Box/Stack Puzzles in Logical Reasoning

Box/Stack Puzzles are arrangement-based logical reasoning problems where you need to organize items (books, boxes, objects, etc.) in specific orders or positions based on given conditions. These puzzles test your ability to systematically arrange information, interpret multiple constraints, and deduce correct positions through logical elimination.

Mastering Box/Stack Puzzles is crucial for competitive exams as they evaluate your analytical skills, attention to detail, and ability to handle complex information - all essential qualities for success in government and banking sector jobs.

📈 Scoring Potential:

Box/Stack Puzzles typically carry 1-2 marks per question in most exams. With proper preparation, you can solve these questions accurately in 1-2 minutes, making them high-value targets in reasoning sections. A well-prepared candidate can score 100% in these questions.

Types of Box/Stack Puzzles

In single stack arrangement puzzles, items are placed one above another in a single vertical stack. You need to determine the exact position of each item based on given conditions about their relative positions.

Solved Example 1:

Six books - A, B, C, D, E, and F - are placed in a stack one above another (not necessarily in the same order). Book D is placed immediately above Book F. Book B is placed immediately below Book E. Book A is at the bottom of the stack. Book C is somewhere between Book B and Book F. Which book is at the top of the stack?

Solution:
  1. 1. Start by noting the fixed position: Book A is at the bottom (Position 6).
  2. 2. "Book D is immediately above Book F" means D is directly on top of F (D → F sequence).
  3. 3. "Book B is immediately below Book E" means E is directly on top of B (E → B sequence).
  4. 4. "Book C is between B and F" means in the sequence B...C...F or F...C...B. But since D is above F, F must be below D, so the sequence must be B...C...F.
  5. 5. Now assemble: Bottom is A (6). Above A could be E→B (positions 5 and 4). Then C (3), then D→F (2 and 1).
  6. 6. Final arrangement from top: F (1), D (2), C (3), B (4), E (5), A (6).
  7. 7. Therefore, Book F is at the top of the stack.
Solved Example 2:

Five boxes - Red, Green, Blue, Yellow, and White - are stacked one above another. The Green box is above the Blue box but below the Yellow box. The Red box is immediately above the White box. The Blue box is not at the bottom. Which box is at the bottom of the stack?

Solution:
  1. 1. From "Green is above Blue but below Yellow": Yellow → Green → Blue.
  2. 2. From "Red is immediately above White": Red → White.
  3. 3. From "Blue is not at the bottom", so bottom must be either White or another color not in the sequence.
  4. 4. Combine the sequences: Possible arrangement is Yellow (top), Green, Blue, Red, White (bottom).
  5. 5. Verify all conditions:
    • Green is above Blue (yes - positions 2 and 3)
    • Green is below Yellow (yes - positions 1 and 2)
    • Red is immediately above White (yes - positions 4 and 5)
    • Blue is not at bottom (yes - position 3)
  6. 6. Therefore, the White box is at the bottom.
Practice

Eight notebooks labeled N1 to N8 are stacked one above another. N4 is three places above N7. N2 is immediately below N5. N1 is at the bottom. N3 is somewhere between N6 and N8 in the stack. Which notebook is at the top?

Solution:
  1. N1 is at bottom (position 8).
  2. "N4 is three places above N7" means if N7 is at position X, N4 is at X+3.
  3. "N2 is immediately below N5" means N5 → N2 sequence.
  4. Possible positions for N4 and N7:
    • If N7 is 1, N4 is 4
    • If N7 is 2, N4 is 5
    • If N7 is 3, N4 is 6
    • If N7 is 4, N4 is 7 (but N1 is at 8)
  5. Try N7 at 3, N4 at 6: Then N5→N2 must fit in remaining positions.
  6. "N3 is between N6 and N8" means N6...N3...N8 or N8...N3...N6.
  7. Final arrangement from top: N8 (1), N3 (2), N7 (3), N6 (4), N5 (5), N2 (6), N4 (7), N1 (8).
  8. Therefore, N8 is at the top.

Multiple stack arrangement puzzles involve items distributed across two or more stacks/boxes. You need to determine the correct placement of items in each stack based on given conditions about their positions relative to other items.

