In a family, P is the father of Q, and Q is the sister of R. S is the son of R, and T is the wife of P. Which of the following is definitely true about the gender of the persons?
P is definitely male because P is described as the father of Q. R's gender cannot be determined, S is a son and so male, and T is a wife and so female.
- AR is male
- BP is maleCorrect
- CS is female
- DT is male
Explanation
P is a father, so P is male. R's gender is not given because 'sister of R' says nothing about R. S is the son, so S is male, ruling out S female. T is the wife of P, so T is female, ruling out T male.
