If
a + b means a is the sister of b,
a − b means a is the brother of b,
a × b means a is the daughter of b,
a ÷ b means a is the mother of b,
which of the following shows that p is the wife of r?
Answer and explanation
Correct answer A
The expression is p ÷ q × r. It says p is the mother of q and q is the daughter of r; since q already has p as her mother, r is q's father, so p is r's wife. In p − q × r, p is a brother, so p is male. In p + q × r, p is q's sister and so another daughter of r. In p + q − r, p and r are siblings.
