Kiran is Sister of Raj. Raj is Son of Suresh and Vinita is Mother of Suresh then what is relation between Vinita and Kiran?

Appeared in: KGMU 2023

Explanation

The question establishes that Kiran and Raj are siblings.
It then states that Raj's father is Suresh, which makes Suresh the father of Kiran as well.
The final link is that Vinita is the mother of Suresh.
Therefore, Vinita is the mother of Kiran's father, which defines the relationship of a paternal grandmother.

Option A: Kiran is the granddaughter of Vinita, not her daughter. This option confuses the generational direction.
Option B: Vinita is the mother of Suresh, not Kiran. This option incorrectly assigns the mother-child relationship to the wrong generation.
Option D: Kiran and Vinita are separated by two generations (grandmother-granddaughter). A sister relationship exists within the same generation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Blood Relations as background academic context rather than a clinical decision trigger.
Logical reasoning questions, such as those involving blood relations, are a standard part of nursing entrance exams to evaluate a candidate's critical thinking and problem-solving abilities.
These skills are vital for nurses to quickly analyze complex patient information, understand family dynamics when taking a patient history, and make accurate clinical judgments.
What if the question asked for the relationship between Raj and Vinita? The relationship would be the same. Since Raj and Kiran are siblings, Vinita is also Raj's paternal grandmother.

How to Approach the Question

First, deconstruct the problem into individual relationship statements (e.g., Kiran is Raj's sister).
Identify the two people whose relationship needs to be determined (Vinita and Kiran).
Trace the connections link by link: Kiran's brother is Raj -> Raj's father is Suresh -> Suresh's mother is Vinita.
Visualize or sketch a simple family tree to map the generations. Vinita is Generation 1, Suresh is Generation 2, and Kiran is Generation 3.
Combine the links to define the final relationship: Kiran's father's mother is her paternal grandmother.
Review the options and eliminate those that are inconsistent with the generational structure (e.g., Daughter, Sister).
