Solution: Step 1: Analyze Statement I: 'B is the brother of A'. This tells us B and A share the same parents, and B is male. A's gender is not specified. Step 2: Analyze Statement II: 'B is D's son'. This tells us D is B's parent (mother or father). Step 3: Combine Statement I and Statement II. Since B is D's son and B is A's brother, it means A is also a child of D. Step 4: However, A's gender is still not specified. A could be D's son or D's daughter. Step 5: Therefore, neither Statement I nor Statement II alone or together is sufficient to definitively state A's relation to D.

Solution: Step 1: Decode the relationships in the expression P % Q + R - T x K: - P % Q: P is the mother of Q (P is female). - Q + R: Q is the father of R (Q is male). - R - T: R is the brother of T (R is male). - T x K: T is the daughter of K (T is female). Step 2: Construct the family tree: - P is Q's mother. - Q is R's father. Since R is T's brother, Q is also T's father. - T is K's daughter. Since T is also Q's daughter, K must be Q's wife and T's mother. Step 3: Combine the relationships: P is Q's mother, and Q is K's husband. This makes P the mother-in-law of K. Step 4: Therefore, P is the mother-in-law of K.

Solution: Step 1: Understand the target relationship: I is J's niece. This implies I is female, and I is the daughter of J's sibling. Step 2: Analyze I's gender based on the codes. For I to be female, 'I' must be on the left side of '+' (daughter) or 'x' (sister). Step 3: Evaluate Option 4: I x C + N - J - N - J: N is the brother of J (N is male). - C + N: C is the daughter of N (C is female). - I x C: I is the sister of C (I is female). This confirms I's gender as required for 'niece'. Step 4: Combine the relationships: - I is C's sister. - C is N's daughter. So I is also N's daughter. - N is J's brother. - Therefore, J is I's paternal uncle (as J is N's brother, and N is I's father). Since I is female, I is J's niece. Step 5: This option correctly represents that I is the niece of J.

Solution: Step 1: Analyze Statement I: 'Divya's mother is sister of Shaloo's father'. This means Divya's mother is Shaloo's paternal aunt. Therefore, Divya and Shaloo are cousins. Statement I alone is sufficient to define their relationship. Step 2: Analyze Statement II: 'Shaloo is the daughter of Divya's grandfather's only child'. Divya's grandfather's only child refers to either Divya's father (if paternal grandfather) or Divya's mother (if maternal grandfather). Therefore, Shaloo is the daughter of Divya's parent. This implies that Divya and Shaloo share the same parent, meaning they are sisters. Statement II alone is sufficient to define their relationship. Step 3: Since either Statement I or Statement II alone provides a definitive relationship between Divya and Shaloo, the answer is 'Either I or II is sufficient'.

Solution: Step 1: Analyze the given codes: A $ B → A is the brother of B (A is male) B * C → B is the son of C (B is male) C @ D → C is the wife of D (C is female, D is male) A # D → A is the son of D (A is male) Step 2: From 'A $ B', A is the brother of B. Step 3: From 'B * C', B is the son of C. Step 4: Combining steps 2 and 3, if B is the son of C, and A is B's brother, then A is also the son of C. Step 5: From 'C @ D', C is the wife of D. (C is female). Step 6: Since A is the son of C, and C is female, C is the mother of A. Step 7: The information 'A # D → A is the son of D' further confirms that if C is A's mother, then D must be A's father, which is consistent with C being D's wife.

Solution: Step 1: Understand the target relationship: M is N's maternal uncle. This implies M is male, and M is the brother of N's mother. Step 2: Decode the gender implications of each symbol: - A * B: A is female - A $ B: B is female - A + B: A is male - A = B: B is male Step 3: Evaluate each option to find where M is N's maternal uncle: - Option 1: M = P + Q * N - Q * N: Q is sister of N (Q is female). - P + Q: P is brother of Q (P is male). So P is N's brother. - M = P: P is father of M (P is male). M is P's child. - Result: M is the child of N's brother. (M is N's nephew/niece). Incorrect. - Option 2: N + P = Q * M - Q * M: Q is sister of M (Q is female). - P = Q: Q is father of P (Q is male). This contradicts Q being female. Incorrect. - Option 3: N * P $ Q * M - Q * M: Q is sister of M (Q is female). M's gender is not defined here. - P $ Q: Q is mother of P (Q is female). - N * P: N is sister of P (N is female). - Result: Q is P's mother. N is P's sister. So N is Q's daughter. Q is M's sister. For M to be N's maternal uncle, M must be Q's brother and male. From Q * M, M's gender is not specified; M could be female (maternal aunt). Thus, it does not guarantee M is a maternal uncle. Step 4: Since none of the options definitively and unambiguously establish M as N's maternal uncle, the answer is 'None of these'.

