RRB ALP 2025 CBT 2 Wiremen Question Paper (28-Jul-2026) (Shift 2)
The correct answer is

Mother's mother

Decode the expression step by step.

Shreya + Dev: Shreya is the mother of Dev.

Dev − Taran: Dev is the brother of Taran, so Shreya is also the mother of Taran (Taran is Shreya's child).

Taran × Harshit: Taran is the wife of Harshit, so Taran is female (Shreya's daughter).

Harshit % Mahak: Harshit is the father of Mahak, and since Taran is his wife, Taran is the mother of Mahak.

Shreya is the mother of Taran, and Taran is the mother of Mahak, so Shreya is Mahak's mother's mother.

Hence, Shreya is Mahak's mother's mother.
