Correct Answer Physics

People - Kamal, Nalini, Namrata, Sheela, Shakti, Arun and Sukanya.

Three different subjects - Mathematics, Science and Physics.

Three different schools - P, Q and R.

1. Namrata studies Mathematics in school P which has only one more student named Shakti.

2. Kamal does not study in school R but he is a student of mathematics.

3. Sheila studies physics in school R.

4. Nalini is also a student of school R.

5. Arun and Sukanya do not study in school R.

6. Nalini and Shakti study science.

7. Shakti and Sukanya study the same subject.

As Shakti studies science, so Sukanya also studies science.

Three people studies science, two people studies mathematics and one people studies physics.

Less than two and no more than three people study the same subject.

Less than two and not more than three people study in the same school.

From the above two statement, it is clear that one more people studies Physics.

As Arun is the only person whose subject column is vacant, so it is clear that he studies physics.

Hence, ‘Physics’ is the correct answer.
