Directions (82-83) : Study the following information carefully and answer the related questions.

There are seven members in a family of three generations. There is no single parent in the family. J is the father-in-law of N who is the father of both R and X. O is the mother of S. A is the only son of J. Female members are more than male members.

How R is related to O?

Correct Answer: Granddaughter

To determine how R is related to O, let us analyze the given family information step-by-step:

Step 1: Analyze the family structure and constraints
- Total family members = 7.
- Total generations = 3 generations.
- Constraint: There is no single parent in the family. This means if any person has a child, their spouse must also be present in the family.
- Constraint: Female members are more than male members. Since there are 7 members, there must be at least 4 females and at most 3 males.

Step 2: Trace the relationships
1. "N is the father of both R and X":
- N is Male (Generation 2 or 3, but since J is father-in-law of N, N is in Generation 2).
- R and X are children of N (Generation 3).
2. "J is the father-in-law of N":
- J is Male (Generation 1).
- Since J is the father-in-law of N, N is married to a child of J.
- Also, N is a parent, so N must have a spouse because there are no single parents.
3. "A is the only son of J":
- J has a son A (Male).
- Since A is the ONLY son of J, and N is married to a child of J, N (who is male) must be married to a daughter of J. Let us call J's daughter N's spouse.
4. "O is the mother of S":
- O is Female (Generation 1, married to J).
- Thus, J and O are the grand-parents in Generation 1.
- Since J and O are parents to A and S, S is the daughter of J and O, and S is married to N.
- So, N (Male) is married to S (Female). S is the mother of R and X.

Step 3: Determine the genders of all members
- Generation 1: J (Male, Father) and O (Female, Mother).
- Generation 2: N (Male, Son-in-law), S (Female, Daughter/N's wife), A (Male, Son of J/O).
- Up to this point, known males = J, N, A (3 males).
- Known females = O, S (2 females).
- Total members so far = 5 (J, O, N, S, A). The remaining 2 members are the children R and X.
- Since the total number of male members cannot exceed 3 (because female members must be more than male members, meaning females ≥ 4), both R and X MUST be female!

Step 4: Answer the specific question
- O is in Generation 1 (Grandmother).
- R is in Generation 3 (Granddaughter, since R is a female child of N and S).
- Therefore, R is the Granddaughter of O.