Solution: Step 1: Analyze Statement I. 'The man in the photograph is the only son of Tanya's grandfather.' If Tanya's grandfather has only one son, that son could be Tanya's paternal father or Tanya's maternal uncle (if Tanya's mother is a daughter of the grandfather). Thus, the relationship is not uniquely determined. Statement I alone is not sufficient. Step 2: Analyze Statement II. 'The man in the photograph has no brothers or sisters and his father is Tanya's grandfather.' Since the man's father is Tanya's grandfather, and the man has no siblings, this means the man is the *only child* of Tanya's grandfather. If Tanya's grandfather has only one child, and that child is the man, then Tanya's father must be this man. (If Tanya's mother was a child of the grandfather, the man would have a sister, contradicting 'no brothers or sisters'). Therefore, the man in the photograph is Tanya's father. Statement II alone is sufficient.

Solution: Step 1: M being the maternal uncle of N means M is the brother of N's mother. M must be male. Step 2: Evaluate the option 'M + O % N': * M + O: M is the brother of O (M is male). * O % N: N is the daughter of O (N is female, O is N's parent). Step 3: From these, M is the brother of O, and O is a parent of N. Step 4: For M to be the *maternal* uncle of N, O must be female (N's mother). Step 5: However, the expression 'O % N' only states that N is O's daughter; it does not specify O's gender (O could be N's father or mother). Step 6: Since O's gender is not determined, we cannot definitively conclude that M is N's maternal uncle. Step 7: Therefore, 'None of these' options correctly shows M as the maternal uncle of N.

Solution: Step 1: Analyze Statement I: Kunal says, "She is the mother of my father's only granddaughter." Kunal's father's granddaughter can be either Kunal's own daughter or his sibling's daughter. So, the girl in the photograph could be Kunal's wife (if it's his daughter) or his sister-in-law (if it's his brother's daughter). Step 2: Combine Statement I and II: "Kunal has no siblings." If Kunal has no siblings, then his father's only granddaughter must be Kunal's own daughter. If the girl in the photograph is the mother of Kunal's daughter, then she is Kunal's wife. Therefore, Statements I and II together are sufficient. Step 3: Analyze Statement III: Kunal says, "She is the only daughter-in-law of my mother." If Kunal's mother has only one daughter-in-law, and Kunal is one of her sons, then that daughter-in-law must be Kunal's wife. This statement implies a unique relationship. Therefore, Statement III alone is sufficient. Step 4: Conclusion: The relationship of the girl to Kunal can be determined by either Statements I and II together OR by Statement III alone.

Solution: Step 1: Start analyzing the statement from the end: "my mother." Step 2: "only brother of my mother" refers to Aamir's maternal uncle. Step 3: "only nephew of only brother of my mother" refers to the only nephew of Aamir's maternal uncle. If Aamir's maternal uncle has only one nephew, and Aamir is his sister's son, then that nephew must be Aamir himself. Step 4: The statement simplifies to: "She is the wife of Aamir." Step 5: Therefore, Sonia is Aamir's wife.

Solution: Step 1: Understand that Person A is the brother of Person B's grandmother. Step 2: Recognize that the brother of a grandmother is a granduncle. Step 3: Deduce that Person B is the grandchild of Person A. Step 4: Conclude that Person B is the grandson or granddaughter of Person A. Step 5: Since 'grandson' is an option and fits the relationship, it is the correct answer.

Solution: Step 1: Establish initial relationships from the problem statement: - M is N's father (M is male). - N is V's son (N is male). - From these, M and V are N's parents. Since M is the father, V must be the mother. So, M and V are a married couple. Step 2: Evaluate Statement (1): "P is the brother of V." - If P is V's brother (P is male), and M is V's husband, then M is the brother-in-law of P. - This statement alone is sufficient to determine M's relation to P. Step 3: Evaluate Statement (2): "The daughter of N is the granddaughter of V." - N is V's son. Naturally, N's daughter would be V's granddaughter. - This statement provides no new information about P or the relationship between M and P. Step 4: Conclusion: Only Statement (1) is necessary to determine the relation of M to P.

Solution: Step 1: Analyze Statement 1 - Sangitha is the sister of Manoj. Step 2: Analyze Statement 2 - Rohit's daughter is Sangitha. Step 3: Combine the information to identify Rohit's son. From Statement 2, Sangitha is Rohit's daughter. From Statement 1, Manoj is Sangitha's brother, making Manoj Rohit's son. Therefore, both statements together confirm that Manoj is Rohit's son.

Solution: Step 1: Decode the expression A # B $ C * D step by step. Step 2: A # B → A is the mother of B. (A is female, B is A's child). Step 3: B $ C → B is the brother of C. (B is male, C is A's child, B and C are siblings). Step 4: C * D → C is the daughter of D. (C is female, D is C's parent). Step 5: From the relations, A is the mother of B and C. C is also the daughter of D. Step 6: Since A and D are both parents of C (and B), and A is female (mother), D must be male (father). Step 7: Therefore, D is the father.
