Title: DILR CAT 2020 Slot 1: Detailed Solutions & Strategic Approach
Content: English
The Data Interpretation and Logical Reasoning (DILR) section in CAT 2020 Slot 1 tested aspirants on analytical skills and logical structuring. Below is a breakdown of key topics, sample questions, and solutions to help decode the paper effectively.
1. Key Topics Tested in DILR (Slot 1)
Data Interpretation (DI):
2 Sets (each with 4 questions)
formats: Bar Graphs, Caselet Analysis, and Mixed Graphs.
Logical Reasoning (LR):
Blood Relations
Seating Arrangements (Linear & Circular)
Coding-Decoding
Circular Arrangement with Constraints
2. Sample DI Question & Solution
Question 1 (Caselet Analysis):
“A company has 6 departments (A-F). Each department has 4 employees. The following table shows the number of employees promoted from each department in 2019 and 2020. Answer the questions based on the data.”
Department
2019 Promotions
2020 Promotions
A
2
3
B
1
2
C
3
1
D
4
4
E
2
3
F
1
2
Question: What is the percentage increase in promotions in Department C from 2019 to 2020?
Solution:
2019 Promotions in C = 3
2020 Promotions in C = 1
Increase = 1 - 3 = -2 (decrease)
Percentage Change = (-2/3) × 100 ≈ -66.67%
3. LR Question: Blood Relations
Question:
“Pointing to a girl, Ravi said, 'She is the daughter of my father's brother.' How is the girl related to Ravi?
Solution:
Ravi's father's brother = Ravi's uncle.
Uncle’s daughter = Ravi’s cousin.
Answer: The girl is Ravi’s cousin.
4. Tips for DILR Success
DI Strategy:
Skim graphs/charts first; note units, axes, and trends.
For caselets, create flowcharts or tables to map relationships.
LR Shortcuts:
Blood Relations: Use family tree diagrams for complex scenarios.
Circular Arrangements: Fix one person’s position to avoid repetition.
Time Management: Allocate 30 mins to DI and 30 mins to LR.
5. Common Pitfalls to Avoid
DI: Misreading axes labels or ignoring footnotes.
LR: Overlooking constraints (e.g., "no two people sit together").
General: Neglecting to verify answers in time-sensitive questions.
6. Final Takeaways
Practice past papers to identify recurring patterns (e.g., 2020’s focus on caselets).
Use official CAT mock tests to simulate exam conditions.
Revise formulas for percentages, ratios, and algebraic equations.
Conclusion: Mastering DILR requires a blend of speed, accuracy, and strategic time allocation. Focus on clarity in interpreting data and eliminating logical contradictions.
Note: For exact question papers, refer to CAT 2020 official resources or trusted prep platforms like Toppers CAT.
