Puzzles for SBI Clerk — Floor, Box, Scheduling & Arrangement Types

advanced 22 min read

Concept

Puzzles in SBI Clerk Reasoning are constraint-satisfaction problems. You are given a set of entities (people, books, floors, boxes) and a set of relational clues. Your job is to find the unique valid arrangement that satisfies every clue simultaneously.

Think of it exactly like a Sudoku grid. In Sudoku, the rule is no digit repeats in a row, column, or box — and partial information lets you deduce the rest. In a reasoning puzzle, the rules are the clues themselves. Each clue eliminates possibilities until only one configuration survives.

Here is the critical mental shift that separates 90-percentile scorers from average ones: you are not looking for the arrangement — you are eliminating all wrong arrangements. Every clue is a scissors cut. Your job is to keep cutting until one possibility remains.

Puzzles appear in clusters in SBI Clerk — you solve one set of clues, then answer four to five questions from it. This means getting the arrangement right is a leveraged investment: spend two minutes solving it correctly and you bank four to five marks. Rush it, get one entity wrong, and you may lose all five questions.

The puzzle types you will face:

The analogy that helps most students: think of each clue as a LEGO connector. Individual connectors do nothing alone, but combine three or four of them and the structure locks into place. Your skill is finding which clue to start with (the one that gives the most definitive placement) and which connectors to chain next.


Deep Dive

Step 1 — Scan Before You Draw

Before touching your answer sheet, read all clues once. Identify:

  1. Anchor clues — clues that give an absolute position (e.g., "D sits at one end", "F is on the 3rd floor", "A is the tallest").
  2. Elimination clues — clues that say what someone is NOT (e.g., "C does not sit next to A").
  3. Relative clues — clues that give ordering (e.g., "P is above Q", "A is taller than B").

Always start with anchor clues. They fix one entity, which cascades into others.

Step 2 — Draw the Correct Template

For each puzzle type, draw the right visual before writing anything:

| Puzzle Type | Template | |---|---| | Linear (one row) | _ _ _ _ _ with position numbers 1–5 | | Linear (two rows facing) | Two parallel rows with arrows showing direction | | Floor | Vertical column, top floor at top | | Box/Stack | Same as floor — vertical column | | Day/Schedule | Horizontal row: Mon Tue Wed Thu Fri Sat Sun | | Tabular | Grid with persons as rows, attributes as columns |

Getting the template right is not a detail — it is the foundation. Wrong template = wrong reasoning.

Step 3 — Chain Clues Systematically

Here's how professional solvers work:

  1. Write anchor clues directly into the template.
  2. For relative clues, write them as inequality chains — e.g., D > C > A > E > B for a height ranking.
  3. For compound relative clues ("P is above Q AND R is below S AND Q is above S"), write the full chain before putting anything in the template: P > Q > S > R.
  4. When stuck, use case-branching — assume one entity occupies a position, check if contradiction arises, then accept or reject.

Step 4 — Handle Multi-Variable Puzzles

Tabular puzzles have two or more attributes per person. Example: 5 people, 5 floors, 5 professions, 5 cities. Work one attribute dimension at a time. Solve floors first using floor-specific clues, then map professions using profession clues, then cities. Never try to solve all three simultaneously — your working memory will overload.

Step 5 — Verify Before Moving to Questions

Once your arrangement is complete, scan every clue one more time. This takes 20 seconds and catches errors that cost you five marks. Do not skip this.

Ranking Puzzles — Build the Chain

For height/age/score rankings, convert all clues to a single linear order. Use > notation consistently:

The chain tells you the full ranking directly. No need to "think through" it repeatedly.

Coding-in-Puzzle Hybrids

Some puzzles involve coded conditions ("P sits two places to the right of the person who likes mango"). Decode the condition first, write it in plain relational form, then add it to your clue set.

