Wife's father's sister
Break the expression into individual relations and trace the generation gap from S to N: S is the sister of E, E is the father of W, W is the brother of T, and T is the wife of N.
Break the expression into individual relations and trace the generation gap from S to N: S is the sister of E, E is the father of W, W is the brother of T, and T is the wife of N.
Analyze the given expression S + E ÷ W − T × N
S + E means S is the sister of E. E ÷ W means E is the father of W. W - T means W is the brother of T. T × N means T is the wife of N.
Mapping the family tree
Since S is the sister of E, and E is the father of W, S is the paternal aunt of W and T (because W and T are siblings as W is brother of T). T is the wife of N, making N the husband of T.
Final Relationship Determination
T is the wife of N. The father of T is E. The sister of E is S. Therefore, S is the sister of the father of T (N's wife), which is the wife's father's sister.
A: Wife's father's mother is the paternal grandmother, not the aunt. B: Father's sister refers to the relation of the wife to her father, not S to N. D: Wife's sister would imply a direct sibling link to T, ignoring E.
C is correct because the sequence S-E-W-T-N establishes that S is the sister of E, who is the father of T (N's wife), making S the wife's father's sister.
In coded blood relations, always draw a quick sketch of the generation hierarchy to avoid confusion between paternal and maternal sides.
