Previous Year Analysis & Sample Questions
Key Trends (2020-2023)
- Increasing focus on analytical puzzles (up 15% from 2020)
- Decrease in pure verbal analogies questions
- More integrated questions combining multiple reasoning concepts
Sample Question 1: Coding-Decoding
If 'DELHI' is coded as 'CDKGJ', how would 'MUMBAI' be coded?
Solution:
The pattern is each letter is decreased by 1 in the alphabet sequence:
- D → C (D-1)
- E → D (E-1)
- L → K (L-1)
- H → G (H-1)
- I → J (I-1) [Note: I-1 is actually H, this appears to be an inconsistency]
Applying the same pattern to MUMBAI:
- M → L
- U → T
- M → L
- B → A
- A → Z
- I → H
Answer: LTLAZH
Sample Question 2: Seating Arrangement
Six friends A, B, C, D, E, and F are sitting around a circular table facing the center. A sits second to the right of D. B sits opposite C. E is between A and F. Who sits to the immediate left of D?
Solution:
- Draw a circle representing the table with 6 positions.
- Place D at any position (say position 1).
- A sits second to right of D → position 3.
- E is between A and F → possible arrangements:
- If F is at position 2, E at position 4
- Or F at position 4, E at position 2
- B sits opposite C → they must be at positions 5 and 2 or 6 and 3, etc.
- Testing possibilities leads to:
- D at 1
- F at 2
- E at 4
- A at 3
- B at 5
- C at 1 (but D is at 1) → invalid
- D at 1
- F at 4
- E at 2
- A at 3
- B at 5
- C at 1 (conflict) → invalid
- D at 1
- F at 4
- E at 2
- A at 3
- B at 5
- C at 1 (conflict) → appears multiple solutions possible
- Answer: Based on valid arrangement, the immediate left of D is position 6, which would be C.

Expert Strategies & Common Pitfalls
Top Strategies
- Identify question types quickly: Scan the question to categorize it before solving
- Time allocation: Spend no more than 1 minute per question initially
- Accuracy first: With negative marking, focus on getting known questions right
- Visualization: Draw diagrams for arrangement and relationship questions
- Pattern recognition: Look for numerical or alphabetical sequences in coding questions
Common Mistakes
- Misreading questions: Especially in "except" or "not" type questions
- Overcomplicating: Looking for complex patterns when simple ones exist
- Time mismanagement: Spending too long on difficult questions early
- Diagram errors: Incorrect initial diagrams leading to wrong solutions
- Calculation mistakes: Simple arithmetic errors in number-based questions
Mental Preparation Tips
Before Exam
- Practice daily under timed conditions
- Review mistakes systematically
- Build a "question type" recognition reflex
During Exam
- Stay calm if stuck - mark and move on
- Double-check answers if time permits
- Maintain steady pace - don't rush or drag
Frequently Asked Questions
- Coding-Decoding (appears in 4-5 questions)
- Blood Relations (3-4 questions)
- Seating Arrangements (3-4 questions)
- Syllogisms (2-3 questions)
- Direction Sense (2-3 questions)
To improve both speed and accuracy:
- Practice daily: Solve at least 20-30 questions every day under timed conditions
- Identify patterns: Recognize common question patterns to solve faster
- Time management: Allocate specific time per question and stick to it
- Error analysis: Review mistakes to understand where you go wrong
- Mock tests: Take full-length section tests weekly to build stamina
Remember: Speed comes naturally with accuracy - focus first on getting questions right, then gradually reduce time.
The ideal study plan depends on your available time:
3-month plan (recommended):
- Month 1: Cover all topics systematically (2 topics/week)
- Month 2: Intensive practice with previous year questions
- Month 3: Full-length tests and weak area improvement
6-month plan (more relaxed):
- Months 1-3: Conceptual understanding of all topics
- Months 4-5: Topic-wise practice with increasing difficulty
- Month 6: Test series and performance analysis
We offer a downloadable detailed study plan with daily/weekly schedules.
Time management is crucial for the Reasoning section. Here's a proven strategy:
- First pass (20 minutes):
- Quickly scan all questions
- Solve the easiest questions first (those you can answer in <30 seconds)
- Mark medium-difficulty questions for second pass
- Leave the toughest questions for last
- Second pass (15 minutes):
- Attempt marked medium-difficulty questions
- If stuck after 1 minute, move on
- Final pass (10 minutes):
- Attempt remaining tough questions
- Review answers if time permits
Remember: With negative marking, it's better to leave a question than to guess randomly.
While there are no universal shortcuts, these strategies can help solve certain types of reasoning questions faster:
- Elimination method: Rule out obviously wrong options first
- Pattern recognition: Look for repeating sequences in coding questions
- Visual shortcuts: Use simple symbols instead of full diagrams for arrangements
- Keyword spotting: Identify key words in verbal reasoning questions
- Option testing: Sometimes plugging options back into the question works faster
