Seven persons P, Q, R, S, T, V and X belonging to different cities viz. Delhi,…

This is a linear person-to-city-to-specialization matching puzzle: each clue either states a link directly or rules one out. Fix every directly-stated link first, then use elimination on whichever people and specializations remain, one attribute at a time, until the table closes completely.

1. R is stated directly to be from Mumbai, specializing in Marketing.

2. V is stated directly to be from Trivandrum, specializing in Physics.

3. X is stated directly to be from Bangalore, specializing in Information Technology.

4. S is stated directly to be from Chennai.

5. The three remaining cities, Delhi, Calcutta, and Hyderabad, must go to P, Q, and T in some order.

6. P specializes in Literature and is not from Delhi. Since the Calcutta person specializes in Computers (not Literature), P cannot be from Calcutta either, so P must be from Hyderabad.

7. That leaves Delhi and Calcutta to be shared between Q and T.

8. Of the seven specializations, Marketing, Physics, Information Technology, and Literature are already assigned to R, V, X, and P. The three left, Economics, Computers, and Textile Engineering, belong to Q, S, and T.

9. Q does not specialize in Textile Engineering or Economics, so Computers is the only specialization left for Q.

10. The Calcutta person specializes in Computers, and Q is the Computers specialist, so Q must be the one from Calcutta.

11. With Q taking Calcutta, Delhi is the only city left for T.

Cross-check against every clue with the completed table below: R-Mumbai-Marketing, V-Trivandrum-Physics, X-Bangalore-Information Technology, S-Chennai, P-Hyderabad-Literature (not Delhi, as required), Q-Calcutta-Computers (matching the Calcutta clue), and T-Delhi all hold together without contradiction. (The clues do not fix whether S or T takes Economics versus Textile Engineering specifically, but that split does not affect where T lives.)

So T belongs to Delhi.
