1. In option A:- P is great grandmother of Q (P is mother of N is father of M is father Q, 3 generations).
2. In option B:- Q is great grandfather P (Q is the father of N is the father of M is mother of P, 3 generations).
3. In option C:- Q is the uncle of P (Q is the brother of M is brother of N is father of P).
So the last option "None of these" is correct.

If P + Q means P is the brother of Q; P x Q means P is the wife of Q and P % Q means P is the daughter of Q then which of the following means D is the uncle of A?
  • a)
    A % B x C + D
  • b)
    A x B + C % D
  • c)
    A + C % B x D
  • d)
    None of these
Correct answer is option 'D'. Can you explain this answer?

Navya Reddy answered
The correct option is Option A.
A % B x C + D means D is an uncle of A.  
A % B means A is the daughter of B;
B x C means B is the wife of C;
C + D means C is the brother of D.
Thus if B and C are parents to A and C is the brother of D then logically D should be an uncle of A.

Abhay Desai answered
M is the father of N and N is the son of V.
Hence, V is the mother of N.
From (1), P is the brother of V
Therefore, M is the brother-in-law of P because V is the wife of M.
From (2), the daughter of N, is the granddaughter of V. From this we do not get any relation of M to P.

    Kalyan Mehta answered
    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 questions given below.
    A family consists of eight members – G, K, L, O, T, U, V and X and three married couples. X is the father-in-law of G who is the father of U. O is the only daughter of T who is the mother of V. T is the spouse of X. Both U and X are of the opposite gender. K is the mother-in-law of O. L is the paternal grandfather of U.
    Q. Who among the following person is the mother of U?
    • a)
      V
    • b)
      O
    • c)
      L
    • d)
      K
    • e)
      None of the above
    Correct answer is option 'B'. Can you explain this answer?

    Madhavi chauhan answered
    Family Structure Explanation
    To determine who the mother of U is, let’s break down the relationships based on the information provided.
    1. Understanding the Relationships
    - X is the father-in-law of G: This implies that G is married to X's child.
    - G is the father of U: Therefore, G is male since he is referred to as the father.
    - O is the only daughter of T: This indicates that T is O's mother.
    - T is the spouse of X: Hence, T is G's mother as well because G and O are married to X's children.
    - K is the mother-in-law of O: Since O is the daughter of T, K must be T's mother.
    - L is the paternal grandfather of U: This indicates that L is G's father.
    2. Constructing the Family Tree
    - From the above information, we can summarize:
    - X (father-in-law) + T (mother) = G (son) and O (daughter)
    - G (father) + O (mother) = U (child)
    - Therefore, G is married to O.
    3. Identifying the Mother of U
    - Since we established that O is married to G and they have a child named U, it follows that:
    - O is the mother of U.
    Conclusion
    Thus, the answer to the question "Who among the following person is the mother of U?" is:
    Option B: O

    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?

    Madhavi bhatia answered
    Understanding the Family Structure
    To decipher the relationship between U and K, we need to analyze the family tree based on the given information.
    Key Relationships
    - W and T: W is the brother of T. Hence, W and T are siblings.
    - T's Marriage: T is the daughter-in-law of U, indicating that T is married to U's child.
    - F's Role: F is the brother-in-law of W and the father of D. Since W is T's brother, F must be married to W's sister (T).
    - U's Children: U is the father of F and has only one child. This implies that U's only child is F.
    - P's Relation: P is the grandmother of O. Since O is not female, P must be the mother of either W or T.
    - K's Role: K is the father of T, meaning K is married to T's mother, making P K's mother-in-law.
    Analyzing U's Relation to K
    Given that U and P are siblings, we can establish the following:
    - U's Child: U has one child, which is F.
    - F's Marriage: F is married to W's sister (T), making F's wife T's sibling.
    - K's Parentage: Since P is K's mother-in-law, K is married into the family, making U K's brother-in-law.
    Conclusion
    Thus, the relationship between U and K is that U is K's brother-in-law based on the family connections established.
    Therefore, the correct answer is option 'A': Brother-in-law.

    If A $ B means A is the brother of B; A @ B means A is the wife of B; A # B means A is the daughter of B and A * B means A is the father of B, which of the following indicates that U is the father-in-law of P?
    • a)
      P @ Q $ T # U * W
    • b)
      P @ W $ Q * T # U
    • c)
      P @ Q $ W * T # U
    • d)
      P @ Q $ T # W * U
    Correct answer is option 'A'. Can you explain this answer?

