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 880 has a higher score than the record from Chennai.
- Mira's score is not the lowest.
- The person from Hyderabad has an ID greater than 211.
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
--- | --- | --- | ---
880 | Ira | Bengaluru | 98
137 | Xavier | Chennai | 79
104 | Mira | Delhi | 88
524 | Rhea | Hyderabad | 83
211 | Diya | Mumbai | 75
Use comparative score clues and ID inequalities to identify maxima/minima.
Verification:
- The record with ID 880 has a higher score than the record from Chennai.
- Mira's score is not the lowest.
- The person from Hyderabad has an ID greater than 211.
