Question

If 'A $ B' means 'A is the brother of B', ${}^{\prime }A@B^{\prime }$ means 'A is the wife of B', '$A\#B^{\prime }$ means 'A is the daughter of B' and ${}^{\prime }A\ast B^{\prime }$ means 'A is the father of B', then which of the following expressions indicate the relationship 'U is the father-in-law of P'?

• A. P@Q$T$\#$U$\ast$W
• B. P@W$Q$\ast$T$\#$U
• C. P@Q$W$\ast$T$\#$U
• D. P@Q$T$\#$W$\ast$U
• E. None of these

Answer 1

The correct option is A P@Q$T$\#$U$\ast$W

P @ Q $\$$ T $\#$ U $\ast$ W
P @ Q $\to$ P is the wife of Q.
Q $\$$ T $\to$ Q is the brother of T.
T $\#$ U $\to$ T is the daughter of U.
U $\ast$ W $\to$ U is the father of W.
Deductions
U is the father of Q, T and W. Q is the husband of P.
Therefore, U is the father-in-law of P.
