📘 Logical and Analytical Reasoning

🔹 What It Means

Logical Reasoning involves the process of thinking through information in a clear, organized, and structured way to reach a valid conclusion.
Analytical Reasoning deals with breaking complex problems into simpler parts, understanding relationships between components, and identifying patterns or sequences.
Together, they form the foundation of puzzle-based reasoning—a key section in many aptitude and competitive tests.

🧩 Puzzle-Based Problem Solving

🔹 What is it?

Puzzle-based problem solving refers to logic-based puzzles that test your ability to:

• - Interpret given conditions or clues
• - Connect the dots logically
• - Solve for unknowns using reasoning skills

These are often found in:

• - IQ tests
• - Banking and government exams (e.g., IBPS, SSC, UPSC)
• - Job selection tests
• - Entrance exams (e.g., CAT, GRE)

🧾 Detailed Types of Puzzles with Examples

1. Seating Arrangement Puzzles

- People are arranged in rows, circles, squares, etc.
- Types: Linear, Circular, Square, Facing inside/outside

Example:
- 8 people are sitting around a circular table. A is to the immediate left of B, and only 3 people sit between A and C. Who sits opposite D?
👉 Requires spatial arrangement and direction understanding.

2. Floor/Building Puzzle

- People living on different floors of a building.
- Often used to test vertical arrangement.

Example:
- 5 people live on 5 floors. X does not live on the top floor. Only two people live between X and Y. Who lives on the third floor?
👉 Visual tables help organize floors and names.

3. Scheduling Puzzle

- Assigning people or events to time slots, days, or weeks.

Example:
- Seven professors lecture from Monday to Sunday. A lectures after B but before C. No lectures on Thursday and Saturday. When does A lecture?
👉 Use tables or timelines for clarity.

4. Comparison and Ranking Puzzles

- Ranking based on height, weight, marks, etc.

Example:
- Among five students, R is taller than only T. S is taller than R but shorter than P. Who is the tallest?
👉 Focus on comparison chains.

5. Blood Relation Puzzle

- Establishing family relationships using clues.

Example:
- A is the son of B. C is B’s sister. D is C’s daughter. How is A related to D?
👉 Requires drawing family trees.

6. Direction and Distance Puzzle

- Based on movements in different directions.

Example:
- A walks 10 meters North, then turns right and walks 5 meters. Then he turns left and walks 5 meters. Where is he from his starting point?
👉 Requires mapping and visualization.

7. Mathematical/Logical Puzzles

- Number and symbol puzzles.

Example:
- Find the missing number in the series: 2, 6, 12, 20, ?
👉 Tests pattern recognition and arithmetic logic.

🛠️ General Strategy to Solve Puzzle-Based Reasoning Questions

Step-by-Step Approach

• 🔸 Step 1: - Read and Understand All Clues
  - Don’t skip any clue.
  - Underline or note key points.
• 🔸 Step 2: - Categorize the Information
  - Identify people, objects, places, positions, or days involved.
• 🔸 Step 3: Create a Visual Structure
  Use:
  • - Tables
  • - Boxes
  • - Arrows
  • - Grids
  to arrange the data.
• 🔸 Step 4: Use Elimination
  - Strike off impossible combinations or positions.
• 🔸 Step 5: Verify Clues One by One
  - Ensure all clues are satisfied before finalizing your answer.
• 🔸 Step 6: Practice Under Timed Conditions
  - Many puzzles become easier with speed and accuracy built through practice.

📘 Extended Example with Detailed Solution

❓ Puzzle Question:

Six people – A, B, C, D, E, and F – are sitting in a straight line facing north.

• • A is third to the right of F
• • B is to the immediate left of E
• • C is not sitting at any end
• • D is sitting between A and C

✅ Step-by-Step Analysis:

1. • Total seats = 6 (numbered 1 to 6 from left to right)
2. • "A is third to the right of F" → A is 3 positions to the right of F → Try F at position 1 → A at position 4
3. • F _ _ A _ _
4. • "B is to the immediate left of E" → B must be just before E → Try placing them later
5. • "C is not sitting at any end" → C cannot be at positions 1 or 6
6. • "D is sitting between A and C" → A – D – C or C – D – A must be in order
7. • Try placing: F at 1, A at 4 → Try D at 3, C at 2 → C is not at an end ✅
8. • Now E and B can be at 5 and 6 (E at 6, B at 5) → B is to immediate left of E ✅

Final arrangement:

• F
• C
• D
• A
• B
• E

Check all:

• • A is third to right of F ✅
• • B is to immediate left of E ✅
• • C is not at end ✅
• • D is between A and C ✅

Answer: F, C, D, A, B, E
