Square/Rectangular Table: Corners and Middles
Square/Rectangular Table problems involve arranging people around a rectangular or square table, with distinct positions at corners and middle of sides. All persons face the center, so left/right rules follow standard circular seating logic. These problems test spatial reasoning with irregular positioning.

Introduction to Square/Rectangular Table: Corners and Middles
Square/Rectangular Table problems involve arranging people around a rectangular or square table, with distinct positions at corners and middle of sides. All persons face the center, so left/right rules follow standard circular seating logic. These problems test spatial reasoning with irregular positioning.
Prerequisites
How to Solve Square/Rectangular Table: Corners and Middles Problems
Step 1: Identify total persons (typically 8: 4 corners + 4 sides)
Step 2: Label positions in clockwise order: C1, M1, C2, M2, C3, M3, C4, M4
Step 3: Corners are at even or odd positions depending on labeling
Step 4: Apply facing center rules (left = clockwise, right = anticlockwise)
Step 5: Use neighbor and distance constraints to place persons
Step 6: Count middle-seated persons between two given persons
Step 7: Answer questions about positions or counts
Example Problem
Example: 8 persons sit around a square table facing center (4 corners, 4 sides). How many middle-seated persons between X and Y clockwise? Solution: Step 1: Label positions clockwise: C1, M1, C2, M2, C3, M3, C4, M4 Step 2: Locate X and Y in the order Step 3: Count middle positions (M1, M2, M3, M4) encountered while moving clockwise from X to Y (excluding endpoints) Step 4: The count is the answer Answer: Number of middle-seated persons between them
Pro Tips & Tricks
- Standard labeling: positions 1-8 clockwise with corners at 1,3,5,7 (or 2,4,6,8)
- Middle positions are between corners (positions 2,4,6,8)
- Opposite positions are 4 steps away (e.g., position 1 opposite position 5)
- Corners are diagonally opposite to opposite corners
- Persons at corners are not adjacent to each other (separated by a side person)
- For 'between' counting, count only middle positions (sides), not corners
