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 lawyer?

EXPLANATION

Correct Option (B)

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

P and S are unmarried students. This indicates they do not hold any of the professional roles (doctor, lawyer, artist) within the group.
Q is explicitly stated to be neither a doctor nor an artist. Given that P and S are students and thus not professionals, Q must occupy the remaining professional role, which is the lawyer.
Therefore, Q is the lawyer.

Incorrect Options:

Option (A) P: P is an unmarried student and therefore does not hold a professional role.
Option (C) R: R is stated not to be a doctor. Since Q is identified as the lawyer, and P and S are students, R must be the artist to fulfill the remaining professional role.
Option (D) S: S is an unmarried student and therefore does not hold a professional role.
By elimination, T, who is married, would then be the doctor.
