Linear Single Row North Facing
Linear Single Row North Facing problems involve arranging persons in a straight row where all individuals face North. When facing North, a person's right hand points East (viewer's right) and left hand points West (viewer's left). These problems test your ability to interpret directional clues in a linear context.

Introduction to Linear Single Row North Facing
Linear Single Row North Facing problems involve arranging persons in a straight row where all individuals face North. When facing North, a person's right hand points East (viewer's right) and left hand points West (viewer's left). These problems test your ability to interpret directional clues in a linear context.
Prerequisites
How to Solve Linear Single Row North Facing Problems
Step 1: Draw a horizontal line representing the row with positions numbered 1 to n (usually left to right from viewer's perspective)
Step 2: Note that all persons face North, so their right is the viewer's right, left is viewer's left
Step 3: Place definite positions first (e.g., 'A sits at extreme left end' → position 1)
Step 4: Apply relative position clues ('A sits second to the right of B' → if B is at position x, A is at x+2)
Step 5: Use immediate neighbor clues ('A sits immediately to the left of B' → A at x, B at x+1)
Step 6: Fill remaining positions using process of elimination
Step 7: Verify all conditions are satisfied in your final arrangement
Example Problem
Example: Five persons A, B, C, D, E sit in a row facing North. A sits at the left extreme end. B sits second to the right of A. C sits immediately to the left of B. D is not at any extreme end. Who sits at the right extreme end? Solution: Step 1: Draw 5 positions: 1,2,3,4,5 (left to right) Step 2: A at left extreme → position 1 Step 3: B sits second to right of A (position 1) → position 3 Step 4: C sits immediately left of B (position 3) → position 2 Step 5: Positions filled: 1=A, 2=C, 3=B, 4=_, 5=_ Step 6: D not at extremes → D at position 4 Step 7: Remaining E at position 5 (right extreme) Answer: E
Pro Tips & Tricks
- For North-facing: left = viewer's left, right = viewer's right
- Extreme left = position 1, extreme right = last position
- 'Second to the right' means move 2 positions to the right
- 'Immediately to the left' means adjacent position on left side
- Draw empty slots (_) for unknown positions
- Use process of elimination for remaining persons
