Pointing to a woman, Raj said, “She is the daughter of the only son of my father.” Who is she to Raj?

Appeared in: HPSSC - 2015

Explanation

Option A: A sister would be the daughter of Raj's father, not the daughter of Raj himself.
Option B: A niece is the daughter of one's sibling. The statement specifies Raj is the 'only son', meaning he has no brother whose daughter she could be.
Option D: A cousin is the child of one's aunt or uncle. The relationship described is much more direct (father-daughter).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Blood Relations and Logical Deduction as background academic context rather than a clinical decision trigger.
Logical reasoning questions are a standard component of the General Intelligence section in nursing and other competitive examinations.
These questions assess a candidate's ability to analyze information, deconstruct complex statements, and deduce logical conclusions, which are essential skills for critical thinking in a clinical setting.
Mastering these puzzles involves identifying the key relationships and working backward from the speaker's perspective.

How to Approach the Question

First, identify the speaker (Raj) and the person being described (the woman).
Break the statement into smaller, logical parts: 'She is the daughter of' + 'the only son of' + 'my father'.
Start solving from the end of the statement and move backward. 'My father' refers to Raj's father.
Next, analyze 'the only son of my father'. Since Raj is the speaker, this refers to Raj himself.
Finally, substitute this back into the first part: 'She is the daughter of (Raj)'.
This directly establishes the relationship as daughter. Compare this conclusion with the given options to find the correct answer.
