A family consists of three generations. Either both parents are alive or neither is alive. P is the mother of only R and Q. G is the son-in-law of P. L is the daughter of R. N is the maternal grandfather of L. N has one son and one daughter. S is the sister-in-law of R. K is the niece of Q. Which of the following is true?

  1. P is the father of Q
  2. L is the son of S
  3. N is the father-in-law of Q
  4. Q is the brother-in-law of G

Correct answer: Q is the brother-in-law of G

Solution

From P being the mother of only R and Q, R and Q are siblings. Since G is the son-in-law of P, G must be married to P's daughter R, so G is R's husband. N is the maternal grandfather of L, so N is the father of L's mother, i.e., R's father. Therefore Q is R's sibling and hence G's brother-in-law.
