In a certain code language, 'P $ Q' means 'Q is the spouse of P', 'P ¥ Q' means 'Q is the mother of P', 'P f Q' means 'P is the daughter of Q', 'P * Q' means 'P is the sister of Q'. If 'T f N * C ¥ K $ R', then what is the relationship of R with T?

Appeared in: NHM UP Staff Nurse-2023 shift 1st

Explanation

The expression 'T f N * C ¥ K $ R' is decoded sequentially to build a family tree.
'T f N' establishes T as the daughter of N.
'N * C' confirms N is female (sister), making her T's mother.
'C ¥ K' establishes K as the mother of N and C, making K T's maternal grandmother.
'K $ R' establishes R as the spouse (husband) of K.
As the husband of T's maternal grandmother, R is T's maternal grandfather.

Option B: This is the role of K. The expression 'C ¥ K' means K is the mother of C (and N), making K the maternal grandmother. R is the spouse of K.
Option C: This describes the relationship of T to R, not R to T. The question asks how R is related to T.
Option D: This role belongs to a different generation. C is N's sibling, making C the maternal uncle (if male) or maternal aunt (if female) of T. R is from the grandparent generation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Coded Blood Relations as background academic context rather than a clinical decision trigger.
While not a clinical question, this type of logical reasoning is a foundational skill for nurses. It is essential for interpreting complex patient information, understanding family health histories, and making sound clinical judgments.
This skill helps in piecing together different data points (like symptoms, lab results, and patient statements) to form a coherent clinical picture, similar to how the coded relationships are pieced together.
What if the expression was 'T f N * C ¥ K f R'? In this case, 'K f R' would mean K is the daughter of R. Since K is T's grandmother, R would be T's maternal great-grandparent (either great-grandfather or great-grandmother).

How to Approach the Question

First, carefully list and understand the meaning of each symbol ($, ¥, f, *). Create a simple key for reference.
Break down the given complex expression ('T f N * C ¥ K $ R') into smaller, sequential parts.
Start from the first relationship (T f N) and build the family tree or map out the relationships step-by-step.
Pay close attention to the direction of the relationship defined by the code (e.g., 'P f Q' means P is the daughter of Q, not the other way around).
Determine the gender of individuals whenever possible from the relationship terms (e.g., 'sister' implies female, 'mother' implies female, 'spouse of a female' implies male).
Once the full family tree is mapped out, identify the final relationship requested by the question (R's relationship to T).
