This question was previously asked in
RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

Mother's mother's brother

Decode the expression step by step.

Sid # Kashish: Sid is the brother of Kashish.

Kashish $ Tarun: Kashish is the wife of Tarun.

Tarun % Puneet: Tarun is the father of Puneet, so Kashish (Tarun's wife) is the mother of Puneet.

Puneet @ Aditya: Puneet is the mother of Aditya.

So Kashish is the mother of Aditya's mother, and Sid is Kashish's brother, i.e. Sid is the brother of Aditya's mother's mother.

Hence, the answer is Mother's mother's brother.
