Break the expression into individual segments: S+E (S is sister of E), E-W (E is brother of W), WxT (W is wife of T), T/N (T is father of N). Then trace the relation from S to N.
Deconstruct the expression
S + E means S is the sister of E. E - W means E is the brother of W. W x T means W is the wife of T. T ÷ N means T is the father of N.
Analyze family structure
Since W is the wife of T and T is the father of N, W must be the mother of N. Since S is the sister of E and E is the brother of W, S, E, and W are siblings. Therefore, S is the sister of N's mother.
Determine relation
S is the sister of W (N's mother), therefore S is the Maternal Aunt or Mother's sister of N.
B: S is not the direct sister of N; she is the aunt. C: W is the mother, not S. D: S is the sister of the mother, not the mother of the mother (grandmother).
A is correct because S is the sister of W, and W is the mother of N, making S the mother's sister (maternal aunt) of N.
