Q's mother is sister of P and daughter of M. S is daughter of P and sister of T. How is M related to T?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Grandfather or Grandmother
Each sentence is read as one link in the family, and the links are joined from M down to T:
Q’s mother is the daughter of M and the sister of P, so P is also a child of M
S is the daughter of P and the sister of T, so T is a child of P
M is the parent of P, and P is the parent of T, so M is T’s grandparent
The question never says whether M is male or female, so M can be T’s grandfather or grandmother.