Clock-Angle Puzzles (Scheduling-adjacent)

Clock puzzles are a calculation subtype, not a pure arrangement. The key formula:


Memory Tricks & Shortcuts

patternChain-First for Rankings

Before drawing anything, convert all ranking clues into one inequality chain on the side of your rough work. Example: clues say "A > B", "C > A", "D is tallest", "E: A > E > B". Chain: D > C > A > E > B. You now read off answers to "who is shortest" (B) and "who is third" (A) in zero additional thinking. Standard method (re-reading clues per question): 30–40 seconds per question. Chain method: 5 seconds per question after the chain is built.

patternPosition Formula for Row Problems

When a person is Xth from the left and Yth from the right in a row, total count = X + Y - 1. This is a one-step formula — no drawing required. Example: 7th from left, 12th from right → 7 + 12 - 1 = 18. Standard method (drawing the row and counting): 45 seconds. Formula method: 5 seconds. Use this formula whenever you see "from left" and "from right" in the same clue.

eliminationAnchor-Then-Chain for Stacking Puzzles

In above/below (books, boxes, floors) puzzles, find the entity mentioned in the most clues — it is usually the pivot. Fix it conceptually first, then attach entities above and below it. Example: P > Q, R < S, Q > S → Q is mentioned in two clues, making it the pivot. From Q > S and R < S: Q > S > R. From P > Q: P > Q > S > R. Four entities placed in four steps, no case-branching needed. Versus random-clue-order approach: typically requires 2–3 case branches, adding 60–90 seconds.

eliminationCode-Comparison for Coding Puzzles

When solving a code language puzzle, write the three given phrases in a table, then circle common words and their corresponding common codes. Words appearing in exactly two phrases share one code — match them. Words appearing in only one phrase: their code is the leftover. This visual comparison eliminates guesswork entirely. Standard method (reading and re-reading): 60–90 seconds. Table-comparison method: 20–30 seconds.

patternClock Angle Without Memorising Two Formulas

Use a single formula: Angle = |30H - 5.5M| where H is the hour and M is the minutes. At 3:15 → |30×3 - 5.5×15| = |90 - 82.5| = 7.5°. No need to compute hour-hand and minute-hand angles separately and then subtract. This collapses two steps into one. Standard two-formula method: 4 steps, ~40 seconds. Single-formula method: 1 step, ~10 seconds.


Fast-Solving Framework

Use this decision tree in the exam hall:

Step 1 — What type is this?

Step 2 — Find the anchor.

Step 3 — Build the chain or grid.

Step 4 — Verify all clues (20 seconds).

Step 5 — Answer questions in order.

If a puzzle has six or more clues and two variables, budget three minutes for solving. If four or fewer clues and one variable, budget ninety seconds maximum.


Solved PYQs

Why this question: This is a pure ranking puzzle — the most common puzzle subtype in SBI Clerk prelims. If you cannot chain five entities, you will drop marks on entire sets.

Previous Year Questionपिछले वर्ष का प्रश्न
Five students A, B, C, D, E have different heights. A is taller than B but shorter than C. D is the tallest. E is shorter than A but taller than B. Who is the shortest?
पाँच छात्र A, B, C, D, E की अलग-अलग ऊँचाई है। A, B से लंबा है लेकिन C से छोटा है। D सबसे लंबा है। E, A से छोटा है लेकिन B से लंबा है। सबसे छोटा कौन है?
  1. A
  2. B
  3. C
  4. E
  1. A
  2. B
  3. C
  4. E
Solutionसमाधान
From the given information: D is tallest, A is taller than B but shorter than C, E is shorter than A but taller than B. So the order is: D > C > A > E > B. Therefore, B is the shortest.
दी गई जानकारी से: D सबसे लंबा है, A, B से लंबा है लेकिन C से छोटा है, E, A से छोटा है लेकिन B से लंबा है। तो क्रम है: D > C > A > E > B। इसलिए, B सबसे छोटा है।

Solving path: Read all clues. D is tallest (anchor — write D at top). "A > B but A < C" gives C > A > B. "E: A > E > B" inserts E between A and B. Chain: D > C > A > E > B. Shortest = B. Time with chain method: under 20 seconds.


Why this question: Linear row problems with "from left / from right" appear in almost every SBI Clerk paper. The position formula eliminates the most common error (forgetting to subtract 1).

