P is Q's sister. R is Q's mother. S is R's father. T is S's mother then, how is P related to S?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Granddaughter
Join the relations one link at a time, starting from P and moving up to S.
P is Q’s sister, so P is female, and P and Q have the same mother.
R is Q’s mother, so R is P’s mother too.
S is R’s father, so S is P’s mother’s father, that is, P’s grandfather.
So P, a girl, is S’s granddaughter. (T, S’s mother, is P’s great-grandmother and is not needed.)
