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’?
Wife's Father
Wife's Brother
Father
Brother
Wife's Brother
Break the expression into segments: S-D (Brother), D+F (Son of), F÷G (Father), G×H (Wife). Trace from S towards H.
Break the expression into segments: S-D (Brother), D+F (Son of), F÷G (Father), G×H (Wife). Trace from S towards H.
Analyze the expression
Expression is S - D + F ÷ G × H. Break it down: (S-D) is S is brother of D; (D+F) is D is son of F; (F÷G) is F is father of G; (G×H) is G is wife of H.
Establish Relationships
If F is father of D and G, and D/G are siblings, then S (brother of D) is also the son of F and brother of G.
Final Link
G is the wife of H. Since S is the brother of G, S is the brother of H's wife, which is 'Wife's Brother'.
A: Wife's father is incorrect because S belongs to the same generation as G. C: Father is incorrect as F is the father, not S. D: Brother is imprecise as it doesn't account for the marital link to H.
B is correct because S is the brother of G, and G is the wife of H, making S the brother-in-law (Wife's Brother) to H.
In blood relations with symbols, always draw the generation tree starting from the parent to avoid confusion regarding seniority.
