UPSC CSE Prelims 2016

There are five persons in a group — P, Q, R, S and T. The group has one doctor, one lawyer and one artist. P and S are unmarried students. T is a man married to one of the group members. Q is the brother of P and is neither doctor nor artist. R is not doctor.

Who is the artist?

EXPLANATION

Correct Option (3)

Based on the given information, the roles can be deduced as follows:

P and S are identified as unmarried students. This implies they do not hold the professional roles of doctor, lawyer, or artist.
Q is stated to be neither a doctor nor an artist. Given that P and S are students, and there are only three professional roles (doctor, lawyer, artist), Q must therefore be the lawyer.
R is stated not to be a doctor. With Q confirmed as the lawyer, and P and S as students, the only remaining professional role for R is the artist.
Consequently, T, being the only remaining person with a professional role, must be the doctor.

Therefore, R is the artist.

Incorrect Options

P: P is an unmarried student. Students are not identified as holding the professional roles of doctor, lawyer, or artist within the group.
Q: Q is explicitly stated to be neither a doctor nor an artist. Through deduction, Q is identified as the lawyer.
T: T is the remaining individual after P, Q, R, and S have been assigned roles or status. T is identified as the doctor.
