Previous Year Analysis & Sample Questions
Trend Analysis (2021-2023)
| Year | Total Qs | Difficulty | Most Asked Topics | Cut-off (General) |
|---|---|---|---|---|
| 2023 | 50 | Moderate | Logical Reasoning (14), Puzzles (9) | 68/100 |
| 2022 | 50 | Moderate-Difficult | Puzzles (11), DI (8) | 62/100 |
| 2021 | 50 | Easy-Moderate | Verbal (13), Logical (12) | 72/100 |
Solved Sample Questions
Question 1: Logical Reasoning (2023 Pattern)
Statement: All engineers are logical thinkers. Some logical thinkers are good at puzzles. Rahul is an engineer.
Conclusion: Rahul is good at puzzles.
Solution:
The conclusion doesn't necessarily follow from the statements. While all engineers are logical thinkers, and some logical thinkers are good at puzzles, this doesn't mean all engineers are good at puzzles. The word "some" indicates a partial overlap, not complete inclusion.
Correct Answer: Conclusion doesn't follow
Tip: For such questions, draw Venn diagrams to visualize relationships.
Question 2: Analytical Puzzle (2022 Pattern)
Five friends - A, B, C, D, E - are sitting in a row facing north. A sits to the immediate left of C and immediate right of B. E sits at the extreme right end. Who sits in the middle?
Solution:
Let's arrange the information step by step:
- E is at extreme right: _ _ _ _ E
- "A sits to the immediate left of C" means A is immediately before C: A C
- "A sits to the immediate right of B" means B is immediately before A: B A C
- Now we have: B A C _ E
- The only person left is D who must occupy the 4th position: B A C D E
The middle position (3rd) is occupied by C.
Correct Answer: C
Tip: Always fix definite positions first (like E here) and build around them.
Question 3: Data Interpretation (2023 Pattern)
The table below shows the number of books read by students in a college:
| Student | Books |
|---|---|
| A | 12 |
| B | 8 |
| C | 15 |
| D | 10 |
| E | 5 |
What is the average number of books read per student?
Solution:
To find the average:
- Sum of books = 12 + 8 + 15 + 10 + 5 = 50
- Number of students = 5
- Average = Total books / Number of students = 50 / 5 = 10
Correct Answer: 10
Tip: For averages, look for numbers that might add up to round figures to simplify calculations.

Expert Strategies & Common Pitfalls
Winning Strategies
- First Pass Strategy: Solve all easy questions first (1-1.5 mins/question), then medium (2 mins), leave tough ones for end
- Elimination Technique: For uncertain answers, eliminate clearly wrong options to improve guessing accuracy
- Puzzle Shortcuts: Learn quick diagramming methods for seating arrangements (tables, circles)
- Verbal Patterns: Memorize common coding patterns (A=1, B=2 or reverse alphabet positions)
- DI Approximations: Round numbers for faster calculations (e.g., 493 as 490)
Common Pitfalls
- Over-Investing Time: Spending too long on difficult questions and rushing through easier ones later
- Misreading Questions: Not paying attention to "except", "not true", or other critical words
- Calculation Errors: Simple math mistakes in DI questions despite correct approach
- Pattern Over-Assumption: Assuming series follow common patterns without verifying
- Ignoring Options: Not using answer choices to validate solutions, especially in puzzles
Mental Preparation Tips
Time Pressure
Practice with 10% less time than allotted to build speed buffer
Stress Management
Learn breathing techniques to stay calm during tough questions
Focus Techniques
Train with distractions to improve concentration during exam
Frequently Asked Questions
The Reasoning section typically carries around 100 marks out of the total exam (varies slightly by PSU). In most PSU exams, it accounts for 25-30% of the total marks in the written test stage. For example, in 2023:
- ONGC: 100 marks out of 400 (25%)
- BHEL: 100 marks out of 350 (~28.5%)
- NTPC: 100 marks out of 300 (33.3%)
Based on recent patterns, these topics carry maximum weightage:
- Logical Reasoning (12-15 questions): Statement-conclusions, arguments, logical deduction
- Analytical Puzzles (8-10 questions): Seating arrangements, blood relations, scheduling
- Verbal Reasoning (10-12 questions): Coding-decoding, series completion, classification
Focus on these high-yield areas first, then move to other topics like Data Interpretation and Non-Verbal Reasoning.
Improving speed and accuracy requires targeted practice:
- Timed Practice: Regularly solve questions with strict time limits (start with 2 mins/question, reduce to 1.5 mins)
- Error Analysis: Maintain a log of mistakes to identify recurring patterns
- Shortcut Techniques: Learn approximation methods for DI, quick diagramming for puzzles
- Sectional Tests: Take topic-wise tests to build speed in specific areas
- Full-Length Mocks: Simulate exam conditions weekly to build stamina
Most students see significant improvement after 6-8 weeks of consistent practice.
Yes, most PSU exams have negative marking in the Reasoning section. The typical pattern is:
- For wrong answers: 0.25 marks deducted per question
- For unanswered questions: No deduction
An effective study plan depends on your available time:
For 3-month preparation:
- Month 1: Concept building - cover all topics systematically
- Month 2: Intensive practice - focus on weak areas
- Month 3: Mock tests & speed building
For 6-month preparation:
- Months 1-2: Foundation building with basic concepts
- Months 3-4: Advanced techniques and pattern recognition
- Month 5: Full-length practice tests
- Month 6: Revision and speed enhancement
We offer a detailed PDF study plan tailored to different preparation durations.
Time management is crucial for maximizing your score. Follow this approach:
- First Pass (30 mins): Quickly scan and solve all easy questions (1 min or less each)
- Second Pass (40 mins): Attempt moderate difficulty questions (1.5-2 mins each)
- Third Pass (20 mins): Tackle difficult questions, make educated guesses
- Final Check (10 mins): Review answers, ensure no unanswered easy questions
While there are no "magic" shortcuts, these techniques can save time:
- Option Elimination: Even if you can't solve completely, eliminate clearly wrong options to improve guessing odds
- Pattern Recognition: Memorize common series patterns (prime numbers, squares, alternating operations)
- Visual Shortcuts: For puzzles, use symbols instead of full names (B for Bharat, R for Ramesh)
- Approximation: In DI, round numbers for faster calculations (e.g., 493 as 500)
- Reverse Solving: For some questions, plug in options to see which fits
Remember: These are complements to, not substitutes for, proper understanding. First master concepts, then develop shortcuts.
