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 carefully analyze the given information step-by-step to deduce the relationships within the family tree.

Step 1: Identify the key structural information about the family

• Total members = 7
• Number of generations = 3
• Condition: There is no single parent in the family (i.e., every parent present must have a spouse).
• Condition: Female members are more than male members.

Step 2: Analyze the family relationships

1. "J is the father-in-law of N who is the father of both R and X."
- N is a male (father of R and X).
- N is married to the child of J.
- Since N is a father, he and his spouse form Generation 2, while R and X are in Generation 3.
- J belongs to Generation 1.

2. "A is the only son of J."
- Since A is the only son of J, J must also have a daughter who is married to N (because J is N's father-in-law, and N is male).

3. "O is the mother of S."
- There is no single parent, so O must be married to J (forming the top generation, Generation 1) or married to someone else.
- Let's check: J (male, father-in-law) and O (female, mother) form the couple in Generation 1. Their children are A (son) and S / the daughter married to N.
- Since A is the only son, S must be a female (daughter of J and O).
- S is the female child of J and O who is married to N.
- Therefore, N (husband) and S (wife) are the parents of R and X.

Step 3: Determine the gender count

Let's list all 7 members:
1. J: Male (Father/Father-in-law in Gen 1)
2. O: Female (Mother/Mother-in-law in Gen 1)
3. A: Male (Son of J and O in Gen 2)
4. N: Male (Son-in-law, husband of S in Gen 2)
5. S: Female (Daughter of J and O, wife of N in Gen 2)
6. R: Child of N and S (Gen 3)
7. X: Child of N and S (Gen 3)

Currently, we have:
• Males = 3 (J, A, N)
• Females = 2 (O, S)
• Unknown genders = 2 (R, X)

Since female members are more than male members, there must be at least 4 females out of 7. Thus, both R and X must be female.

Step 4: Conclusion

Since R is a female in Generation 3 and O is her grandmother in Generation 1, R is the Granddaughter of O.
