The statement says that R’s only brother’s only sister’s husband is the father of M. Since R has only one sibling, this means R’s sibling is the only sister. R’s brother’s wife would be the sister-in-law, and her husband would be R’s brother.
The husband of R’s brother’s sister (who is R’s sister) is the father of M. Therefore, M’s father is R’s brother.
As a result, M is the child of R’s brother, meaning M is R’s son.
The correct answer is (a) Son.
In a small town lived a close-knit family where every relation could be expressed through simple symbols. For instance, when they said \( A \times B \), it meant \( A \) is the father of \( B \), while \( A \div B \) meant \( A \) is the mother of \( B \). The younger ones were often introduced with \( A + B \), meaning \( A \) was the daughter of \( B \), and the bond of brotherhood was shown by \( A - B \) (A is brother of B).
One day, the children in the family turned these symbols into a playful code. Instead of introducing their parents and siblings in words, they spoke only in symbols. “Look,” giggled little Meena, “\( M + N \div O \)!” Everyone laughed, because they knew it meant Meena was the daughter of \( N \), and \( N \) was the mother of \( O \), making her \( O \)’s sister. What started as a code soon became a family game, making the bonds of father, mother, daughter, and brother not just relations, but symbols of love and togetherness. (165 words)
