Ravina told Sunil, “Your father’s sister is my mother-in-law.” How is Sunil related to Ravina’s husband?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Cousin
A woman’s mother-in-law is her husband’s mother, and the child of one’s father’s sister is one’s cousin.
Ravina’s mother-in-law is the mother of Ravina’s husband
This lady is the sister of Sunil’s father, that is, Sunil’s aunt
So Ravina’s husband is the son of Sunil’s aunt, and Sunil is his cousin

Why the other options are incorrect
Option (1) Brother — Incorrect. Sunil’s parent is the brother of the husband’s mother, so they do not share parents.
Option (2) Uncle — Incorrect. Sunil’s father is the husband’s uncle; Sunil is in the same generation as the husband.
Option (4) Brother-in-law — Incorrect. Nothing given makes Sunil the brother of Ravina or the husband of her husband’s sister; the link given is by blood, through his father’s sister.
