Question 1
Six persons have distinct preferences across Brand, Sport, and Vehicle. Using the clues, determine the complete mapping and answer:
- Priya does not prefer Epsilon or Hockey.
- The one who prefers Beta drives Ship.
- Rhea plays Chess, and the one who drives Car prefers Gamma.
- Neither Qadir nor Vihaan prefers Delta.
- The Football player does not drive Scooter.
- If someone prefers Alpha, then they do not play Table Tennis.
Question: Who drives the Ship?
CAT/GMAT-Style Multi-Parameter Table
Create a 6x4 table (Person x Brand x Sport x Vehicle).
Apply constraints in layers: negative exclusions first, then direct mappings, then conditional implications.
- Priya does not prefer Epsilon or Hockey.
- The one who prefers Beta drives Ship.
- Rhea plays Chess, and the one who drives Car prefers Gamma.
- Neither Qadir nor Vihaan prefers Delta.
- The Football player does not drive Scooter.
- If someone prefers Alpha, then they do not play Table Tennis.
Continue elimination until each row has a unique triplet.
Verified final mapping:
Person | Brand | Sport | Vehicle
--- | --- | --- | ---
Priya | Beta | Football | Train
Tara | Epsilon | Table Tennis | Car
Rhea | Delta | Hockey | Scooter
Qadir | Alpha | Athletics | Ship
Vihaan | Kappa | Chess | Cycle
Sahil | Gamma | Cricket | Metro
Efficiency tip: Track constraints per attribute as sets; propagate implications ('If A then not B').
Verification:
- Each attribute used exactly once across persons.
- All conditional and negative clues hold.
- No contradictions; unique solution obtained.
