Transitive Relations
Transitive Relations problems focus specifically on applying the transitive property of inequalities. Given a chain of relationships, you must determine which non-adjacent pairs have a definite relationship based on transitivity. These problems test your understanding of when and how transitivity applies.

Prerequisites
How to Solve Transitive Relations Problems
Step 1: Decode the given chain of relationships
Step 2: Identify pairs of variables that are connected through intermediate variables
Step 3: For each pair, examine the direction of all relationships along the path
Step 4: If all signs along the path point in the same direction (all >, all <, all ≥, all ≤, or a mix with =), transitivity applies
Step 5: If the path contains a reversal (> followed by < or vice versa), transitivity does NOT apply
Step 6: Apply transitivity to derive the relationship between the outer variables
Step 7: Compare derived relationships with the given conclusions
Step 8: Determine which conclusions follow from transitivity
Example Problem
Example: If @ = >, # = <, decode: A @ B @ C # D. Which transitive conclusions follow? Solution: Step 1: Decode: A > B > C < D Step 2: A to C path: A > B > C → all '>' signs → A > C follows Step 3: A to D path: A > B > C < D → contains reversal ( > then < ) → no transitive relation Step 4: B to D path: B > C < D → contains reversal → no transitive relation Step 5: C to D: C < D directly given Answer: Only A > C follows by transitivity
Pro Tips & Tricks
- Transitivity works when all inequalities point the same way
- The '=' symbol can be included in any transitive chain without breaking direction
- A path with a single reversal invalidates transitivity for that entire path
- Shorter paths are more likely to satisfy transitivity conditions
- Always check the longest path when evaluating far-apart variables
- Remember: 'A > B' and 'B = C' gives 'A > C'
