What are DI connected data sets in CAT?

These are Data Interpretation sets where multiple tables, charts, or conditions are interlinked, requiring you to analyze relationships across datasets.

Are connected data sets important for CAT 2026?

Yes, such sets are commonly seen in LRDI and test your ability to handle complex and layered information under time pressure.

What is the best strategy to solve these DI sets?

Start by understanding all given data, identify connections between datasets, and structure the information before solving questions.

How can I improve in DI with connected data?

Practice diverse sets, focus on data structuring, and improve calculation speed using approximations and shortcuts.

Which resources are best for DI preparation?

Platforms like Cracku offer high-quality DI sets, previous year questions, and detailed explanations aligned with CAT preparation.

What mistakes should I avoid in these questions?

Avoid jumping into calculations without understanding the data. Misinterpreting relationships between datasets is a common error.

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 games. 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 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 while the M-index is the middle number, if his scores are arranged in a non-increasing order.

Question 5

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

More than 2

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

Only Kaif, Rahul or Yuvraj
