Title: CAT 2022 Slot 2 QA (Question and Answer Guide)
Content: Indian Exam Solutions (English)
Here’s a structured guide to solving questions from CAT 2022 Slot 2, focusing on common question types, strategies, and solutions. This guide is tailored for Indian students preparing for the Common Admission Test (CAT), emphasizing logical reasoning, data interpretation, and quantitative aptitude.
1. Logical Reasoning & Data Interpretation (DI)
Key Question Types in Slot 2:
Caselets with Multiple Variables (e.g., Market Share Analysis)
Blood Relations/Seating Arrangements
Puzzles (Alphabets, Numbers, Cages)
Data Sufficiency (Data Interpretation Tables)
Example Question:
“A survey of 1000 employees in a company categorized their roles into three departments: HR (30%), Tech (50%), and Finance (20%). If 40% of HR employees are female, 60% of Tech employees are male, and 25% of Finance employees are female, how many male employees are there in total?”
Solution:
HR: 30% of 1000 = 300 employees.
Female HR: 40% of 300 = 120.
Male HR: 300 – 120 = 180.
Tech: 50% of 1000 = 500 employees.
Male Tech: 60% of 500 = 300.
Finance: 20% of 1000 = 200 employees.
Female Finance: 25% of 200 = 50.
Male Finance: 200 – 50 = 150.
Total Male Employees: 180 (HR) + 300 (Tech) + 150 (Finance) = 630.
Answer: 630 male employees.
2. Quantitative Ability (QA)
Common Topics in Slot 2:
Algebra (Quadratic Equations, Inequalities)
Geometry (Triangles, Circles, Coordinate Geometry)
Probability & Combinatorics
Number Systems (LCM, HCF, modular arithmetic)
Example Question:
“If ( x^2 - 5x + 6 = 0 ) and ( y^2 - 7y + 12 = 0 ), find the sum of all possible values of ( x + y ).”
Solution:
Solve ( x^2 - 5x + 6 = 0 ): Roots = ( x = 2, 3 ).
Solve ( y^2 - 7y + 12 = 0 ): Roots = ( y = 3, 4 ).
Possible sums: ( 2+3=5 ), ( 2+4=6 ), ( 3+3=6 ), ( 3+4=7 ).
Unique sums: 5, 6, 7.
Answer: 5 + 6 + 7 = 18.
3. Verbal Ability
Focus Areas in Slot 2:
Reading Comprehension (RC) – Focus on inference-based questions.
Para Jumbles – Sequence logical flow.
Sentence Rearrangement – Identify topic transitions.
Example RC Question:
“Based on the passage about renewable energy adoption in India, which sentence best supports the claim that solar power is the most promising source?”
Strategy:
Skim for keywords: “renewable energy,” “solar power,” “advantages.”
Look for data points (e.g., “solar accounts for 30% of new capacity”).
Answer: The sentence stating, “Solar power alone contributed 22% to India’s non-fossil fuel capacity addition in 2021.”
4. Time Management Tips for CAT Slot 2
DI/LR First: These questions are often solvable with fewer time constraints.
QA Last: Save algebra/geometry for later—these require deep focus.
Guess Smart: Eliminate obviously wrong options in Verbal.
5. Common Traps in CAT 2022 Slot 2
Data Interpretation: Misreading percentages (e.g., % of total vs. % of a subset).
Probability: Forgetting complementary events (e.g., P(A) ≠ 1 – P(B) if A and B are not mutually exclusive).
Algebra: Assuming linear relationships without checking quadratic roots.
Final Note: Practice past CAT papers rigorously, especially Slot 2 patterns. Focus on accuracy over speed—CAT rewards precision.
