A family consists of 8 members and 3 married couples. No single parent has a child. K is the father of H. M is the only son of N. K is the brother-in-law of M. K does not have any siblings. M is the uncle of P. Q is the mother of M. N is the maternal grandfather of C’s son. G is the sister-in-law of C and the daughter-in-law of Q. P and G are of the same gender. M’s sister has only one son. How is N related to Q?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Husband
As no single parent has a child, every child’s father and mother form one of the married couples. M’s parents settle the answer; the rest of the data fits the same family.
M is the son of N, and N is a grandfather, so N is M’s father
Q is the mother of M
M’s father and mother are a married couple, so N is the husband of Q
The whole family, to see that the data fits:
G is the daughter-in-law of Q, and Q’s only son is M, so G is M’s wife
K has no siblings, so K is the brother-in-law of M as the husband of M’s sister
N is the maternal grandfather of C’s son, so C’s son’s mother is N’s daughter, M’s sister; C is this sister, K’s wife, and G is her sister-in-law
H is the son of K and C, the only son of M’s sister
M is the uncle of P, and P is a female like G, so P is the daughter of K and C
Members: N, Q, M, G, C, K, H, P = 8, with the 3 couples N–Q, M–G, K–C
