Question

In a certain code language,

A + B means 'A is the sister of B',

A - B means 'A is the brother of B',

A × B means 'A is the wife of B',

A ÷ B means 'A is the father of B'.

If 'S + E - W × T ÷ N', then what is the relation of S with N?

This question was previously asked in
RRB Group D 2025 Question Paper (9-Aug-2026) (Shift 1)
The correct answer is

Mother's sister

Decode the chain step by step. S + E means S is the sister of E. E - W means E is the brother of W, so S and E are both siblings of W, making S the sister of W as well.



W × T means W is the wife of T. T ÷ N means T is the father of N. Since T is the father and W is T's wife, W is the mother of N.



S is the sister of W, and W is the mother of N. Therefore S is the sister of N's mother, i.e., the maternal aunt of N.



Hence, the correct answer is Mother's sister.
