Question

In a certain code language, A + B means ‘A is the sister of B’, A – B means ‘A is the father of B’, A x B means ‘A is the brother of B’ and A ÷ B means ‘A is the wife of B’. How is P related to T if ‘P x Q ÷ R – S + T’?

• A. Mother’s brother
• B. Father’s brother
• C. Sister’s husband
• D. Daughter’s son

Answer 1

Answer:

A. Mother’s brother

P is the paternal uncle (father's brother) of T.

We can decode the expression P x Q ÷ R – S + T piece by piece from left to right:

1. P x Q: P is the brother of Q. (P is Male)

2. Q ÷ R: Q is the wife of R. This means R is the husband of Q. (Q is Female, R is Male)

3. R – S: R is the father of S.

4. S + T: S is the sister of T. (S is Female)

## Conclusion

* Since R is the father of S, and S is the sister of T, R is the father of T.

* Q is married to R, so Q is the mother of T.

* P is the brother of Q, making P the maternal uncle (mother's brother) of T.
