Important Strategies and Shortcuts
General Puzzle-Solving Framework
STEP 1: Read all statements carefully
STEP 2: Identify fixed/absolute information first
STEP 3: Create a visual representation
STEP 4: Fill in direct deductions
STEP 5: Use elimination for uncertain positions
STEP 6: Cross-verify with all conditions
Quick Reference for Seating Arrangement
| Statement | Interpretation |
|---|---|
| A is 3rd to left of B | A ← ← ← B (skip 2 positions) |
| A is adjacent to B | A and B are next to each other |
| A sits opposite to B | Exactly half circle apart |
| A sits between B and C | B-A-C or C-A-B |
Comparison Notation
Use symbols for quick notation:
- A > B (A is taller/heavier/more than B)
- A < B (A is shorter/lighter/less than B)
- Chain: A > B > C implies A > C
Practice Questions
Set 1: Linear Seating Arrangement
Directions (Q.1-5): Eight persons A, B, C, D, E, F, G, and H sit in a row facing north.
Given:
- A sits third to the left of D
- Only two persons sit between A and F
- G sits second to the right of F
- E sits at one of the extreme ends
- B sits to the immediate left of C
- C is not a neighbor of D
- H sits somewhere to the left of B
Question 1 (Easy): Who sits at the extreme right end?
Solution: Working through the constraints:
- A _ _ D arrangement
- With two persons between A and F
- G positioned relative to F
- E at an extreme
After systematic elimination:
Final Arrangement: E(1), F(2), H(3), G(4), A(5), B(6), C(7), D(8)
Question 2 (Easy): Who sits immediately to the left of A?
Solution: From the arrangement, G is at position 4 and A is at position 5.
Question 3 (Medium): How many persons sit between F and C?
Solution: F is at position 2, C is at position 7. Positions between: 3, 4, 5, 6 (H, G, A, B)
Question 4 (Medium): Four of the following five are alike in a certain way. Which one does not belong? a) A-D b) B-C c) F-G d) H-G e) G-A
Solution: Checking adjacency:
- A-D: positions 5 and 8 (not adjacent)
- B-C: positions 6 and 7 (adjacent)
- F-G: positions 2 and 4 (not adjacent)
- H-G: positions 3 and 4 (adjacent)
- G-A: positions 4 and 5 (adjacent)
A-D, F-G are not adjacent pairs. But F-G has one person between while A-D has two. Actually rechecking: B-C, H-G, G-A are adjacent (direct neighbors).
Question 5 (Hard): If all persons are made to sit in alphabetical order from left to right, how many will remain in their original positions?
Solution: Original: E(1), F(2), H(3), G(4), A(5), B(6), C(7), D(8) Alphabetical: A(1), B(2), C(3), D(4), E(5), F(6), G(7), H(8)
Comparing positions - none match.
Set 2: Circular Seating Arrangement
Directions (Q.6-10): Eight friends P, Q, R, S, T, U, V, W sit around a circular table facing center.
Given:
- P sits third to the right of Q
- R sits second to the left of Q
- S is an immediate neighbor of both P and R
- T sits opposite to Q
- U sits second to the right of T
- V is not an immediate neighbor of Q
- W sits between U and V
Question 6 (Medium): Who sits immediate left of P?
Solution: Setting Q at position 1:
- P is 3rd to right → P at position 4
- R is 2nd to left → R at position 7
- T is opposite Q → T at position 5
- S is neighbor of both P and R → S at position 3 or 6
After complete arrangement: R sits immediate left of P.
Question 7 (Medium): Who sits opposite to S?
Solution: With S at position 3, opposite is position 7. But R is at 7. Rearranging: If S is at position 6, opposite is position 2.
Question 8 (Medium): How many persons sit between U and Q when counted clockwise?
Solution: U is 2nd to right of T. If T=5, U=7. Clockwise from U(7) to Q(1): only position 8 is between.
Question 9 (Hard): Which pair represents the immediate neighbors of W?
Solution: Given W sits between U and V.
Question 10 (Hard): If P and T interchange positions, and S and U interchange positions, who will be the new immediate neighbors of Q?
Solution: After swaps, analyzing new positions:
Set 3: Floor-Based Puzzle
Directions (Q.11-15): Seven persons A, B, C, D, E, F, G live on floors 1-7.
Given:
- A lives on floor 4
- Only two persons live between A and B
- C lives immediately above D
- E lives on an odd-numbered floor below floor 4
- F lives on a floor above G but below A
- G does not live on floor 1
Question 11 (Easy): Who lives on floor 7?
Solution:
- A = floor 4
- Two persons between A and B → B = floor 1 or 7
- Testing B = 1 leads to contradiction with G constraint
- Therefore B = 7
Final arrangement:
- 7: B, 6: C, 5: D, 4: A, 3: F, 2: G, 1: E
Question 12 (Easy): On which floor does F live?
Solution: From arrangement, F is on floor 3.
Question 13 (Medium): How many persons live between C and G?
Solution: C = floor 6, G = floor 2 Floors between: 3, 4, 5 → F, A, D
Question 14 (Medium): Four of the following five are alike. Which does not belong? a) A-C b) F-D c) G-B d) E-C e) F-B
Solution: Gaps: A-C(1), F-D(1), G-B(4), E-C(4), F-B(3)
Question 15 (Hard): If C moves to floor 3 maintaining relative order, who lives on floor 5?
Solution: Original order: E < G < F < A < D < C < B With C at 3: E(1), G(2), C(3), F(4), A(5), D(6), B(7)
Set 4: Comparison Puzzle

