Question 1
Six persons have distinct preferences across Brand, Sport, and Vehicle. Using the clues, determine the complete mapping and answer:
- Zoya does not prefer Epsilon or Chess.
- The one who prefers Delta drives Truck.
- Hina plays Cricket, and the one who drives Train prefers Alpha.
- Neither Tara nor Fatima prefers Eta.
- The Football player does not drive Scooter.
- If someone prefers Iota, then they do not play Tennis.
Question: Who prefers the brand Alpha?
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.
- Zoya does not prefer Epsilon or Chess.
- The one who prefers Delta drives Truck.
- Hina plays Cricket, and the one who drives Train prefers Alpha.
- Neither Tara nor Fatima prefers Eta.
- The Football player does not drive Scooter.
- If someone prefers Iota, then they do not play Tennis.
Continue elimination until each row has a unique triplet.
Verified final mapping:
Person | Brand | Sport | Vehicle
--- | --- | --- | ---
Zoya | Delta | Football | Van
Nihal | Epsilon | Tennis | Train
Hina | Eta | Chess | Scooter
Tara | Iota | Badminton | Truck
Fatima | Gamma | Cricket | Bike
Laksh | Alpha | Athletics | 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.
