Logical Reasoning and Puzzles for Banking Exams: Approach and Practice

Reasoning is the highest-scoring section in Banking exams for those who practice it systematically, and the most frustrating section for those who don't. The gap between a well-prepared aspirant and an average one is wider here than in any other section.

In IBPS PO Prelims, you get 35 questions in 20 minutes. In Mains, it's 40 questions in 40 minutes. The section is dominated by puzzles and seating arrangements — together, they constitute 60-70% of the marks. If you can crack puzzles consistently, you've essentially secured a good Reasoning score.

Topic Weightage in Banking Reasoning

IBPS PO / SBI PO Prelims (35 Questions, 20 Minutes)

Topic	Questions	Priority
Puzzles & Seating Arrangement	15–20	Highest
Syllogism	3–5	High
Inequality	3–5	High
Coding-Decoding	3–5	Medium
Blood Relations	2–3	Medium
Direction Sense	1–2	Low
Order & Ranking	1–2	Low
Alphabet/Number Series	3–5	Medium

IBPS PO / SBI PO Mains (40 Questions, 40 Minutes)

Puzzles and seating arrangements dominate even more — typically 20–25 questions out of 40. The complexity increases: instead of single-parameter puzzles, you'll see 2-3 parameters (person-floor-department, person-day-city-color).

Puzzle Types and How to Approach Each

Linear Seating Arrangement

People sit in a row, facing north or south (or both rows facing each other).

Approach:

1. Draw the arrangement on paper first. Always. Don't try to hold it in your head.
2. Start with definite clues — "A sits at one end," "B faces north."
3. Then use relative clues — "C sits second to the left of A."
4. Finally, use negative clues — "D does not sit adjacent to B."

Practice tip: Start with 5-person single-row arrangements. Once you can solve them in 3 minutes, move to 8-person rows, then double rows.

Circular Seating Arrangement

People sit around a circular table, facing center or outside.

Approach:

1. Fix one person's position (the one with the most definite information) and build around them.
2. "Left" and "right" in circular arrangements depend on facing direction. If facing center, the person to your left is clockwise. If facing outside, it's counterclockwise.
3. Draw it. Every single time.

Floor-Based Puzzles

8 people live on floors 1–8 of a building, with additional parameters (profession, city, etc.).

Approach:

1. Draw a table: floor numbers on one side, columns for each parameter.
2. Start with floor-specific clues: "A lives on floor 5," "B lives above C."
3. Fill in definite positions, then use elimination for the rest.
4. If stuck, consider both possibilities and see which one doesn't lead to a contradiction.

Day/Month-Based Scheduling

People perform activities on different days of the week or different months.

Same approach as floor puzzles — tabular format, definite clues first, elimination second.

Box/Object-Based Puzzles

Boxes stacked in order, objects in compartments, etc. These are variations of floor-based puzzles.

Syllogism

Syllogism questions give you 2–3 statements and ask which conclusions follow. There are two approaches:

Venn Diagram Method (Recommended for Beginners)

Draw circles for each category. "All A are B" means A's circle is inside B's. "Some A are B" means circles overlap. "No A is B" means circles don't touch.

After drawing all statements, check if each conclusion is necessarily true from the diagrams.

Limitation: With 3+ statements, you might need to draw multiple possible diagrams, which takes time.

Analytical Method (Faster Once Mastered)

Learn these rules:

• All + All = All (All A are B + All B are C → All A are C)


• All + No = No (All A are B + No B is C → No A is C)


• Some + All = Some (Some A are B + All B are C → Some A are C)


• Some + Some = No conclusion


• Some + No = Some Not (Some A are B + No B is C → Some A are not C)

For "possibility" questions: If a conclusion is not definitely true, its possibility is usually true unless contradicted by a definite statement.

Coding-Decoding

The new pattern in Banking exams uses sentence-based coding where full sentences are coded and you deduce individual word codes.

Approach:

1. Compare sentences that share common words — their common codes represent those shared words.
2. Process of elimination narrows down each word's code.
3. Write each deduction down systematically.

---

Inequality

Questions give a chain of relationships: A > B ≥ C = D < E ≤ F.

Approach:

1. Combine the chain fully.
2. For each conclusion, check if the path from one variable to another maintains a consistent direction (all ≥ or all ≤).
3. If there's an "=" anywhere in a strictly greater/less chain, the conclusion fails.

Speed tip: This topic is the fastest to solve in the entire Reasoning section. With practice, each question takes 15–20 seconds. Don't leave these undone in the exam.

Blood Relations

Key technique: Draw a family tree as you read the clue. Use standard notation:

• Horizontal line = married couple
• Vertical line = parent-child
• Male = square or + sign, Female = circle or - sign

Most blood relation questions can be solved in under a minute with a proper diagram.

Critical Mistakes in Reasoning

1. Not drawing diagrams. The single biggest reason people get puzzles wrong. Your working memory can hold 4–7 items. Puzzles have 8–10 elements with multiple parameters. You physically cannot solve them without writing. 2. Spending too long on one puzzle. If a puzzle isn't cracking after 5 minutes, leave it. Come back if you have time. Spending 10 minutes on one puzzle while leaving 5 easy Inequality questions unattempted is terrible exam strategy. 3. Ignoring negative clues. "A does not sit adjacent to B" is often the clue that cracks the puzzle open. Beginners tend to focus only on positive placement clues and ignore restriction clues. 4. Not practicing enough variety. If you've only practiced linear arrangements, a circular arrangement in the exam will throw you off even though the logic is similar. Expose yourself to all puzzle types.

Exam Day Approach for Reasoning

First 2 minutes: Scan the entire section. Identify Inequality and Syllogism questions — solve these first (fastest, highest accuracy). Next 3–4 minutes: Blood Relations, Coding-Decoding, Direction Sense. Remaining time: Puzzles. Start with the puzzle that looks most solvable (more definite clues = easier to start). If you attempt 3 out of 4 puzzle sets accurately, that's a strong performance.
