3. C does not stay as PG and studies Philosophy. A studies Accountancy.
4. The students studying Zoology and Botany do not stay in PG.
5. F studies Botany and D studies Psychology. F and D stay in hostel. E stays in PG and B stays at home.
Which of the following combinations of subject and place of stay is correct?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Philosophy-Home
The clues are used first for the subjects, then for the places of stay; each step uses a clue on what is already fixed.
Subjects:
Clue 3: C studies Philosophy and A studies Accountancy
Clue 5: F studies Botany and D studies Psychology
Economics and Zoology are left for B and E. E stays in PG, and the Zoology student does not stay in PG (clue 4), so E studies Economics and B studies Zoology
Places of stay:
Clue 5: F and D stay in the hostel, E in PG and B at home
The two hostel places are now taken, and C does not stay in PG (clue 3), so C stays at home
The second PG place is left for A
The combinations in the options:
Option (1) Economics-Hostel — Incorrect. Economics is E’s subject, and E stays in PG.
Option (2) Botany-PG — Incorrect. Botany is F’s subject, and F stays in the hostel.
Option (3) Philosophy-Home — Correct. Philosophy is C’s subject, and C stays at home.
Option (4) Psychology-PG — Incorrect. Psychology is D’s subject, and D stays in the hostel.
