Concept:
Decode each symbolic relation step by step to determine the relationship between the given persons.
Solution:
Option (a):
P + R % S – Q
P + R → P is the
mother of R.
R % S → R is the
father of S.
S – Q → S is the
brother of Q.
Thus, R is the father of both S and Q.
Since P is the mother of R, P is the
father's mother of Q.
Hence,
P is the paternal grandmother of Q.
Final Answer:
P + R % S – Q
