Who is the spouse of R ?
- (a) P
- (b) T ✓ UPSC's answer
- (c) Q
- (d) S
Why the answer is (b)
• P and S are unmarried students, so they cannot be the spouse of R.
• T is a man married to one of the group members, meaning T is the spouse of a female member.
• Q is the brother of P, making Q male; since T is male, Q cannot be T's spouse, and T cannot be Q's spouse.
• The only remaining female member who is not unmarried is R, so T must be married to R.
• Therefore, T is the spouse of R.
Why the other options are wrong
- (a) P
- P is explicitly stated to be an unmarried student, so P cannot be the spouse of R.
- (c) Q
- Q is the brother of P, making Q male, and T is a man, so Q cannot be the spouse of R in this context where T is the only married male.
- (d) S
- S is explicitly stated to be an unmarried student, so S cannot be the spouse of R.
