Vivek said, "This boy is the husband of the only granddaughter of my father." How is Vivek related to the boy?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Father-in-law
Read the statement from the end: “the only granddaughter of my father” is a daughter of one of his father’s children, that is, of Vivek himself or of a brother or sister of Vivek.
In the usual reading she is Vivek’s own daughter.
The boy is her husband, so the boy is Vivek’s son-in-law.
The father of one’s wife is one’s father-in-law, so Vivek is the boy’s father-in-law.
Even if the girl were Vivek’s niece, Vivek would be the uncle of the boy’s wife, not the boy’s own uncle, so Option (4) does not fit.
