45-48 are based on the followinginformation :

A + B means A is son of B.

A – B means A is wife of B.

A $$\times$$​ B means A is brother of B.

A ÷ B means A is mother of B.

A = B means A is sister of B.

What does P × R ÷ Q means ? 

Correct option is C

​

Based on common conventions in coded blood relation problems:

• P × R typically means P is the brother of R.
• R ÷ Q often means R is the son of Q.

So, putting it together:

• P is the brother of R.
• R is the son of Q, meaning P must be the uncle of Q.

Thus, the correct answer is C: P is Uncle of Q.
