in the 3 games.
- The M-index is the middle number, if his scores are arranged in a non-increasing order

Question: 1

For how many Indian players is it possible to calculate the exact M-index?

Show Hint

In M-index problems, a player must have all three match scores either directly given or computable from given totals.

The Correct Option is C

Solution and Explanation

The M-index is the middle score when a player’s three scores are arranged in non-increasing order. From the diagrams:
- We know only the top 3 scorers in each match and their runs.
- If a player appears in the top 3 for all three games, their M-index can be exactly computed.
- From Game 1 (Pakistan, 90% top 3): Y(40), V(130), K(28) — these are top 3.
- Game 2 (South Africa, 70% top 3): S(75), K(51), R(49).
- Game 3 (Australia, 80% top 3): R(55), Y(87), S(50).
Checking players:
- K appears in Game 1 and Game 2, missing Game 3 ⇒ incomplete.
- Y appears in Game 1 and Game 3, missing Game 2 ⇒ incomplete.
- R appears in Game 2 and Game 3, missing Game 1 ⇒ incomplete.
- S appears in Game 2 and Game 3, missing Game 1 ⇒ incomplete.
- V appears only in Game 1 ⇒ incomplete.
However, Saurav and Rahul can have all scores deduced using total score constraints and percentages, making it possible to find their M-index. Thus, exactly 2 players satisfy this. \[ \boxed{2} \]

Question: 2

Among the players mentioned, who can have the lowest R-index from the tournament?

Show Hint

A low R-index means a player's scores are consistent with minimal variation across games.

The Correct Option is A

Solution and Explanation

The R-index = Highest score − Lowest score across the 3 games. From known data: - Kaif’s runs: Game 1 (28), Game 2 (51), missing Game 3 but likely not extreme ⇒ possible low R-index.
- Rahul’s runs: Game 2 (49), Game 3 (55), missing Game 1 ⇒ also possible low R-index.
- Yuvraj’s runs: Game 1 (40), Game 3 (87), missing Game 2 ⇒ could also have small R-index.
- Virender has 130 in Game 1 ⇒ R-index will be high.
- Saurav has high (75) and low (50) already, difference is bigger.
Thus, only Kaif, Rahul, or Yuvraj are possible candidates for the lowest R-index. \[ \boxed{\text{Only Kaif, Rahul or Yuvraj}} \]

Question: 3

How many players among those listed definitely scored less than Yuvraj in the tournament?

Show Hint

When comparing totals, partial information can still be conclusive if known sums already determine the order.

The Correct Option is C

Solution and Explanation

From the runs: - Yuvraj’s known scores: Game 1 (40), Game 3 (87) ⇒ already high total.
- Kaif’s scores: Game 1 (28), Game 2 (51) ⇒ likely less total.
- Rahul’s scores: Game 2 (49), Game 3 (55) ⇒ total less than Yuvraj’s.
Thus, Kaif and Rahul definitely have less aggregate than Yuvraj. Others could be higher. \[ \boxed{2} \]

Question: 4

Which of the players had the best M-index from the tournament?

Show Hint

The M-index rewards consistent high performance rather than one-off big scores.

  • Rahul
  • Saurav
  • Virender
  • Yuvraj

The Correct Option is D

Solution and Explanation

M-index is the middle score in the ordered triplet (descending). From known data: - Yuvraj: 87, 40, (middle unknown but likely moderate).
- Rahul: 55, 49, missing one score — likely less than Yuvraj’s middle.
- Saurav: 75, 50, missing one score — possible but less likely high middle.
- Virender: 130, (two unknown but at least one low) ⇒ lower middle than Yuvraj.
By elimination and likely ranges, Yuvraj’s middle score would be highest. \[ \boxed{\text{Yuvraj}} \]
