CAT 2021 Slot 2: Variable Reasoning (VARC) Analysis
Preparation Tips, Question Breakdown, and Common Pitfalls
The CAT 2021 exam introduced significant changes to the VARC (Variable Reasoning and Critical Analysis) section, emphasizing data interpretation, logical reasoning, and analytical skills. Slot 2 of the exam typically follows a pattern of 10 VARC questions. Below is a structured analysis of the section, focusing on key themes, question patterns, and strategies to tackle VARC effectively.
1. Key Themes in Slot 2 VARC (2021)
Data Interpretation (DI):
Graphs/Charts: Time-series data, comparative analysis, and percentage-based questions.
Caselets: Complex scenarios with multiple variables (e.g., sales, production, costs).
Logical Reasoning:
Matrix Completion: Missing values in a grid based on row/column rules.
Pictorial Reasoning: Analyzing patterns in figures (e.g., arrows, shapes).
Critical Analysis:
Passage-Based Questions: Summarizing arguments, identifying assumptions, and evaluating conclusions.
2. Question Analysis & Strategies
A. Data Interpretation (DI)
Example Question (Caselet):
"A company’s sales data for 5 years (2016–2020) is given in a table. Calculate the year-on-year growth rate and identify the year with the highest % increase in revenue."
Strategy:
Skim the table for headers (years, revenue, costs).
Use formulas for growth rate: (Current Year Revenue – Previous Year Revenue) / Previous Year Revenue × 100.
Compare % values to find the maximum.
Common Error: Misidentifying "revenue" vs. "profit" in calculations.
B. Matrix Completion
Example Question:
A 3x3 matrix has numbers in rows (1–3) and columns (A–C). Fill the missing value in cell (3, B) based on the pattern.
Strategy:
Check row-wise arithmetic (e.g., sum/difference of numbers).
Look for column-wise multiplicative patterns (e.g., ×2, –1).
Verify consistency across the matrix.
Common Error: Overcomplicating patterns (simpler arithmetic often suffices).
C. Critical Analysis
Example Question (Passage):
A passage argues that "increased automation reduces manufacturing jobs but boosts productivity." Evaluate the validity of this claim.
Strategy:
Paraphrase the argument in your own words.
Identify premises (e.g., "automation replaces manual labor") and the conclusion.
Check for logical gaps (e.g., ignoring long-term economic impacts).
Common Error: Missing key premises or misinterpreting the author’s stance.
3. Time Management & Preparation Tips
DI & Matrix Completion:
Allocate 4–5 minutes per question; avoid getting stuck on one problem.
Practice calculating growth rates, averages, and percentages quickly.
Critical Analysis:
Spend 3–4 minutes per passage; summarize arguments in 1–2 sentences.
Focus on evaluating assumptions, not just summarizing.
Common Pitfalls to Avoid:
Overthinking: Trust your first instinct for simple patterns.
Calculation Errors: Double-check arithmetic, especially with decimals/percentages.
Misreading Instructions: Note if the question asks for "minimum" or "maximum" values.
4. Sample Practice Set
DI Question:
Given a bar graph of smartphone sales (2018–2022), find the ratio of Q4 to Q1 sales in 2021.
Answer: Use the bar heights for Q4 and Q1 2021; simplify the ratio.
Matrix Question:
Complete the matrix with values adhering to row/column rules:
| Row 1 | Row 2 | Row 3 |
|-------|-------|-------|
| 5 | 12 | ? |
| 8 | 16 | 24 |
| 3 | 6 | 9 |
Answer: Row 3 follows Row 1 × 3 = Row 3, so 5 × 3 = 15.
Critical Analysis Question:
Does the author’s claim that "AI will make education more accessible" hold true? Justify.
Answer: Highlight premises (e.g., online courses) and counterarguments (e.g., digital divide).
5. Final Tips for CAT 2021 VARC
Practice past papers (2019–2021) to熟悉 question patterns.
Use official mocks (like TCS, IIM CAT) for timed practice.
Focus on accuracy over speed; avoid guesswork in DI.
Review answers to identify recurring mistakes (e.g., percentage vs. percentage points).
By mastering these strategies and practicing consistently, candidates can improve their VARC scores significantly. For more sample questions and detailed solutions, refer to CAT 2021 answer key and prep books like Crack CAT 2021 by Arun Shukla.
Good luck with your CAT preparation! 🚀
