R is a man of Marketing and comes from Mumbai.

The person from Calcutta has specialized in computers.

P who is specialized in literature does not belong to Delhi.

V having specialization in Physics is from Trivandrum.

Information technology is the specialization of X who comes from Bangalore.

Show answer & explanation

Correct answer: C

In a one-clue-per-fact assignment puzzle, every person gets exactly one city and exactly one specialization, and no two people can share either. Solve by first locking in every DIRECT statement (a person named alongside a city or specialization), then use the remaining constraints to ELIMINATE possibilities until only one valid assignment survives for the person(s) asked about.

Applying it to this puzzle:

  1. Direct clues fix four person-city-specialization sets immediately: S -> Chennai; R -> Mumbai with Marketing; V -> Trivandrum with Physics; X -> Bangalore with Information Technology.

  2. "The person from Calcutta has specialized in computers" ties the Computers specialization to whichever of the remaining three persons (P, Q, T) lives in Calcutta; the other two of them get Delhi and Hyderabad.

  3. P holds Literature and is explicitly stated to NOT belong to Delhi. Since the Calcutta resident's specialization is Computers (not Literature), P also cannot be the Calcutta resident. That leaves only Hyderabad for P.

  4. With P fixed to Hyderabad, Delhi and Calcutta remain to be split between Q and T.

  5. Q is explicitly excluded from Textile and Economics. Of the three specializations left unassigned (Economics, Computers, Textile engineering), the only one Q can hold is Computers.

  6. Since the Calcutta resident is the one with Computers, and Q is the only remaining person who can hold Computers, Q must be the Calcutta resident — leaving Delhi for T.

This gives the complete assignment:

Person

City

Specialization

P

Hyderabad

Literature

Q

Calcutta

Computers

R

Mumbai

Marketing

S

Chennai

Economics / Textile engineering

T

Delhi

Textile engineering / Economics

V

Trivandrum

Physics

X

Bangalore

Information Technology

Cross-check against every clue:

  • S is from Chennai - matches the direct statement.

  • Q's specialization is Computers, so it is neither Textile nor Economics - matches the exclusion clue.

  • R is from Mumbai with Marketing - matches.

  • The Calcutta resident (Q) has Computers - matches.

  • P (Literature) is not in Delhi and is placed in Hyderabad - matches.

  • V (Physics) is in Trivandrum - matches.

  • X (Information Technology) is in Bangalore - matches.

(The exact split of Economics and Textile engineering between S and T is not fixed by the given clues, but it does not affect which city each person is in.)

So the person from Hyderabad is P.
