Break down the expression into pairs and map relationships sequentially: A-B (Brother), B+T (Mother), T#Y (Daughter), Y%N (Father).
Break down the expression into pairs and map relationships sequentially: A-B (Brother), B+T (Mother), T#Y (Daughter), Y%N (Father).
Analyze the expression Eq - Vc + Tg # Yk % Np
Eq - Vc means Eq is the brother of Vc. Vc + Tg means Vc is the mother of Tg. Tg # Yk means Tg is the daughter of Yk. Yk % Np means Yk is the father of Np.
Build the Family Tree
Since Vc is the mother of Tg and Yk is the father of Tg (because Tg is the daughter of Yk), Vc and Yk are a married couple. Specifically, Yk is the husband of Vc.
Determine the relation
The question asks how Yk is related to Eq. Since Eq is the brother of Vc, and Yk is the husband of Vc, Yk is the sister's husband (brother-in-law) of Eq.
A: Sister's daughter is incorrect as the gender of Yk is male. B: Wife's brother is incorrect as Yk is the husband of the sister, not the brother of the wife. D: Mother's brother is incorrect as Yk is in the same generation as Eq's sister, not the previous generation.
C is correct because Yk is the husband of Eq's sister Vc, making him Eq's sister's husband.
In coded blood relations, always identify gender from the symbols first; if the relation involves a 'husband/father' symbol, the person must be male, which helps eliminate incorrect options quickly.
