B is the sister of D, who is the father of C. E is the son of D. F is the mother of E. How is B related to F?

Appeared in: DSSSB 12 August 2024

Explanation

The statements establish that D is the father of E and F is the mother of E, which makes them a married couple.
B is explicitly stated to be the sister of D.
Therefore, B is the sister of F's husband.
The relationship of a person to their husband's sister is 'sister-in-law'.

Option A: F is the mother of E and C. B belongs to the same generation as D and F, not the generation above them.
Option C: A mother-in-law is the mother of one's spouse. B is the sister of F's spouse (D), not his mother.
Option D: B is the sister of D, not F. They are related by marriage (in-laws), not by blood.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical deduction and the understanding of kinship terms within a family structure as background academic context rather than a clinical decision trigger.
Logical reasoning questions, including blood relations, are a common component of the non-nursing section of nursing competitive exams.
These questions assess analytical thinking and the ability to deduce relationships from given information, a skill useful in processing complex patient information and family histories.
What if the question asked how F is related to B? The relationship is reciprocal; F would also be B's sister-in-law (the wife of her brother).

How to Approach the Question

First, read the entire problem to understand all the characters and relationships mentioned.
Break down each statement and represent it visually. Use symbols like '+' for male, '-' for female, and a double line for a married couple.
Statement 1: 'B is the sister of D' (B is female, D is male, they are siblings).
Statement 2: 'D is the father of C' and 'E is the son of D' (D has two children, C and E).
Statement 3: 'F is the mother of E' (Since D is the father, F must be D's wife).
Finally, trace the relationship between the two individuals in the question: B and F. B is the sister of F's husband, which defines the relationship as sister-in-law.
