The road adjacency value of a house is the number of its sides adjacent to a road. For example, the road adjacency values of C2, F2, and B1 are 2, 1, and 0, respectively. The neighbour count of a house is the number of sides of that house adjacent to occupied houses in the same block. For example, E1 and C1 can have the maximum possible neighbour counts of 3 and 2, respectively.The base price of a vacant house is Rs. 10 lakhs if the house does not have a parking space, and Rs. 12 lakhs if it does. The quoted price (in lakhs of Rs.) of a vacant house is calculated as (base price) + 5 × (road adjacency value) + 3 × (neighbour count).
The following information is also known.
1. The maximum quoted price of a house in Block XX is Rs. 24 lakhs. The minimum quoted price of a house in block YY is Rs. 15 lakhs, and one such house is in Column-E.
2. Row-1 has two occupied houses, one in each block.
3. Both houses in Column-E are vacant. Each of Column-D and Column-F has at least one occupied house.

A visa processing office (VPO) accepts visa applications in four categories - US, UK, Schengen, and Others. The applications are scheduled for processing in twenty 15-minute slots starting at 9:00 am and ending at 2:00 pm. Ten applications are scheduled in each slot.
There are ten counters in the office, four dedicated to US applications, and two each for UK applications, Schengen applications and Others applications. Applicants are called in for processing sequentially on a first-come-first-served basis whenever a counter gets freed for their category. The processing time for an application is the same within each category. But it may vary across the categories. Each US and UK application requires 10 minutes of processing time. Depending on the number of applications in a category and time required to process an application for that category, it is possible that an applicant for a slot may be processed later.

CAT 2023 Slot 1 DILR Exam Pattern and Marking Scheme
The Data Interpretation and Logical Reasoning section in CAT 2023 Slot 1 had a fixed structure that you should know before you attempt the paper. It carried 20 questions for 60 marks, with a strict 40-minute sectional time limit and no option to move back to other sections.
- Total questions: 20 in the Data Interpretation & Logical Reasoning section
- Section duration: 40 minutes (sectional time limit)
- Total marks: 60 (3 marks per question)
- Marking (MCQ): +3 for a correct answer, -1 for a wrong one
- Marking (TITA): +3 for a correct answer, no negative marking
- Question types: A mix of MCQ (multiple-choice) and TITA (Type In The Answer, non-MCQ) questions spread across 4 sets of 5 questions each, blending Data Interpretation (tables, distributions) with Logical Reasoning (arrangements, games and tournaments).
CAT 2023 Slot 1 DILR Set-wise Weightage and Difficulty
All 20 marks-worth of questions came from 4 sets of 5 questions each, so every set you cracked was worth up to 15 marks. Two sets were comparatively friendlier (easy to medium) while two were calculation-heavy (medium to difficult), which is why most students completed at most 2 full sets in the 40 minutes.
- Set 1 - Restaurants and Gigs: A Data Interpretation set on musicians and gigs that looked approachable but used statistical ideas like averages and medians, pushing it to moderate-to-difficult; 5 questions.
- Set 2 - Visa Processing: A Logical Reasoning set with counters serving multiple countries at different processing times and a heavy load of information to track, making it one of the tougher, time-consuming sets; 5 questions.
- Set 3 - Plots and Houses: An arrangement-based set of 5 questions, rated medium; one question in this set was widely flagged as having an inconsistency, so accuracy and verification mattered here.
- Set 4 - Distribution / Games Set: The most doable easy-to-medium set of 5 questions, best attempted first to bank quick, safe marks.

How to Use the CAT 2023 Slot 1 DILR Question Paper
Treat this paper as a timed selection drill, not just a solving exercise. The 40-minute limit means choosing the right 2 sets is half the battle, so practise scanning all 4 sets before committing.
- Spend the first 3 to 4 minutes reading all 4 sets and ranking them, then start with the easy-to-medium set (Set 4 here) to secure quick marks.
- Cap each chosen set at roughly 12 to 15 minutes; if you are stuck mid-set, abandon it rather than sinking your whole 40 minutes.
- On MCQ questions remember the -1 penalty and avoid blind guesses, but attempt TITA questions freely since they carry no negative marking.
- Cross-check the flagged Plots and Houses question against the solution so you learn to spot inconsistent data sets under pressure.
Good Attempts and Percentile Benchmark for DILR Slot 1
- An attempt of 9 to 12 questions with about 75 to 80 percent accuracy was considered a strong DILR performance in this slot.
- Clearing 9 to 12 questions accurately was enough to reach roughly the 99 percentile in DILR for Slot 1.
- Completing 2 full sets cleanly (10 questions) was a realistic target for most test-takers within the 40-minute window.
- A raw score in the low-to-mid 30s out of 60 in DILR was a healthy 99 percentile-range outcome given the moderate-to-tough level.