Given:
- T scored more marks than only P
- Q scored less marks than only one person
- R is not the lowest scorer
- S did not score the highest marks
Question 16 (Easy): Who scored the highest marks?
Solution:
- "T more than only P" → P is lowest, T is second lowest: P < T
- "Q less than only one" → Q is second highest
- R not lowest (satisfied), S not highest
Order: P < T < S < Q < R
Question 17 (Easy): Who scored the second lowest marks?
Solution: From order P < T < S < Q < R, second lowest is T.
Question 18 (Medium): How many persons scored more marks than S?
Solution: More than S: Q and R → 2 persons.
Question 19 (Medium): If R scored 95 and P scored 65, with equal differences between consecutive ranks, what is Q's score?
Solution: 4 intervals between 5 people. Difference = (95 - 65) / 4 = 7.5 Q = 95 - 7.5 = 87.5
Question 20 (Hard): If U scores between Q and S, how many students score less than U?
Solution: New order: P < T < S < U < Q < R Less than U: P, T, S → 3 students.

Set 8: Advanced Seating with Multiple Attributes
Directions (Q.36-40): Eight people P, Q, R, S, T, U, V, W sit around a square table (2 per side) facing center.
Given:
- P sits at the corner and likes Red
- Q sits second to the right of P and likes Blue
- R sits immediate left of Q and likes Green
- S sits opposite to P and likes Yellow
- T sits between P and S and likes White
- U sits immediate right of S and likes Black
- V likes Orange and sits between Q and S
- W likes Pink and sits at a corner
Question 36 (Medium): Who sits immediate left of T?
Solution: Mapping the square table (positions 1-8, corners at 1,3,5,7):
- P at corner, say position 1 (Red)
- Q 2nd to right of P: position 4 (Blue)
- R immediate left of Q: position 3 (Green)
- S opposite P: position 5 (Yellow)
- T between P and S: position 2 or... checking
- U immediate right of S: position 6 (Black)
- V between Q and S: position 5 is S, so V at position...
After complete mapping: Positions: 1-P, 2-T, 3-R, 4-Q, 5-S, 6-U, 7-W, 8-V
Immediate left of T(2) is P(1) when facing center? Actually depends on direction.
Question 37 (Medium): Who likes Orange?
Solution: Given V likes Orange.
Question 38 (Medium): Who sits opposite to Q?
Solution: Q is at position 4, opposite is position 8. Position 8 has V.
Question 39 (Hard): Four of the following five are alike. Which does not belong? a) P-T b) Q-R c) S-U d) V-W e) T-R
Solution: Checking if pairs are adjacent:
- P-T: positions 1-2, adjacent
- Q-R: positions 4-3, adjacent
- S-U: positions 5-6, adjacent
- V-W: positions 8-7, adjacent
- T-R: positions 2-3, adjacent
All adjacent. Check colors: Red-White, Blue-Green, Yellow-Black, Orange-Pink, White-Green.
Checking corner-mid relationships: P(corner)-T(mid), Q(mid)-R(corner), S(corner)-U(mid), V(mid)-W(corner), T(mid)-R(corner)
All are corner-mid pairs except need to recheck positions.
Actually: P(1-corner), T(2-mid), R(3-corner), Q(4-mid), S(5-corner), U(6-mid), W(7-corner), V(8-mid)
P-T: corner-mid Q-R: mid-corner S-U: corner-mid V-W: mid-corner T-R: mid-corner
All seem similar. Check: All except one... perhaps color combination.
Question 40 (Hard): If everyone shifts one position clockwise, who will sit opposite to the person who likes Yellow?
Solution: Yellow = S at position 5. After clockwise shift: S moves to position 6 (where U was). Opposite of position 6 is position 2. Position 2 had T originally, T moves to position 3. The person now at position 2 is the one from position 1: P.

- Create possibility sets for uncertain positions
- Cross out eliminated options as you deduce
- Keep track of "not" conditions carefully
4. Practice Time Management
- Easy puzzles: 3-4 minutes
- Medium puzzles: 5-7 minutes
- Hard puzzles: 8-10 minutes
- Skip if stuck after 3 minutes, return later
5. Master Different Puzzle Types
- Practice each type separately first
- Then attempt mixed puzzle sets
- Focus on weak areas through targeted practice
6. Develop Systematic Approach
- Read all conditions before starting

- Watch for common errors (left/right confusion)
- Ensure facing directions are correct
Frequently Asked Questions (FAQ)
Q1: How do I improve my puzzle-solving speed?
A: Practice is key. Start with 2-3 puzzles daily. Time yourself and aim to reduce solving time by 10% each week. Focus on quick diagram-making and immediate information extraction.
Q2: Should I attempt all puzzles in an exam?
A: Prioritize easier puzzles first. In most exams, you can attempt 70-80% of puzzles if you manage time well. Don't spend more than 3-4 minutes on a single puzzle initially.
Q3: What if I get stuck on a puzzle?
A: Mark it and move on. Sometimes solving other questions in the set provides clues. Return to it after attempting other questions.
Q4: How important is diagram-making in online exams?
A: Very important. Use the rough sheet provided. Develop a quick notation system. Some online platforms provide digital scratchpads—practice using them.
Q5: Are there any shortcuts for circular arrangements?
A: Yes! Remember:
- Opposite positions in 8-person circle = difference of 4
- Opposite positions in 6-person circle = difference of 3
- "Immediate" always means adjacent (difference of 1)
- Use a standard starting position (like Q at top) consistently
