In a certain code language,
A + B means ‘A is the mother of B’,
A - B means ‘A is the brother of B’,
A × B means ‘A is the wife of B’,
A % B means ‘A is the father of B’ and
A # B means ‘A is the daughter of B’.
Which of the following means that Q is the sister of the wife of L?
I. V % Q # K + Z - T × L
I. V + Q # K % Z - T + L
I. V # K × Q % L + T # Z
V. V + Q # G - Z % T + L
In Expression I (V % Q # K + Z - T x L), we work backward from the end: T x L establishes that T is the wife of L. Moving left, Z - T makes Z the brother of T, and K + Z identifies K as their mother. Finally, Q # K establishes that Q is also the daughter of K. This makes Q and T sisters. Therefore, Q is indeed the sister of L's wife (T). Other options fail to maintain this specific sibling-to-spouse hierarchy.
