Question

In a certain code language, A ~ B means ‘A is the father of B’, A + B means ‘A is the wife of B’, A = B means ‘A is the brother of B’, A - B means ‘A is the mother of B’. Based on the above, how is C related to F if ‘C ~ H = I - E + F’?

• A. Wife's brother's sister
• B. Wife's mother's son
• C. Wife's sister's brother
• D. wife's grandfather

Answer 1

Answer:

D. wife's grandfather

C is the maternal grandfather of F's wife (or simply, wife's grandfather).

Let's decode the expression C ~ H = I - E + F from left to right:

1. C ~ H: C is the father of H. (C is Male)

2. H = I: H is the brother of I.

   • This means H and I are siblings, and both are children of C.

3. I - E: I is the mother of E. (I is Female)

   • Since I is a daughter of C, E is C's grandchild.

4. E + F: E is the wife of F. (E is Female, F is Male)

Conclusion

• I is the mother of E.

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

• F is married to E.

Therefore, C is the maternal grandfather of F's wife.
