Prerequisites
How to Solve Circular Mixed Facing Problems
Step 1: Draw circle with numbered positions clockwise
Step 2: Mark facing direction of each person when known (↺ for center, ↻ for outward)
Step 3: For each clue, identify the speaker's facing direction first
Step 4: Translate clue: If faces center → right=clockwise, left=anti-clockwise; If faces outward → right=anti-clockwise, left=clockwise
Step 5: Place definite positions and directions
Step 6: Use relative clues to deduce positions
Step 7: Fill remaining positions and verify all conditions
Example Problem
Example: Eight persons sit around a circle. Some face center, some outward. A faces center and sits third to right of B who faces outward. C sits second to left of A and faces same direction as B. Who sits second to right of C? Solution: Step 1: Positions 1-8 clockwise Step 2: A faces center → A's right=clockwise Step 3: B faces outward → B's right=anti-clockwise Step 4: A third to right of B: from B, move 3 steps clockwise (since A's right is clockwise, but careful: clue is from B's perspective? Actually 'A sits third to right of B' uses B's perspective. B faces outward, so B's right=anti-clockwise. So A is 3 steps anti-clockwise from B) Step 5: Place accordingly Step 6: Continue with C's placement Step 7: Find second to right of C based on C's facing direction Answer: Person determined by final arrangement
