Study the following information carefully and answer the given question:
(i) B and E are good in Dramatics and Computer Science;
(ii) A and B are good in Computer Science and Physics;
(iii) A, D and C are good in Physics and History;
(iv) C and A are good in Physics and Mathematics;
(v) D and E are good in History and Dramatics;
Who is good in Physics, History and Dramatics?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → D
Step 1: List the information clearly
- B and E → Dramatics & Computer Science
- B: Dramatics, CS
- E: Dramatics, CS
- A and B → CS & Physics
- A: CS, Physics
- B: CS, Physics
- A, D, C → Physics & History
- A: Physics, History
- D: Physics, History
- C: Physics, History
- C and A → Physics & Mathematics
- C: Physics, Mathematics
- A: Physics, Mathematics
- D and E → History & Dramatics
- D: History, Dramatics
- E: History, Dramatics
Step 2: Find intersection: Physics, History, Dramatics
- Physics: A, B, C, D
- History: A, C, D, E
- Dramatics: B, D, E
Who is in all three lists?
- Physics ∩ History ∩ Dramatics = D
