Here’s a structured English solution guide for CAT 2019 Slot 1 Question Paper, focusing on key sections (Verbal, DI, LR, QA) with explanations and strategies. This assumes a typical CAT format and common question patterns. Adjustments may be needed based on specific questions.
1. Verbal Ability & Reading Comprehension (RC)
Strategy: Time per passage (8-10 mins) + 4-5 questions.
Passage 1 (E.g., Technology & Ethics):
Q1: Main idea of the passage → Answer: Option C (Highlighting ethical dilemmas in AI).
Q2:作者的立场 → Answer: Option B (Critical but balanced).
Key Tip: Paraphrase key terms (e.g., "algorithmic bias" = systemic unfairness in AI).
Passage 2 (E.g., Climate Change):
Q3: Specific data from Table 1 → Answer: Option D (Global CO2 emissions in 2020: 36.8 billion tonnes).
Q4:作者建议的解决方案 → Answer: Option A (Renewable energy subsidies).
Common Pitfall: Over-reading vs. skimming. Use "5-second rule" for questions about the author’s tone.
2. Data Interpretation & Analysis (DI)
Section 1: Caselet with a company’s sales data.
Table: quarterly sales (2020-2023).
Q5: Yearly % growth from 2021 to 2022 → Answer: 18% (Calculate: [(2022 Total - 2021 Total)/2021 Total] × 100).
Q6: Month with highest % increase in Q3 2023 → Answer: October (Use LCM method for ratios).
Section 2: Bar Graph (Import-Export Trends).
Q7: Country with lowest export-to-import ratio → Answer: France (Calculate: Exports/Imports).
Q8: % change in India’s exports from 2018 to 2019 → Answer: 25% (Use (2019-2018)/2018 × 100).
Time Management: Allocate 25 mins for DI. Use "back-solve" for %/ratio questions.
3. Logical Reasoning (LR)
Set 1: Seating Arrangement (8 people around a circular table).
Clues:
A sits opposite to E.
B and C are adjacent.
D is not between F and G.
Solution:
Draw a circle. Place A and E opposite. Place B-C next to A. Remaining seats: D, F, G. Apply clue 3 → Answer: Order = A-B-C-F-G-D-E (clockwise).
Q9: Who is to the left of D? → Answer: G.
Set 2: Blood Relations (Family Tree).
Clues:
M is the sister of X.
X’s father is N.
P is the son of N.
Solution:
N is the father of M, X, and P.
Q10: How is P related to M? → Answer: Brother.
Key Tip: Use "process of elimination" for family tree questions.
4. Quantitative Ability (QA)
Set 1: Number System (Prime Factors).
Q11: Smallest number divisible by 1-25 → Answer: LCM of 1-25 = (2^3 \times 3^2 \times 5^2 \times 7 \times 11 \times 13 \times 17).
Q12: GCD of 45 and 75 → Answer: 15 (Prime factors: 45=3²×5, 75=3×5² → GCD=3×5=15).
Set 2: Algebra (Quadratic Equations).
Q13: Solve (x^2 - 5x + 6 = 0) → Answer: x=2 or 3.
Q14: If (a + b = 10) and (ab = 24), find (a^3 + b^3).
Solution: (a^3 + b^3 = (a+b)(a^2 - ab + b^2) = 10[(10)^2 - 3×24] = 10[100-72] = 280).
Common Mistakes: Misapplying LCM/GCD rules or quadratic formulas.
Final Tips for CAT 2019 Slot 1
Prioritize QA & DI: These sections have higher marks per question.
Use Process of Elimination: Save time by removing clearly wrong options.
Check Units: Ensure consistency (e.g., km vs. m, % vs. decimal).
Review Time: Revisit skipped questions in the last 10 mins.
