Family Relationship Puzzle Breakdown

This question involves deciphering a family relationship based on a statement made by Anil.

  • Anil is pointing to a boy in a photograph.
  • Anil states: “His father’s sister is the only daughter of my father’s father.”

Analyzing the Relationships

Let's break down the statement step-by-step:

  • "my father's father" refers to Anil's paternal grandfather.
  • "the only daughter of my father's father" means Anil's paternal grandfather has only one daughter. This daughter is Anil's paternal aunt (his father's sister).
  • "His father's sister" refers to the boy's paternal aunt.
  • The statement equates the boy's paternal aunt with Anil's paternal aunt.

Deducing the Connection

If the boy's paternal aunt and Anil's paternal aunt are the same person, it implies that the boy's father and Anil's father are brothers.

  • Both fathers share the same father (Anil's grandfather).
  • Since the grandfather has only one daughter (Anil's aunt), the other children must be sons. Therefore, the boy's father and Anil's father are brothers.

Final Relationship

The question asks how the boy's father is related to Anil.

  • Since the boy's father is the brother of Anil's father, the boy's father is Anil's Father's Brother.

This corresponds to Option A.
