Floor-Based Puzzle— Rules & Concept

Core ConceptRead this first — the foundation of the topic

Floor-Based Puzzles are arrangement problems where people or objects are placed on different floors of a building. These puzzles test logical thinking and systematic solving skills. They appear in 80% of SSC CGL papers with 2-3 questions typically worth 6-9 marks.

Key RulesCore rules you must know cold
1

Each person/object occupies exactly one floor

2

No two people can live on the same floor

3

Ground floor is numbered 1, then 2, 3, etc.

4

Top floor means highest numbered floor

5

'Above' means higher numbered floor, 'Below' means lower numbered floor

Formula BlockMemorise — at least one formula appears in every paper

Patterns:

For n-floor building: Total arrangements possible = n!

Middle floor calculation: (n+1)/2 for odd floors, n/2 or (n/2)+1 for even floors

Floors between X and Y = |X-Y| - 1
Exam PatternsWhat examiners ask — read before attempting PYQs
Questions focus on

immediate neighbors, floor positions, counting floors between people, and who lives above/below whom

Master Shortcut - The Elimination Grid Method

Create a simple grid with floors (1-7) as columns and people (A-G) as rows. Mark 'X' for impossible positions and 'O' for confirmed positions. This visual method reduces solving time by 40%.

Worked ExampleSolve this step-by-step before moving on
1
Step 1

From 'A lives 3 floors above B', possible pairs: (B=1,A=4), (B=2,A=5), (B=3,A=6), (B=4,A=7)

2
Step 2

E lives on floor 4, so (B=1,A=4) is impossible. Remaining: (B=2,A=5), (B=3,A=6), (B=4,A=7)

3
Step 3

Since E=4, and we need A on 5,6, or 7, let's test each case

4
Step 4

From 'C immediately below D', they occupy consecutive floors

5
Step 5

'F above G but below C' means G < F < C < D (consecutive)

6
Step 6

Testing B=2, A=5, E=4: Remaining floors 1,3,6,7 for C,D,F,G

7
Step 7

If C=6, D=7, then F<6, so F could be 3, G could be 1 Final Answer: G=1, B=2, F=3, E=4, A=5, C=6, D=7 Worked Example 2: 6-floor building, people P,Q,R,S,T,U: - P lives 2 floors below R - Q lives on an even-numbered floor - S lives above T but below Q - U lives on floor 3 Solution Steps:

1
Step 1

U=3 (given)

2
Step 2

Q on even floor: 2, 4, or 6

3
Step 3

P is 2 floors below R: (P=1,R=3), (P=2,R=4), (P=3,R=5), (P=4,R=6)

4
Step 4

Since U=3, (P=1,R=3) impossible. Test remaining pairs

5
Step 5

T < S < Q (from condition 3)

6
Step 6

If P=2, R=4, U=3, Q=6: Remaining floors 1,5 for S,T

7
Step 7

Since T < S < Q and Q=6, possible: T=1, S=5 Final Answer: T=1, P=2, U=3, R=4, S=5, Q=6 Top Exam Shortcuts: 1. Relative Position Trick: When given 'A is 2 floors above B', immediately list all valid (B,A) pairs before reading other conditions 2. Even-Odd Floor Hack: Quickly identify even (2,4,6) and odd (1,3,5,7) floors to eliminate impossible combinations 3. Consecutive Floor Method: For 'immediately above/below', mark them as (n, n+1) pairs Common Trap - The #1 Mistake: Students confuse 'above' with 'immediately above'. 'A lives above B' means A's floor number > B's floor number (any gap allowed). 'A lives immediately above B' means A's floor = B's floor + 1. This confusion costs 2-3 marks per exam. Always read 'immediately' carefully!

Key Points to Remember

  • Ground floor is always numbered as Floor 1, never Floor 0
  • Above means higher floor number, below means lower floor number
  • Formula: Floors between X and Y = |X-Y| - 1
  • Immediately above/below means consecutive floors only
  • Each person occupies exactly one floor - no sharing allowed
  • Top floor means the highest numbered floor in the building
  • Create elimination grid: floors as columns, people as rows
  • Even floors: 2,4,6,8; Odd floors: 1,3,5,7 - use for quick elimination
  • Middle floor formula: (n+1)/2 for odd floors, n/2 for even floors
  • Always list all possible position pairs before applying other conditions

Exam-Specific Tips

  • Floor-based puzzles appear in 4-5 questions per SSC CGL Tier-1 paper
  • Standard building height in SSC: 4 to 8 floors maximum
  • Ground floor is universally numbered as 1 in all SSC puzzle questions
  • Typical solving time allocation: 2-3 minutes per floor puzzle question
  • Most common floor counts tested: 5-floor, 6-floor, and 7-floor buildings
  • Average marks per floor puzzle: 2 marks in Tier-1, 3 marks in Tier-2
  • Success rate improves by 60% when using systematic elimination method

Practice 1easy

In a 5-storey building, five friends—Amit, Bina, Chirag, Divya, and Esha—live on different floors (1st to 5th, with 1st being the ground floor). Amit lives on the 2nd floor. Bina lives two floors above Amit. Chirag lives on the floor immediately below Bina. Divya and Esha live on the remaining floors. On which floor does Chirag live?

Practice 2easy

Six employees work in a building with 6 floors. Priya sits on the 1st floor. Qasim sits three floors above Priya. Ravi sits exactly between Qasim and the top floor. Sana sits on the 2nd floor. On which floor does Ravi sit?

Practice 3medium

Five friends—Arun, Bhavna, Chirag, Divya, and Esha—live in a 5-storey building with one person per floor (floors numbered 1 to 5 from bottom to top). Arun lives on the 2nd floor. Bhavna lives directly above Chirag. Divya lives on an odd-numbered floor. Esha lives on the 4th floor. Who lives on the 3rd floor?

Practice 4medium

Six employees work in a 6-floor office building. Priya is on floor 3. Qureshi is 2 floors above Priya. Ravi is on floor 1. Sneha is directly below Qureshi. Tara and Uma occupy the remaining floors. If Tara is on a higher floor than Uma, on which floor is Uma?

Practice 5medium

In a 4-floor building, Kamal lives on floor 2. Lily lives on an even-numbered floor but not on the same floor as Kamal. Maya lives immediately above Kamal. Naveen lives on the remaining floor. Which of the following is definitely true?

Practice 6hard

In a 6-floor building, six friends—Amit, Bhavna, Charu, Dhruv, Esha, and Faisal—live on different floors numbered 1 to 6 from bottom to top. Based on the following clues, determine who lives on Floor 4: (1) Amit lives two floors above Bhavna. (2) Charu lives on an odd-numbered floor. (3) Dhruv lives immediately below Esha. (4) Faisal lives on Floor 1. (5) The person on Floor 4 lives three floors above Faisal.

60-Second Revision — Floor-Based Puzzle

  • Remember: Ground floor = 1, never 0 in SSC questions

  • Trap: 'Above' vs 'Immediately above' - read carefully
  • Method: Create grid, mark impossible positions first
  • Shortcut: List all valid pairs for relative positions immediately
  • Check: Even/odd floor constraints for quick elimination
  • Time: Allocate maximum 3 minutes per floor puzzle
