Question

In a certain code language, 'A : B' means ‘A is the wife of B’, 'A × B' means ‘A is the brother of B’, 'A < B' means ‘A is the father of B’ and 'A + B' means ‘A is the mother of B’. How is C related to G if 'C < D × E + F : G’?

• A. Wife's mother's sister
• B. Wife's father's daughter
• C. Wife's daughter's son
• D. Wife's mother's father

Answer 1

Answer:

D. Wife's mother's father

C is the maternal grandfather of G (or G's mother's father).

Let's break down the expression 'C < D × E + F : G' from left to right to build the family relationships:

1. C < D → C is the father of D.

2. D × E → D is the brother of E.

   • This means C is also the father of E.

3. E + F → E is the mother of F.

   • Since C is E's father, C is the grandfather of F.

4. F : G → F is the wife of G.

---

Conclusion

• E is the mother of F.

• C is the father of E (making C the maternal grandfather of F).

• Since G is married to F (F's husband), C is the grandfather of G's wife.

Therefore, C is G's wife's grandfather (maternal grandfather-in-law).
