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.

Prof. Singh has been tracking the number of visitors to his homepage? His service provider has provided him with the following data on the country of origin of the visitors and the university they belong to.

Question 1

To which country does University 5 belong?

India or Netherlands but not USA

India or USA but not Netherlands

Netherlands or USA but not India

India or USA but not UK

Solution

On day 3,

2 people were from university 4 and 1 person was from university 6.

2 people were from Uk and 1 person was from USA.

Hence University 4 = UK

and University 6 = USA

On day 2,

1 person was from university 3 and 2 people were from university 8.

1 person was from the Netherlands and 2 people were from India.

Hence, Univerisity 3 = Netherlands

University 8 = India

On day 1,

1 person was from University 1

1 person was from University 5

2 persons were from university 2

2 people were from university 7.

1 person was from India

1 person was from the Netherlands

2 persons were from Canada

2 persons were from the UK.

Hence University 1 can be from India/ Netherlands

University 5 can be from Netherlands/ India

University 2 can be from UK/ Canada

University 7 can be from Canada/ UK.

According to given conditions there are following possibilities of university belonging from specific country .

We can clearly make out that University 5 belongs to India or Netherlands but not USA. Hence option A.

Instructions

Directions for the following four questions: Answer the questions on the basis of the information given below.

Question 4

Visitors from how many universities from UK visited Prof. Singh's homepage in the three days?

Solution

On day 3, there were 2 visitors from UK and 1 from USA. On the same day, the site was visited by 2 persons from University 4 and 1 from University 6. So University 4 is located in UK and University 6 is in USA. Similar reasoning for day 2 gives us the conclusion that University 3 is located in Netherlands and University 8 is in India. On day 1, the number of visitors from USA is 1 and that from University 6 is 1. University 6 is in USA (derived above), which implies no other university is in USA. The number of visitors from India on day 1 is 1. Also, no visitor from University 8, which is in India has visited the site on day 1. This implies that one of University 1 and University 5 is in India and the other in Netherlands. A similar logic gives us that one of University 2 and University 6 is in UK and the other in Canada.

We can see that university 4 and university 7 from UK visited prof. Singh's homepage in the three days.

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