    Sagar Sharma answered
    Understanding the Symbols
    - A $ B: A is the brother of B
    - A @ B: A is the wife of B
    - A # B: A is the daughter of B
    - A * B: A is the father of B
    Analyzing Option A
    The expression in option A is:
    P @ Q $ T # U * W
    Let's break it down step by step:
    1. P @ Q: P is the wife of Q.
    2. Q $ T: Since Q is the husband of P and P is the wife, Q must be the brother of T.
    3. T # U: T is the daughter of U.
    4. U * W: U is the father of W.
    From this breakdown, we can infer the relationships:
    - P (Wife of Q)
    - Q (Brother of T)
    - T (Daughter of U)
    - U (Father of W)
    Thus, since P is married to Q, and Q is the brother of T, it follows that U is the father-in-law of P.
    Conclusion
    The relationships outlined in option A clearly establish that U is indeed the father-in-law of P. This makes option A the correct choice to indicate the relationship required in the question.

      Maternal aunt
    • b)
      Grandmother
    • c)
      Sister of father-in-law
    • d)
      None of these
    Correct answer is option 'C'. Can you explain this answer?

    Arnav Choudhury answered
    Brother of person's wife → brother-in-law of the person. Hence, the son of lady's brother is brother-in-law of the person.
    Therefore, the brother of the lady is the father-in-law of the person. Hence, the lady is the sister of the person's father-in-law.

      Sister
    • c)
      Aunt
    • d)
      Cannot be determined
    Correct answer is option 'B'. Can you explain this answer?

    Ayush Rane answered
    The boy in the photograph is the only son of Reena's grandfather's only son; i.e., the boy is the only son of Reena's father.
    Hence, the boy is the brother of Reena or Reena is the sister of the boy.

    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.

      L
    • d)
      V
    • e)
      J
    Correct answer is option 'B'. Can you explain this answer?

    Saptarshi Saini answered
    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'.

    A $ B means A is the father of B; A # B means A is the sister of B; A * B means A is the daughter of B and A @ B means A is the brother of B. Which of the following indicates that M is the wife of Q?
    • a)
      Q $ R # T @ M
    • b)
      Q $ R @ T # M
    • c)
      Q $ R * T # M
    • d)
      Q $ R @ T * M
    Correct answer is option 'D'. Can you explain this answer?

    Baishali Choudhary answered
    Explanation:

    Given Information:
    - $ means father
    - # means sister
    - * means daughter
    - @ means brother

    Analysis:
    To determine that M is the wife of Q, we need to find a relationship between M and Q that indicates they are married. In this case, the relationship that indicates marriage is the one where M is the daughter of Q.

    Applying the Given Symbols:
    - Q $ R @ T * M indicates that Q is the father of R, R is the brother of T, T is the daughter of M. This relationship does not indicate that M is the wife of Q.
    - Q $ R @ T # M indicates that Q is the father of R, R is the brother of T, T is the sister of M. This relationship does not indicate that M is the wife of Q.
    - Q $ R * T # M indicates that Q is the father of R, R is the daughter of T, T is the sister of M. This relationship does not indicate that M is the wife of Q.
    - Q $ R @ T * M indicates that Q is the father of R, R is the brother of T, T is the daughter of M. This relationship indicates that M is the wife of Q.
    Therefore, the relationship Q $ R @ T * M indicates that M is the wife of Q. Hence, option D is the correct answer.

    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?

    Elite Coaching Classes answered
    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.

      I x C - N % J
    • c)
      J + M x C % I
    • d)
      I x C + N - J
    Correct answer is option 'D'. Can you explain this answer?

    Kaavya Kumar answered
    Solution:

    To find out the relation between I and J, we need to look for a combination of symbols that means "I is the niece of J."

    Given:

    - X Y means X is the daughter of Y
    - X - Y means X is the brother of Y
    - X % Y means X is the father of Y
    - X x Y means X is the sister of Y

    We need to find the combination of symbols that means I is the niece of J.

    Explanation:

    - J - N % C x I: This means J is the brother of N, who is the father of C, who is the sister of I. This does not give us the relation we are looking for.
    - I x C - N % J: This means I is the sister of C, who is the daughter of N, who is the father of J. This does not give us the relation we are looking for.
    - J M x C % I: This means J is the daughter of M, who is the sister of C, who is the father of I. This does not give us the relation we are looking for.
    - I x C N - J: This means I is the sister of C, who is the daughter of N, who is the brother of J. This gives us the relation we are looking for. Therefore, option D is the correct answer.

    Final answer: Option D - I x C N - J means I is the niece of J.

    Gopika chauhan answered
    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).

      Father
    Correct answer is option 'C'. Can you explain this answer?

    Elite Coaching Classes answered
    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.
