Tarun Unni answered
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.

Juhi Dasgupta answered
Given Information:
A3P means A is the mother of P
A4P means A is the brother of P
A9P means A is the husband of P
A5P means A is the daughter of P

To find:
Which of the following means that K is the mother-in-law of M?

Analysis:
We need to find a code that represents K as the mother-in-law of M. In order to do that, we need to decode the given codes and determine the relationship between K and M.

Solution:
1. Decode the codes:
- A3P: A is the mother of P
- A4P: A is the brother of P
- A9P: A is the husband of P
- A5P: A is the daughter of P

2. Identify the relationship between K and M:
- From the given codes, we can see that K is represented by A in the codes.
- We need to find a code where K is the mother-in-law of M.
- Since K is represented by A, we need to find a code where A is the mother-in-law of M.

3. Determine the relationship between A and M:
- A3P: A is the mother of P
- A4P: A is the brother of P
- A9P: A is the husband of P
- A5P: A is the daughter of P

From the given codes, we can see that A is the mother of P in A3P. Therefore, A is the mother-in-law of P. But we need to find the relationship between A and M.

4. Decode the options:
- Option a) M9N3K4J: A is the brother of P, so it cannot represent K as the mother-in-law of M.
- Option b) M9N5K3J: A is the daughter of P, so it cannot represent K as the mother-in-law of M.
- Option c) K5J9M3N: This option does not represent any relationship between K and M.
- Option d) K3J9N4M: A is the husband of P, so it represents K as the mother-in-law of M.

Conclusion:
Option d) K3J9N4M means that K is the mother-in-law of M.

    Correct answer is option 'B'. Can you explain this answer?

    Elite Coaching Classes answered
    Answer: The girl is Mahesh's sister.
    • "One of my grandfather's sons" refers to Mahesh's father (since Mahesh's father is the son of his grandfather).
    • "The daughter of one of my grandfather's sons" means the girl is the daughter of Mahesh's father, which makes her Mahesh's siste

    If A is the brother of B; B is the sister of C; and C is the father of D, how D is related to A?

      Brother
    • b)
      Sister
    • c)
      Nephew

    Correct answer is option 'D'. Can you explain this answer?

    Stuti Dasgupta answered
    If D is Male, the answer is Nephew.
    If D is Female, the answer is Niece.
    As the sex of D is not known, hence, the relation between D and A cannot be determined.
    Note: Niece - A daughter of one's brother or sister, or of one's brother-in-law or sister-in-law. Nephew - A son of one's brother or sister, or of one's brother-in-law or sister-in-law.

    If M x N means M is the daughter of N; M + N means M is the father of N; M % N means M is the mother of N and M - N means M is the brother of N then P % Q + R - T x K indicates which relation of P to K?
    • a)
      Daughter-in-law
    • b)
      Sister-in-law
    • c)
      Aunt
    • d)
      None of these
    Correct answer is option 'D'. Can you explain this answer?

    Dhruv Saini answered
    P % Q → P is the mother of Q
    Q + R → Q is the father of R
    R - T → R is the brother of T
    Hence, → Q is the father of T
    T x K → T is the daughter of K
    Hence, → Q is the husband of K.
    Therefore, P is the mother-in-law of K.

    A family consists of seven members and three married couples. T is the paternal uncle of N who is married to S. V is the mother-in-law of S. L has only one kid. S and V are the same genders. K is the paternal grandmother of N. T is the son of M.

    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'**.

    If A + B means B is the brother of A; A x B means B is the husband of A; A - B means A is the mother of B and A % B means A is the father of B, which of the following relations shows that Q is the grandmother of T?
    • a)
      Q - P + R % T
    • b)
      P x Q % R - T
    • c)
      P x Q % R + T
    • d)
      P + Q % R - T
    Correct answer is option 'A'. Can you explain this answer?

    Kaavya Nair answered
    Explanation:

    Given Relations:
    - A + B means B is the brother of A
    - A x B means B is the husband of A
    - A - B means A is the mother of B
    - A % B means A is the father of B

    Given Relation for Q as Grandmother of T:
    Q - P + R % T

    Explanation of the Given Relation:
    - Q - P: Q is the mother of P
    - P + R: P is the brother of R
    - R % T: R is the father of T

    Combining the Above Relations:
    Q is the mother of P, who is the brother of R, who is the father of T. So, Q is the grandmother of T.

    Therefore, the correct relation showing that Q is the grandmother of T is:
    Q - P + R % T (Option A)

    Ankita Dey answered
    Introduction:
    In this question, we are given a statement made by Deepak to Nitin regarding a boy playing with a football. We need to determine the relationship between Deepak and the boy playing football based on the given information.

    Given Information:
    Deepak said, "That boy playing with the football is the younger of the two brothers of the daughter of my father's wife."

    Analysis:
    To understand the given statement, let's break it down step-by-step:

    1. "That boy playing with the football": This indicates that the boy being referred to is currently playing with a football.

    2. "The younger of the two brothers": This implies that the boy has an older brother.

    3. "The daughter of my father's wife": This refers to Deepak's sister, as his father's wife is his mother.

    Solution:
    Based on the given information, we can conclude that the boy playing with the football is Deepak's nephew. Here's the step-by-step explanation:

    1. Deepak's father's wife is his mother. Therefore, "the daughter of my father's wife" is Deepak's sister.

    2. The boy playing with the football is the younger of the two brothers of Deepak's sister. This means that the boy is Deepak's sister's son.

    3. Deepak's sister's son is his nephew.

    Conclusion:
    Hence, based on the given information, we can conclude that the boy playing with the football is Deepak's nephew. Therefore, the correct answer is option 'B' - Brother.

    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.

    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.

    Iq Funda answered
    • Ram says, "She is the daughter of the only son of my grandfather."
    • "Only son of my grandfather" refers to Ram's father (since he is the only son of Ram's grandfather).
    • "Daughter of Ram's father" means the woman in the photograph is Ram's sister.
    Therefore, the woman in the photograph is Ram's sister, and Ram is describing his sister.
    The correct answer is: a) Sister.

    Arshiya Mukherjee answered
    Explanation:

    Given Information:
    - P $ Q means P is the brother of Q
    - P # Q means P is the mother of Q
    - P * Q means P is the daughter of Q

    Analysis:
    - A # B: A is the mother of B
    - B $ C: B is the brother of C
    - C * D: C is the daughter of D

    Finding the Father:
    - From the above information, we know that C is the daughter of D.
    - Since C is the daughter, D must be the father of C.
    Therefore, in the expression A # B $ C * D, the father is D. Hence, the correct answer is option A.

    A and B are children of D. Who is the father of A? To answer this question which of the statements (1) and (2) is necessary?
    1. C is the brother of A and the son of E.
    2. F is the mother B.
    • a)
      Only (1)
    • b)
      Only (2)
    • c)
      Either (1) or (2)
    • d)
      (1) and (2) both
    Correct answer is option 'B'. Can you explain this answer?

    Debanshi Saha answered
    A and B are children of D.
    From (1), C is the brother B and son of E.
    Since, the sex of D and E are not known. Hence (1) is not sufficient to answer the question.
    From (2). F is the mother of B. Hence, F is also the mother of A. Hence D is the father of A.
    Thus, (2) is sufficient to answer the question.

    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?

      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.
