Dilip and Rohit are two brothers. Rohit is the son of Ganesh. Dilip is not older than Rohit. If Dilip is not Rohit’s mother, then who is Rohit’s mother?

Appeared in: AIIMS Bhopal NO - 2018 (Shift-1st)

Explanation

The provided statements establish that Dilip and Rohit are brothers and Ganesh is their father.
The question asks for the identity of the mother, but her name is never mentioned in the text.
Because a key piece of information (the mother's name) is missing, it is impossible to determine the answer from the given context.

Option A: Rohit is the subject of the question and is identified as the son of Ganesh. He cannot be his own mother.
Option B: The name 'Dinesh' is not mentioned anywhere in the problem statement, making it an irrelevant and incorrect choice.
Option C: The statement 'Rohit is the son of Ganesh' clearly identifies Ganesh as the father, not the mother.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning and Family Relations as background academic context rather than a clinical decision trigger.
While not a clinical question, this type of logical reasoning is a crucial skill for nurses. It helps in analyzing patient information, identifying missing data, and making sound judgments without making assumptions.
Nurses must be able to connect different pieces of patient data (like symptoms, lab results, and history) to form a coherent clinical picture, similar to connecting relationships in a logic puzzle.
What if the question added the sentence, 'Ganga is Ganesh's wife'? In that case, the answer would change to 'Ganga'. This demonstrates the importance of ensuring all necessary information is present before drawing a conclusion, a vital principle in patient assessment.

How to Approach the Question

First, carefully read all the statements provided in the question to identify each character and their relationship to others.
Create a simple mental map or a quick sketch of the family tree. For instance: Ganesh (Father) has two sons, Rohit and Dilip.
Identify the specific question being asked. Here, it is 'Who is Rohit's mother?'.
Review your map and the original statements to see if the mother is mentioned. You will find that her name is not provided.
Evaluate the given options. Eliminate choices that are logically impossible (e.g., Rohit being his own mother) or introduce information not present in the text (e.g., Dinesh).
Conclude that since the necessary information is missing, the answer cannot be determined from the text.
