In a certain code language, 'A + B' means ‘A is the son of B’, 'A − B' means ‘A is the brother of B’, 'A × B' means ‘A is the wife of B’ and 'A % B' means ‘ A is the father of B’. How is S related to H if ‘S × D + F % G − H’?
Brother's daughter
Brother's wife
Wife
Daughter
Brother's wife
Break the expression into segments from left to right. 'S × D' (S is wife of D) means S is female. Since D is male (S's husband), the relationship follows: S is D's wife, D is F's son, F is G's father, G is H's brother. Thus, S is the wife of H's brother.
Break the expression into segments from left to right. 'S × D' (S is wife of D) means S is female. Since D is male (S's husband), the relationship follows: S is D's wife, D is F's son, F is G's father, G is H's brother. Thus, S is the wife of H's brother.
Deconstruct the expression
Break 'S × D + F % G − H' into parts: (S × D), (D + F), (F % G), and (G − H).
Map relationships
1. S × D: S is wife of D. 2. D + F: D is son of F. 3. F % G: F is father of G. 4. G − H: G is brother of H.
Determine S's relation to H
From the steps, D and G are siblings (children of F). Since G is brother of H, D is also a brother of H. Because S is the wife of D, S is the wife of H's brother.
A: S is not H's daughter. C: S is not H's wife (she is married to H's brother). D: S is not H's daughter.
B is correct because S is the wife of D, and D is the brother of H, making S the wife of H's brother.
In blood relation coding questions, always determine the gender of the individuals first. Since S is defined as a 'Wife' in S × D, S must be female, immediately eliminating any options involving male roles.
