Question 1
Consider the following five database-like records with unique fields (ID, Name, City, Score). Using the clues, determine relationships and answer:
- The record with ID 200 has a higher score than the record from Chennai.
- Tara's score is not the lowest.
- The person from Delhi has an ID greater than 668.
Question: Which city corresponds to the highest score?
Relational Reasoning (DB-style)
Think in terms of unique-key constraints across fields (ID, Name, City, Score).
ID | Name | City | Score
--- | --- | --- | ---
200 | Qadir | Bengaluru | 97
718 | Mira | Chennai | 74
897 | Tara | Hyderabad | 91
436 | Priya | Delhi | 70
668 | Rhea | Mumbai | 96
Use comparative score clues and ID inequalities to identify maxima/minima.
Verification:
- The record with ID 200 has a higher score than the record from Chennai.
- Tara's score is not the lowest.
- The person from Delhi has an ID greater than 668.
