A is the sister of B. C is the father of B's mother D. E is the brother of C. How is A related to E?

Appeared in: Bihar NHM CHO-2025

Explanation

Option A: This is incorrect because the first statement explicitly identifies A as a 'sister,' which means A is female, not a male 'son'.
Option B: This describes the relationship of D (A's mother) to E. D is the daughter of C, who is E's brother. A is one generation further down the family line.
Option D: This is incorrect as the statements describe blood relationships (sister, father, mother, brother), not a marital relationship involving E or his brother.

Visual 1: Flowchart - A family tree diagram illustrating the relationships. It would show E and C as brothers. A branch from C would lead to his daughter D. A branch from D would lead to her daughter A, visually confirming A is E's brother's daughter's daughter.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Blood Relations as background academic context rather than a clinical decision trigger.
While not a clinical question, this type of problem assesses logical and deductive reasoning, a foundational skill for nurses.
Nurses use deductive reasoning to analyze patient symptoms, medical history, and lab results to identify potential health problems and formulate care plans.
What if? - If the question asked for E's relationship to A, the answer would be 'Maternal Great-Uncle'.

How to Approach the Question

First, carefully read each statement and identify the gender of each person if specified (e.g., 'A is the sister' means A is female).
Break down the relationships one by one: A and B are siblings; D is their mother; C is their maternal grandfather.
Establish the final link: E is the brother of the grandfather (C), making E the great-uncle.
To avoid confusion, draw a simple family tree or diagram to visualize the connections.
Finally, trace the relationship path from the perspective of the person asked (E) to the other person (A), following the connections on your diagram to select the correct option.
