If a + b means a is sister of b,
a - b means a is brother of b,
a x b means a is daughter of b,
a ÷ b means a is mother of b,
Which of the following relationship shows that p and r are wife and husband?

Solution

Let us verify the options.

Option (A):

p ÷ q, means p is mother of q.

q x r, means q is daughter of r.

The above two statements together tells us that, p is the wife of r. Hence wife and husband relationship exits between p and r.

Therefore option (A) is the answer.

Option (B):

p - q, means p is the brother of q.

q x r, means q is daughter of r.

The above two statements together doesn't tell us that p and r are related as wife and husband.

Hence, Option (B) is not the answer.

Option (C):

p + q, means p is the sister of q.

q x r, means q is daughter of r.

The above two statements together doesn't tell us that p and r are related as wife and husband.

Hence, Option (C) is not the answer.

Option (D):

p + q, means p is the sister of q.

q - r, ,means q is the brother of r.

The above two statements together doesn't tell us that p and r are related as wife and husband.

Hence, Option (D) is not the answer
