Question

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 P related to T if ‘P + Q ÷ R – S × T’?

• A. Son
• B. Father-in-law
• C. Grandfather
• D. Brother-in-law

Answer 1

Answer:

D. Brother-in-law

P is the wife’s brother’s son (or simply Brother-in-law's son / Nephew) of T.

Let's decode the given expression ‘P + Q ÷ R – S × T’ from left to right:

1. P + Q: P is the son of Q. (P is Male $\rightarrow$ Generation -1)

2. Q ÷ R: Q is the father of R. (Q is Male, and P and R are siblings)

3. R – S: R is the brother of S. (R is Male; P, R, and S are all siblings with Q as their father)

4. S × T: S is the wife of T. (S is Female, which means T is a Male married to S)

## Conclusion

* P, R, and S are siblings (children of Q).

* S is a female who is married to T.

* Therefore, P is the brother of T's wife (S).

* Since the question asks how P is related to T: P is T's brother-in-law (specifically, his wife's brother).
