In a certain code language

A + B means ‘A is the mother of B’

A – B means ‘A is the sister of B’

A × B means ‘A is the wife of B’

A ÷ B means ‘A is the son of B’

Based on the above, how is Z related to W if ‘Z × Y ÷ X − V + W’?

The correct answer is Mother’s sister’s son’s wife.

To determine how Z is related to W, let us break down the given expression step-by-step based on the defined relationships:

Code Definitions:

1. A + B means 'A is the mother of B'

2. A - B means 'A is the sister of B'

3. A × B means 'A is the wife of B'

4. A ÷ B means 'A is the son of B'

Given Expression:

Z × Y ÷ X − V + W

Let us analyze the relationships starting from the rightmost pair:

1. V + W: V is the mother of W.

2. X − V: X is the sister of V. Since V is the mother of W, X is W's mother's sister (maternal aunt).

3. Y ÷ X: Y is the son of X. Since X is W's mother's sister, Y is the son of W's mother's sister (maternal cousin brother).

4. Z × Y: Z is the wife of Y. Since Y is W's mother's sister's son, Z is the wife of W's mother's sister's son.

Thus, Z is W’s Mother’s sister’s son’s wife.