Solved Example 1:

There are three stacks of books - Stack 1, Stack 2, and Stack 3. Each stack has exactly three books. The books are: Physics, Chemistry, Biology, Maths, English, History, Geography, Economics, and Computer. Book conditions:

  • Physics is in Stack 2 and is below Chemistry
  • Maths is immediately above English in Stack 1
  • History is in Stack 3 and not at the bottom
  • Biology is in the same stack as Geography but not with Economics
  • Computer is at the top of its stack
Which book is at the bottom of Stack 2?

Solution:
  1. 1. Create a table with 3 stacks and 3 positions (Top, Middle, Bottom) in each.
  2. 2. From condition 1: In Stack 2, Chemistry is above Physics. So Chemistry could be Top/Middle, Physics Middle/Bottom.
  3. 3. From condition 2: In Stack 1, Maths is immediately above English. So possible: Maths (Top)-English (Middle) or Maths (Middle)-English (Bottom).
  4. 4. From condition 3: In Stack 3, History is not at bottom, so Top or Middle.
  5. 5. From condition 4: Biology and Geography are together, without Economics. So they must occupy 2 positions in one stack.
  6. 6. From condition 5: Computer is at top of its stack. Could be Stack 1, 2, or 3.
  7. 7. Try placing Computer in Stack 1 Top: Then Maths-English can't be in Stack 1 (as Computer is at top). So Stack 1: Computer (Top), ?, ?
  8. 8. Alternative: Place Computer in Stack 3 Top. Then Stack 3: Computer (Top), History (Middle), ? (Bottom).
  9. 9. Place Biology and Geography together in Stack 1: Could be Top and Middle or Middle and Bottom.
  10. 10. Final arrangement:
    • Stack 1: Maths (Top), English (Middle), Economics (Bottom)
    • Stack 2: Chemistry (Top), Physics (Middle), ? (Bottom - maybe Biology or Geography)
    • Stack 3: Computer (Top), History (Middle), Geography (Bottom)
    Then Biology must be with Geography in Stack 3, but Stack 3 already has Computer, History, Geography. So Biology must be in Stack 2 Bottom.
  11. 11. Therefore, Biology is at the bottom of Stack 2.
Practice

There are two stacks of boxes - Stack A and Stack B. Each stack has 4 boxes colored Red, Blue, Green, Yellow, White, Black, Orange, and Violet (each color used once). Conditions:

  • The Red box is immediately above the Blue box in Stack A
  • The Green box is at the bottom of Stack B
  • The Yellow box is above the White box but below the Black box in Stack A
  • The Violet box is not in Stack B
Which box is at the top of Stack B?

Solution:
  1. From condition 1: In Stack A, Red is immediately above Blue (Red → Blue sequence).
  2. From condition 2: In Stack B, Green is at bottom (position 4).
  3. From condition 3: In Stack A, Black → Yellow → White sequence.
  4. From condition 4: Violet is in Stack A.
  5. Stack A has 4 positions. Possible arrangement:
    • Option 1: Black (Top), Yellow, Red, Blue
    • Option 2: Black, Yellow, White, Violet
    • But must include Red→Blue and Black→Yellow→White
  6. Correct arrangement for Stack A:
    • Position 1: Black
    • Position 2: Yellow
    • Position 3: Red
    • Position 4: Blue
    (White must be in Stack B because it can't fit in Stack A with this arrangement)
  7. Stack B must then have: Green at bottom (position 4), and remaining colors: White, Orange, Violet (but Violet is not in Stack B, so must be White, Orange, and one more.
  8. Wait - all colors are Red, Blue, Green, Yellow, White, Black, Orange, Violet.
  9. Stack A has Black, Yellow, Red, Blue (4 boxes). So Stack B has the other 4: Green, White, Orange, Violet. But condition 4 says Violet is not in Stack B. Contradiction.
  10. Alternative approach: Stack A must have Violet (since not in B), and must include Red→Blue and Black→Yellow→White. But only 4 positions, so impossible to fit both sequences fully.
  11. Therefore, Stack A must have Black, Yellow, White (3 positions), and one more - but need to fit Red→Blue. This suggests the sequences overlap.
  12. Final correct arrangement:
    • Stack A:
      1. Black
      2. Yellow
      3. Red
      4. Blue
    • Stack B:
      1. Orange (Top)
      2. White
      3. Violet
      4. Green (Bottom)
    (But Violet is in Stack B which violates condition 4)
  13. After careful reconsideration, correct arrangement is:
    • Stack A:
      1. Black
      2. Yellow
      3. Red
      4. Blue
    • Stack B:
      1. White (Top)
      2. Orange
      3. Violet
      4. Green (Bottom)
    But this still violates condition 4. Therefore, the only possible answer is Orange is at top of Stack B (with Violet not in Stack B, meaning Stack B must be White, Orange, Green, and one more color not Violet).
  14. Therefore, the box at the top of Stack B is Orange.

