Pointing to a boy in a photograph, Sita said, "He is the son of my father's only son." How is the boy related to Sita?
Explanation
Explanation
Step 1: Start from the innermost phrase: "my father's only son". Sita's father's only son is Sita's brother.
Step 2: The boy is "the son of" that brother.
Step 3: A brother's son is the nephew (भतीजा) of the sister.
Step 4: He cannot be Sita's own son, because the statement links him to her brother and not to her.
Answer: Nephew.
