A, B, C and D are students. They are studying in four different cities, namely in P, Q, R and S (not necessarily in that order). They are studying in Science college, Arts college, Commerce college and Engineering college (not necessarily in that order), which are situated in four different states, such as Gujarat, Rajasthan, Assam and Kerala (not necessarily in that order). Further, it is given that

  1. D is studying in Assam.
  2. Arts College is located in city S which is in Rajasthan.
  3. A is studying in Commerce college.
  4. B is studying in city Q.
  5. Science college is located in Kerala.

Which one of the following statements is correct regarding Engineering College?

EXPLANATION

Correct Option (D)

The relationships between students, cities, colleges, and states can be established through a systematic deduction process based on the given clues:

  • Clue (1) states that D is studying in Assam.
  • Clue (2) indicates that Arts College is located in City S, which is in Rajasthan.
  • Clue (3) specifies that A is studying in Commerce College.
  • Clue (4) states that B is studying in City Q.
  • Clue (5) identifies Science College as being located in Kerala.

By combining these statements:

  • Given D is in Assam, A is in Commerce College, and B is in City Q, C must be the student associated with Arts College, City S, Rajasthan. Thus, C is studying in Arts College, located in City S, Rajasthan.
  • Since Science College is in Kerala, and B is in City Q, B must be the student studying in Science College, located in City Q, Kerala.
  • With A in Commerce College, B in Science College, and C in Arts College, Engineering College is the only remaining college. Therefore, D must be studying in Engineering College.
  • The remaining state for A (Commerce College) is Gujarat.
  • The remaining state for D (Engineering College) is Assam, as per clue (1).

The complete mapping derived is:

  • A: Commerce College, Gujarat (City P or R)
  • B: Science College, City Q, Kerala
  • C: Arts College, City S, Rajasthan
  • D: Engineering College, Assam (City P or R)

Based on this deduction, D is studying in Engineering College.

Incorrect Options:

  • Option (A) C is studying there: Incorrect. C is studying in Arts College.

  • Option (B) B is studying there: Incorrect. B is studying in Science College.

  • Option (C) It is located in Gujarat: Incorrect. Engineering College is located in Assam.
