Suresh introduces a man by saying, "He is the son of the woman who is the mother of the husband of my mother." How is Suresh related to this man?

Introduction / Context:

This blood-relation question is slightly tricky because the chain of relations is clear, but it does not uniquely fix the man's position relative to Suresh. The challenge is to recognize that the man could occupy one of two roles (father or paternal uncle), and without extra information we cannot decide which. As part of cleaning the item, we explicitly acknowledge this ambiguity and provide a logically sound "cannot be determined" option.

Given Data / Assumptions:

• Suresh is introducing another man.
• He says: "He is the son of the woman who is the mother of the husband of my mother."
• "The husband of my mother" is Suresh's father.
• "The woman who is the mother of the husband of my mother" is Suresh's paternal grandmother.
• The man introduced is a son of this grandmother.
• We assume no additional clues about the number of sons the grandmother has.

Concept / Approach:

We first simplify the nested phrase "woman who is the mother of the husband of my mother". This gives us Suresh's paternal grandmother. The man is then "a son" of this grandmother, which makes him one of her sons. One of her sons is certainly Suresh's father, but she could also have other sons, who would be Suresh's paternal uncles. Because the question does not specify "only son", we cannot decide definitively whether the introduced man is the father or an uncle.

Step-by-Step Solution:

Verification / Alternative check:

Build two sample families. In Family 1, G has a single son F, who is Suresh's father. The introduced man is F. Then Suresh is his son. In Family 2, G has two sons: F and U. F is Suresh's father, and U is Suresh's paternal uncle. The introduced man is U. The description "son of the woman who is the mother of the husband of my mother" still holds, but now Suresh is his nephew. Both families satisfy the verbal description, proving the ambiguity.

Why Other Options Are Wrong:

Choosing "Son" would incorrectly assume that the introduced man must be Suresh's father, ignoring the possibility of other sons of the grandmother.

"Nephew" would imply the man is Suresh's uncle, again ignoring the equally valid possibility that he is Suresh's father.

"Father" as a direct relation from Suresh to the man is one of the possible answers, but not a guaranteed one; the exam-standard requirement is to mark an answer as correct only when it must hold in all valid cases.

Common Pitfalls:

Many candidates forget that the description "son of my grandmother" does not uniquely identify a person unless "only son" is explicitly stated. In cleaning and validating such questions, it is important to recognize when the information is insufficient and to provide or choose a "cannot be determined" option, rather than forcing a specific relationship.

Final Answer:

From the given data, Suresh's exact relation to the man cannot be determined (he could be either his son or his nephew).
