Students Anu, Binu, Chinki and Debu study one subject each from among Geography, History, English or Physics whose books are placed in a sequence on the bookshelf. Chinki studies English book. History book is adjacent to the Physics book. Anu does not study the book adjacent to the book studied by Chinki. English book is the only book in between the History and Geography books. What subject book does Anu study?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Physics
Fix the order of the books first, then use the clue about Anu.
English is the only book between History and Geography: the three stand as History, English, Geography (or the other way round).
History is next to Physics: Physics goes at the History end, giving Physics, History, English, Geography (or Geography, English, History, Physics).
Chinki has English, and the books next to English are History and Geography. Anu does not have a book next to Chinki’s, so Anu has neither of them and not English either: Anu has Physics.