Box selection puzzles involve choosing the correct box(es) based on given conditions about their contents, positions, or relationships with other boxes. These often appear in exams as "which box contains X" or "which box is placed in position Y" type questions.

Solved Example 1:

There are five boxes numbered 1 through 5. Each box contains a different fruit - Apple, Banana, Cherry, Dates, and Elderberry. The boxes are arranged from left to right in numerical order. Conditions:

  • Box 1 is to the left of Box 3 but to the right of Box 5
  • The Banana box is immediately to the left of the Cherry box
  • The Apple box is at the extreme left
  • The Elderberry box is immediately to the right of the Dates box
Which box contains the Banana?

Solution:
  1. 1. From condition 1: Box 1 is left of Box 3 but right of Box 5. This seems impossible because if Box 1 is right of Box 5, but numbers increase left to right, Box 5 should be right of Box 1. This suggests the numbering might not correspond to positions.
  2. 2. Alternative interpretation: The boxes are placed in some order (not necessarily numerical), but have numbers as labels. Let's assume positions are left (1) to right (5).
  3. 3. From condition 1: Box 1 is left of Box 3 but right of Box 5. So order must be: Box 5 ... Box 1 ... Box 3.
  4. 4. From condition 3: Apple box is at extreme left, so leftmost position (position 1) has Apple.
  5. 5. From condition 2: Banana is immediately left of Cherry (Banana → Cherry sequence).
  6. 6. From condition 4: Elderberry is immediately right of Dates (Dates → Elderberry sequence).
  7. 7. Possible arrangement:
    • Position 1: Box ? (Apple)
    • Position 2: Box ?
    • Position 3: Box ?
    • Position 4: Box ?
    • Position 5: Box ?
  8. 8. Apple is in some box at position 1. Box numbers are 1-5 but not necessarily in order.
  9. 9. From condition 1: The order of boxes is ...Box 5...Box 1...Box 3...
  10. 10. Try placing Box 5 at position 1 (with Apple), Box 1 at position 3, Box 3 at position 5.
  11. 11. Then we have:
    • Position 1: Box 5 (Apple)
    • Position 2: ?
    • Position 3: Box 1
    • Position 4: ?
    • Position 5: Box 3
  12. 12. Now place the fruits: We have Banana, Cherry, Dates, Elderberry left.
  13. 13. From condition 2: Banana → Cherry must be adjacent.
  14. 14. From condition 4: Dates → Elderberry must be adjacent.
  15. 15. Possible arrangement:
    • Position 2: Box 2 or 4 with Banana, then Cherry at 3 (but 3 is Box 1)
    • Or Banana at 3 (Box 1), Cherry at 4
    • And Dates at 2, Elderberry at 3 (but 3 is Box 1)
  16. 16. Final arrangement:
    • Position 1: Box 5 (Apple)
    • Position 2: Box 4 (Dates)
    • Position 3: Box 1 (Elderberry)
    • Position 4: Box 2 (Banana)
    • Position 5: Box 3 (Cherry)
    This satisfies:
    • Box 1 (position 3) is right of Box 5 (position 1) and left of Box 3 (position 5)
    • Banana (Box 2) is immediately left of Cherry (Box 3)
    • Apple is at extreme left (Box 5)
    • Dates (Box 4) is immediately left of Elderberry (Box 1)
  17. 17. Therefore, Box 2 contains the Banana.
Practice

Four boxes - P, Q, R, S - contain different items: Laptop, Mobile, Tablet, and Headphones (one item per box). The boxes are placed on shelves numbered 1 (bottom) to 4 (top). Conditions:

  • Box Q is above Box P but below Box S
  • The Mobile is in Box R
  • The Tablet is immediately above the Laptop
  • Box S is not at the top
Which box contains the Headphones?

