Pointing to a boy, Meena says: “He is the son of my grandfather’s only son.” How is the boy’s mother related to Meena?

Introduction / Context:We translate “my grandfather’s only son” and then determine the relationship between the boy’s mother and Meena.

Given Data / Assumptions:

• “My grandfather’s only son” = Meena’s father (only male child of her grandfather).
• The boy is the son of Meena’s father.

Concept / Approach:If the boy is Meena’s father’s son, the boy is Meena’s brother (or possibly Meena herself if gender matched, but the statement says “boy”). The boy’s mother is Meena’s mother.

Step-by-Step Solution:Grandfather’s only son → father.Boy = son of father → boy is Meena’s brother.Therefore boy’s mother = Meena’s mother.

Verification / Alternative check:No step requires extra assumptions; “only son” removes ambiguity about which parent.

Why Other Options Are Wrong:Aunt/sister do not fit the mother of Meena’s brother; “data inadequate” is unnecessary.

Common Pitfalls:Misplacing “only son” as applying to the wrong generation.

Final Answer:Mother
