Directions (67-69): Study the following information carefully and answer the questions given below:

J is the wife of K. K is the son of O. N is the aunt of L and K’s sibling. P is the granddaughter of M. Q is married to P. No single parent in the family. Q is the brother-in-law of L. Gender of M is same as P but different as L.

How is Q related to K?

Correct Answer: Son-in-law

To determine the relationship between Q and K, we can break down the information step-by-step to construct the family tree:

1. Analyze J and K:
J is the wife of K. This means J is female (-) and K is male (+), and they are a married couple.

2. Analyze O, K, and N:
K is the son of O. N is K’s sibling and the aunt of L. Since N is an "aunt", N must be female (-).

3. Analyze L:
Since N (K's sister) is the aunt of L, and there are no single parents in the family, L must be the child of the married couple J and K.

4. Analyze M, P, and Q:
P is the granddaughter of M. Since K and N are siblings, and L is a grandchild of M (through K), P must also be a child of K and J, making her a sibling of L.
Since P is a granddaughter, P is female (-).
Q is married to P, which makes Q male (+) and P's husband.
Since Q is married to L's sister (P), Q is indeed the brother-in-law of L.

5. Determine Genders:
The gender of M is the same as P (female, -). Thus, M is female, and since there are no single parents, O must be the husband of M (male, +).
The gender of L is different from P, so L must be male (+).

6. Find Q's relation to K:
P is the daughter of K. Q is married to P.
Therefore, Q is the husband of K's daughter, which means Q is the Son-in-law of K.