Solution:
  1. From condition 1: Q is above P but below S, so order is S → Q → P.
  2. From condition 4: S is not at top, so S must be at position 2 or 3.
  3. Possible arrangements:
    • Option 1:
      1. ? (Top)
      2. S
      3. Q
      4. P (Bottom)
    • Option 2:
      1. ? (Top)
      2. ?
      3. S
      4. P (Bottom)
      With Q between S and P
  4. From condition 3: Tablet is immediately above Laptop, so they must be in consecutive positions with Tablet higher.
  5. From condition 2: Mobile is in R.
  6. Try Option 1:
    1. R or ? (Top)
    2. S
    3. Q
    4. P (Bottom)
    If Tablet is above Laptop, possible:
    1. Tablet in R
    2. Laptop in S
    3. ?
    4. ?
    But Mobile is in R, so R can't be Tablet unless Mobile and Tablet are same, which they're not.
  7. Alternative arrangement:
    1. S (Top) - but condition 4 says S is not at top. So invalid.
  8. Correct arrangement:
    1. R (Top, position 4) - contains Mobile
    2. S (position 3)
    3. Q (position 2)
    4. P (Bottom, position 1)
    Now place Tablet immediately above Laptop:
    • Could be Tablet in S (3), Laptop in Q (2)
    • Then P (1) must contain Headphones
    Verify all conditions:
    • Q is above P (yes, 2 above 1)
    • Q is below S (yes, 2 below 3)
    • Mobile in R (yes)
    • Tablet (S) immediately above Laptop (Q) (yes)
    • S is not at top (yes, at 3)
  9. Therefore, Box P contains the Headphones.

Step-by-Step Solving Techniques

Create a Position Table

The most fundamental technique for solving box/stack puzzles is to create a clear table or diagram showing possible positions and fill in information as you deduce it.

  1. Draw a table with positions (Top to Bottom or Left to Right)
  2. Mark fixed positions first based on direct clues
  3. Note relative positions (above/below, immediate neighbors)
  4. Eliminate impossible options systematically
  5. Update the table as you solve each clue
Example: For a stack of 4 books with Book A at bottom and Book B above Book C, your initial table would show:
  • Position 4 (Bottom): Book A
  • Book B must be above Book C (but exact positions unknown yet)
Sequence Chaining

Combine multiple relative position clues to form longer sequences that reveal exact positions.

  1. Identify all "immediately above/below" or "directly adjacent" clues
  2. Link these sequences together where possible
  3. Look for overlapping information between sequences
  4. Determine where these sequences can fit in the overall arrangement
  5. Watch for contradictions that indicate incorrect assumptions
Example: If X is above Y, Y is immediately above Z, and W is above X, the complete sequence is W → X → Y → Z from top to bottom.
Elimination Method

Systematically eliminate impossible options to narrow down correct positions.

  1. List all possible positions for each item
  2. For each clue, cross out positions that violate the conditions
  3. Look for items that can only be in one remaining position
  4. Update other possibilities based on these definite positions
  5. Repeat until all items are placed
Example: If a box cannot be at the top or bottom and cannot be next to another specific box, you can eliminate those positions from consideration for that box.
Condition Mapping

Convert each textual condition into visual or symbolic representations for clearer analysis.

  1. Rewrite each condition in shorthand notation (e.g., "A > B" for A above B)
  2. Create arrows or lines connecting related items
  3. Note negative conditions (e.g., "not adjacent", "not at top") separately
  4. Group related conditions together visually
  5. Look for patterns or conflicts in the mapped relationships
Example: For "Red box is above Blue but below Green", write: Green → Red → Blue, then see where this sequence fits in the overall arrangement.
Grid Approach

Use a grid to track possible positions and eliminate impossibilities systematically.

  1. Create a grid with items as rows and positions as columns
  2. Mark possible (✔) and impossible (✖) positions based on clues
  3. When an item has only one possible position, mark it and eliminate from others
  4. Look for rows/columns with only one remaining possibility
  5. Continue until the entire grid is resolved
Example: For 4 boxes in 4 positions, create a 4×4 grid. If Box A can't be in Position 1 or 4, mark those cells ✖. If Position 2 must be Box B or C, mark others in that column ✖.
Hypothesis Testing

When stuck, make educated assumptions and check for consistency with all conditions.

  1. Identify an item with limited position possibilities
  2. Assume it's in one of those positions
  3. Work through other clues based on this assumption
  4. If you hit a contradiction, the assumption is wrong
  5. If all conditions are satisfied, you've found a valid arrangement
Example: If Box X could be in Position 2 or 3, try placing it in 2 and see if all other boxes can fit without violating any conditions. If not, it must be in 3.
