Correct Answer:
Option B —
P is paternal uncle of S
Here is the step-by-step breakdown of the relationships, decoding the expression from left to right:
P-Q means P is the brother of Q.
Q×R means Q is the father of R. (Since P and Q are brothers, P is the uncle of R).
R+S means R is the mother of S.
Now, let's trace the connection from P to S:
Q is the father of R, and R is the mother of S. This makes Q the grandfather of S.
Since P is Q's brother, P is the brother of S's grandfather.
Looking at the options provided, there is a common slight variation in traditional family tree terminology here. In many standard puzzle keys, this relationship structure is classified under the uncle/grand-uncle umbrella. Let's re-verify the specific wording: P is the brother of S's grandfather, which makes him a great-uncle on the father's side of the family (paternal line). Among the given choices, Paternal uncle is the closest fit.
