Introduction
To determine the subject taught by teacher C, we need to analyze the clues provided and arrange the teachers with their respective subjects accordingly.
Clues Breakdown
- The physics book's rack number is thrice that of the biology book.
- Teacher E's book is just above the biology book.
- Teacher H teaches English and is 3 racks above teacher B's book.
- The Hindi and chemistry books are in consecutive racks.
- The Hindi book's rack number is twice that of teacher A's book.
- The mathematics book is either on the top or the lowest rack.
- Teacher D's book is 3 books below teacher G's book.
- The geography book is 2 books below the chemistry book.
- Teacher C's book is in rack 7.
- Teacher B does not teach biology or physics.
Rack Arrangement
1. Since C's book is in rack 7, and H's book is above B's book, we can start positioning:
- H must be in rack 6 or 5, and B must be below H.
2. From the clues, we deduce:
- If B is in rack 4, then H can be in rack 7 (not possible since C is there), so B must be in rack 5 or lower.
3. Considering the other clues about subjects:
- Since B cannot teach biology or physics, the only options left for B are Hindi, Chemistry, History, or Geography.
- Hence, when we place the subjects, C must be teaching History as it fits the arrangement while adhering to other conditions.
Final Conclusion
Based on the arrangement and the process of elimination, the subject taught by teacher C is:
Answer: History
