P is wife of Q and mother of R. R is grand-daughter of W. S is grandmother of T and mother of Q. Which of the following is true?
- a.R is sister of T.
- b.R is brother of T.
- c.Q is daughter of S.
- d.None of the above
Answer: (A) R is sister of T.
From the given data: S is mother of Q (so Q is son or daughter of S), and Q is husband of P. S is grandmother of T. R is the granddaughter of W. P is mother of R. Q is a male (husband of P). Since S is mother of Q and grandmother of T, T is Q's child — making T a sibling of R. Since R is a granddaughter (female), and the diagram shows R is sister of T, option A is correct.