Previous Year Questionपिछले वर्ष का प्रश्न
In a row of children, Ravi is 7th from the left and 12th from the right. How many children are there in the row?
बच्चों की एक कतार में, Ravi बाईं ओर से 7वें और दाईं ओर से 12वें स्थान पर है। कतार में कुल कितने बच्चे हैं?
  1. 18
  2. 19
  3. 20
  4. 17
  1. 18
  2. 19
  3. 20
  4. 17
Solutionसमाधान
If Ravi is 7th from left, there are 6 children to his left. If he is 12th from right, there are 11 children to his right. Total children = 6 (left) + 1 (Ravi) + 11 (right) = 18 children.
यदि रवि बाएं से 7वां है, तो उसके बाएं 6 बच्चे हैं। यदि वह दाएं से 12वां है, तो उसके दाएं 11 बच्चे हैं। कुल बच्चे = 6 (बाएं) + 1 (रवि) + 11 (दाएं) = 18 बच्चे।

Solving path: Apply formula: Total = 7 + 12 - 1 = 18. That is it. No drawing needed. If you drew a row, you likely got the same answer but spent 30–40 extra seconds.


Why this question: Stack/above-below puzzles use the same chain logic as ranking puzzles. This question tests whether you can merge three separate relative clues into one unified order.

Previous Year Questionपिछले वर्ष का प्रश्न
Four books P, Q, R, S are placed on a shelf. P is above Q, R is below S, Q is above S. Which book is at the bottom?
चार किताबें P, Q, R, S एक शेल्फ पर रखी हैं। P, Q के ऊपर है, R, S के नीचे है, Q, S के ऊपर है। सबसे नीचे कौन सी किताब है?
  1. P
  2. Q
  3. R
  4. S
  1. P
  2. Q
  3. R
  4. S
Solutionसमाधान
Given: P is above Q, R is below S, Q is above S. From Q above S and P above Q, we get P > Q > S. From R below S, we get S > R. Combining: P > Q > S > R. Therefore, R is at the bottom.
दिया गया: P, Q के ऊपर है, R, S के नीचे है, Q, S के ऊपर है। Q, S के ऊपर और P, Q के ऊपर से, हमें P > Q > S मिलता है। R, S के नीचे से, हमें S > R मिलता है। संयोजन: P > Q > S > R। इसलिए, R सबसे नीचे है।

Solving path: P > Q (given). R < S (given). Q > S (given). Chain the last two: Q > S > R. Merge with first: P > Q > S > R. Bottom = R. Verify: R is below S (check), Q is above S (check), P is above Q (check). Done in four logical steps.


Why this question: Code-language puzzles appear as standalone questions AND as embedded conditions in tabular puzzles. The comparison-table method is universal.

Previous Year Questionपिछले वर्ष का प्रश्न
In a certain code language, 'ka na ta' means 'you are good', 'sa ka pa' means 'he is good', and 'na da sa' means 'you can he'. What does 'ta' mean?
एक खास कोड भाषा में, 'ka na ta' का मतलब है 'you are good', 'sa ka pa' का मतलब है 'he is good', और 'na da sa' का मतलब है 'you can he'। तो 'ta' का मतलब क्या है?
  1. you
  2. are
  3. good
  4. he
  1. you
  2. are
  3. good
  4. he
Solutionसमाधान
From the given codes: 'ka na ta' = 'you are good', 'sa ka pa' = 'he is good', 'na da sa' = 'you can he'. 'ka' means 'good' (common in first two), 'na' means 'you' (common in first and third), 'sa' means 'he' (common in second and third). Therefore, 'ta' means 'are'.
दिए गए कोड से: 'ka na ta' = 'you are good', 'sa ka pa' = 'he is good', 'na da sa' = 'you can he'। 'ka' का अर्थ 'good' है (पहले दो में सामान्य), 'na' का अर्थ 'you' है (पहले और तीसरे में सामान्य), 'sa' का अर्थ 'he' है (दूसरे और तीसरे में सामान्य)। इसलिए, 'ta' का अर्थ 'are' है।

Solving path: Write a comparison table. "ka na ta" = "you are good". "sa ka pa" = "he is good". Common: ka = good (appears in both, paired with "good"). "na da sa" = "you can he". Common with first: na = you. Common with second: sa = he. Leftover in first phrase: ta = are. Answer: "are".


Why this question: Linear arrangement with directional conditions is a core puzzle subtype. This question tests whether you can manage multiple partial constraints simultaneously.
