B and E are good in Dramatics and Computer Science. A and B are good in Computer Science and Physics. A, D and C are good in Physics and History. C and A are good in Physics and Mathematics. D and E are good in History and Dramatics. Who is good in Computer Science, History and Dramatics?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → E
List the people good in each of the three subjects asked, then pick the one name that is on all three lists.
Computer Science: B and E (first sentence), A and B (second sentence), so A, B and E
History: A, D and C (third sentence), D and E (fifth sentence), so A, C, D and E
Dramatics: B and E (first sentence), D and E (fifth sentence), so B, D and E
Only E is on all three lists. A is not good in Dramatics, B is not good in History, and C is good in neither Computer Science nor Dramatics.
