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 pairs of students have accommodation at hostel and another one at home?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → DC
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 pairs in the options:
Option (1) BC — Incorrect. B and C both stay at home.
Option (2) DC — Correct. D stays in the hostel and C at home.
Option (3) FD — Incorrect. F and D both stay in the hostel.
Option (4) AE — Incorrect. A and E both stay in PG.
