Relative Positions (Ambiguity Resolution)
Relative Positions with Ambiguity Resolution problems present positional clues that allow multiple valid arrangements. You must determine which information resolves the ambiguity or identify when a conclusion cannot be uniquely determined. These problems test your ability to recognize insufficient information.

Introduction to Relative Positions (Ambiguity Resolution)
Relative Positions with Ambiguity Resolution problems present positional clues that allow multiple valid arrangements. You must determine which information resolves the ambiguity or identify when a conclusion cannot be uniquely determined. These problems test your ability to recognize insufficient information.
Prerequisites
How to Solve Relative Positions (Ambiguity Resolution) Problems
Step 1: List all given positional clues
Step 2: Draw all possible arrangements that satisfy all clues
Step 3: Count how many valid arrangements exist
Step 4: If only one arrangement, all relationships are definite
Step 5: If multiple arrangements, identify which relationships are constant across all
Step 6: Relationships that vary are ambiguous ('cannot be determined')
Step 7: Additional clues may resolve ambiguity
Step 8: Answer based on definite relationships only
Example Problem
Example: A sits to the left of B. C sits to the right of B. Who is at the extreme left? Solution: Step 1: A left of B, C right of B → order: A, B, C (but could have others between) Step 2: Possible arrangements: A _ B _ C (with spaces for others) Step 3: A could be at left end or not, depending on others Step 4: Without total persons, cannot determine who is at extreme left Answer: Cannot be determined
Pro Tips & Tricks
- If multiple arrangements exist, check which facts are common to all
- The answer is 'Cannot be determined' if the relationship changes across arrangements
- Additional constraints (like 'A is at an end') can resolve ambiguity
- Sometimes the ambiguity is intentional in the question
- Draw all possible cases systematically
- Look for constraints that reduce the number of possibilities
