Question

Difficulty: EasyBlood Relations

Rohit introduces Priya at a social event, stating, 'She is the mother of my father's only son.' Assuming Rohit is a male and has no brothers or sisters, what is Priya's relationship to Rohit?

Answer: Mother / mother

Answer

Priya is Rohit's mother.
The phrase 'my father's only son' uniquely identifies Rohit himself because Rohit is a male without siblings. Replacing this phrase into the original statement yields 'She is the mother of Rohit', establishing Priya as Rohit's mother.

Step-by-Step Solution

1
Analyze the phrase 'my father's only son'.
Since Rohit is male and has no siblings, his father's only son must be Rohit himself.
An only son of a father with no other children refers directly to the speaker.
2
Substitute this result back into the full statement.
'Priya is the mother of Rohit.'
Replacing 'my father's only son' with 'Rohit' simplifies the relation.
3
Determine the final kinship relation of Priya to Rohit.
Priya is the mother of Rohit.
Direct relationship derived from the decoded statement.
