Understanding the Family Relationships
To decipher how T is related to V, let's break down the information provided:

Family Composition
- The family consists of **seven members**.
- There are **three married couples**.

Key Relationships
- **T** is the paternal uncle of **N**.
- **N** is married to **S**.
- **V** is the mother-in-law of **S**.
- **L** has only one kid.
- **S** and **V** are of the same gender, which implies both are female.
- **K** is the paternal grandmother of **N**.
- **T** is the son of **M**.

Analyzing the Relationships
1. Since **T** is the uncle of **N**, he must be the brother of **N's parent** (either the father or mother).
2. **S**, being married to **N**, makes **V** the mother of **N** (and hence the mother-in-law of **S**), indicating **V** is married to **N's father**.
3. Given that **T** is the brother of **N's parent**, he is the **brother-in-law** of **V**.

Conclusion
Since **T** is the brother of **V's husband**, he is best described as **V's brother-in-law**. Therefore, the correct answer is option **'B'**.

Direction: Study the following information carefully and answer the below questions.
A family has eight members T, S, V, M, N, J, I, and L such that either both or none of the parents are alive. S is married to V who is the mother-in-law of N who is a mother of J. J is the nephew of L who is the brother-in-law of I. T is the grandfather of J. L is unmarried.
Q. Who among the following person is Spouse of M?
  • a)
    S
  • b)
    T
  • c)
    L
  • d)
    V
  • e)
    J
Correct answer is option 'B'. Can you explain this answer?

Understanding the Family Structure
To solve the problem, we need to analyze the relationships given in the information:
- Parents and Grandparents: T is the grandfather of J, which means T is one of the parents. Since either both parents are alive or none are, it implies that S and V (T's children) are likely alive.
- Marital Relationships: S is married to V. V is identified as the mother-in-law of N, indicating that N is married to one of V's children.
- Children Relationships: N is the mother of J. Thus, S and V are J’s grandparents, and N is J's mother.
- Sibling Relationships: J is the nephew of L, which means L is likely the sibling of N.
- Brother-in-law Relationships: L is the brother-in-law of I, suggesting that I is married to L's sibling, potentially N.
- Marital Status of L: L is noted as unmarried, confirming that L cannot be a spouse.
Identifying M’s Spouse
Next, we focus on M’s relationship:
- Since L is unmarried and cannot be M’s spouse, we check other options.
- The only logical conclusion is that M is likely married to T, as T is the grandfather and no other marital status is mentioned.
Conclusion
Based on the relationships established:
- M is the spouse of T.
Thus, the answer to the question "Who among the following person is Spouse of M?" is T.
The correct answer is option 'B'.

Looking at a drawing of a Gentleman, Pinku said, "His mother is the wife of my father's son. Brothers and sisters, I have none." At whose drawing was Pinku looking?
  • a)
    Father
  • b)
    Son
  • c)
    Son-in-law
  • d)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Since Pinku has no brother or sister, he is his father's only son. Now, the wife of my father's son is "my wife." So, Pinku's wife is the Gentleman's mother, meaning the man is Pinku's son.

A is father of O; B is mother of N. The sister of M and O is N. Which of the following statements is definitely not true?
  • a)
    B is the mother of O
  • b)
    M is the sister of O
  • c)
    N is the son of A
  • d)
    B has one daughter
Correct answer is option 'C'. Can you explain this answer?

EduRev CAT answered
“The sister of M and O is N” ⇒ N is female. So calling N “the son of A” is definitely false. The other statements could be true or false depending on whether B is also O’s mother and on M’s gender.

Direction: Study the following information carefully and answer the questions given below.
Eight persons are from the same family with three generations. The number of males is two more than the number of females. W is the brother of T, who is the daughter-in-law of U. F is the brother-in-law of W and father of D. U is the father of F and has only one child. P is the grandmother of O, who is not a female. K is the father of T whereas P is not the mother-in-law of T, who has two children.
Q. If U and P are siblings, then how is U related to K?
  • a)
    Brother-in-law
  • b)
    Sister-in-law
  • c)
    Uncle
  • d)
    Aunty
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Understanding the Family Structure
To determine how U is related to K, let’s break down the relationships based on the information provided.
Family Members and Their Relationships
- U: Father of F, has only one child (F).
- F: Brother-in-law of W, father of D.
- W: Brother of T, daughter-in-law of U.
- T: Daughter of K, has two children.
- K: Father of T.
- P: Grandmother of O, who is not a female.
- The family has more males than females, indicating a male-to-female ratio.
Key Relationships
- U is the father of F, which means F is U's only child.
- W, being the sister of T, means that T is the daughter of K.
- Since W is married to F, U is the father-in-law of W.
Analyzing U and K's Relationship
- Since U is the father of F and F is married to W, it makes U the father-in-law of W.
- T, being the daughter of K and sister to W, makes K the parent of W’s spouse (F).
- Therefore, U and K are connected through their children.
Conclusion
Given that U is the father-in-law of W and W is the sibling of T, U is K’s brother-in-law. This is evident because U is related to K through the marriage of their respective children (F and T).
Thus, the correct relationship is:
U is K's Brother-in-law (Option A).

Y's mother is the sister of P and daughter of M. S is the daughter of Y and sister of T. How is M related to T?
  • a)
    Son
  • b)
    Mother
  • c)
    Grandfather or Grandmother
  • d)
    Father
Correct answer is option 'C'. Can you explain this answer?

S is the daughter of Y, and Y is the daughter of M. Therefore, S is the granddaughter of M. Since T is S's sister, T is also the granddaughter of M. Thus, M is either the grandfather or grandmother of T.

A Boy said to a Woman, "Your mother's husband's sister is my aunt!! How is the Woman related to the Boy?
  • a)
    Sister
  • b)
    Mother
  • c)
    Mother-in-law
  • d)
    All of the above
Correct answer is option 'A'. Can you explain this answer?

Your mother's husband is your father, and your father's sister is your aunt. So, the Woman's aunt is also the Boy's aunt, meaning the Woman is the Boy's sister.

M is the father of O, and P is the son of N. Q is the brother of M. If O is the sister of P, how is N related to Q?
  • a)
    Sister-in-law
  • b)
    Sister
  • c)
    Mother-in-law
  • d)
    Mother
Correct answer is option 'A'. Can you explain this answer?

  • M is the father of O and O is the sister of P.
    This implies M is also the father of P.
  • Since M is the father of both O and P, and P is the son of N,
    it means N is M's wife (because M and N are the parents of O and P).
  • Q is the brother of M.
  • Since N is the wife of M and Q is M’s brother, N is the sister-in-law of Q.
    Correct Answer: a) Sister-in-law.
