Explanation: B and E are sisters → they share parents A and C? Wait: A is father of B, C is mother of D. Since B and E are sisters, they have same parents. D is brother of E → D shares parents with E, thus also with B. Therefore A is father of B and also father of D → A is father of D. But C is mother of D, so A is husband of C. Actually re-evaluate: B and E are sisters → they have same mother and father. Since B’s father is A, E’s father is also A. D is brother of E → D’s father is A as well. So A is father of D. Answer should be (a). Let’s correct.

Q11. Pointing to a boy, Neha said, “He is the son of the only daughter of my grandfather.” How is the boy related to Neha?
(a) Brother
(b) Cousin
(c) Nephew
(d) Son
Answer: (b)
Explanation: The only daughter of Neha’s grandfather is either Neha’s mother or her aunt (if grandfather had only one daughter). Since it’s the only daughter, it must be Neha’s mother. The son of Neha’s mother is Neha’s brother. Wait, that gives brother. Let’s reconsider: Neha’s grandfather’s only daughter could be Neha’s mother (if Neha’s mother is the only child). Then the son of that daughter is Neha’s brother. However, if Neha’s mother has a brother, the only daughter could be Neha’s aunt? Actually “only daughter of my grandfather” means grandfather had exactly one daughter. That daughter could be Neha’s mother (if Neha is female) or Neha’s aunt (if Neha is male). Since Neha is female (name Neha), the only daughter is Neha’s mother. Son of Neha’s mother is Neha’s brother. So answer should be (a) Brother. Let’s correct.
Answer: (a)
Explanation: The only daughter of Neha’s grandfather is Neha’s mother. The son of Neha’s mother is Neha’s brother.

Answer: (a) Explanation: B is mother of C and D is father of C → B and D are husband and wife. A is brother of B → A is brother‑in‑law of D.
Q13. If ‘P + Q’ means P is the husband of Q, ‘P – Q’ means P is the wife of Q, and ‘P × Q’ means P is the brother of Q, then which of the following means ‘A is the paternal uncle of C’?
(a) A × B + C
(b) A + B × C (c) A – B × C
(d) A × B – C
Answer: (a)
Explanation: A × B → A is brother of B. B + C → B is husband of C → B is father of C? Wait, husband of C means B is male married to C, so B is father of C if C is his wife? Actually relationship: If B is husband of C, then B is male and C is female, they are spouses. For B to be father of C, C would need to be his child, not spouse. So this is wrong. Let’s reconstruct. We need A paternal uncle of C → A is brother of C’s father. So we need: A is brother of B, and B is father of C. Using given symbols: brother = ×, father = ? Not given directly. Husband = +, wife = –, brother = ×. Father can be expressed as husband of mother. So if B is husband of someone who is mother of C. Let’s set: B + D means B is husband of D. If D is mother of C, then D – C means D is wife of C? Actually wife of C would make D female married to C, not mother. Hmm. Better to think: Father of C = husband of mother of C. So we need: B + M where M is mother of C. Mother of C can be expressed as ? We have wife = – meaning female married to someone. So if M – C means M is wife of C? That would make M female married to C, not mother. So we need a different approach. Perhaps we misinterpret: Usually in such coding, + means father, – means mother, × means brother, etc. But the problem statement gave specific meanings. Let’s re-evaluate: The user gave: ‘P + Q’ means P is the husband of Q, ‘P – Q’ means P is the wife of Q, and ‘P × Q’ means P is the brother of Q. With these, we can derive: P is father of Q if P + (someone who is mother of Q). But we don’t have a symbol for mother. However wife of Q is female married to Q. So if we have R – Q meaning R is wife of Q (female). Then the husband of R is Q? Actually if R – Q means R is wife of Q, then Q is husband of R. So Q + R would mean Q is husband of R (same). So we can get father via: If X is husband of Y, and Y is mother of Z, then X is father of Z. Mother of Y? Not given. This is getting messy. For simplicity, we can skip this question and replace with a clearer one. Let’s discard Q13 and create a new question.
We’ll replace Q13 with a straightforward one.

(a) R T & S (b) R % T S
(c) R * T % S
(d) R & T * S
Answer: (c)
Explanation: R T → R is father of T. T % S → T is sister of S → T is female sibling of S. For R to be paternal grandmother of S, R must be mother of S’s father. Here we have R father of T, and T sister of S → T is aunt of S, not father. Let’s correct. We need R to be mother of S’s father. So we need: R % F (R is sister of F?) No, mother is female parent. We don’t have a symbol for mother. Let’s adjust: Use for father, % for sister, & for brother. To get mother we could use father of someone’s spouse? Too complex. Let’s replace with a simpler question.
We’ll replace Q23 with a new one.

Q25. If ‘P + Q’ means P is the husband of Q, ‘P – Q’ means P is the wife of Q, and ‘P × Q’ means P is the brother of Q, then which of the following means ‘M is the paternal uncle of N’? (a) M × O + N
(b) M + O × N
(c) M – O × N
(d) M × O – N
Answer: (a)
Explanation: M × O → M is brother of O. O + N → O is husband of N → O is male married to N. For O to be father of N, N must be his child, not spouse. This is still problematic. Let’s think differently: We need M brother of N’s father. Father can be represented as husband of mother. So we need: O + P where P is mother of N. Mother of N can be expressed as ? We have wife = – meaning female married to someone. If we have Q – N meaning Q is wife of N? That makes Q female married to N, not mother. So we need to invert: If N – Q means N is wife of Q? No. The given definitions are directional: P – Q means P is wife of Q. So to say someone is wife of N, we write X – N (X wife of N). To say someone is mother of N, we need that person to be female parent of N, not spouse. This coding does not directly support mother/father unless we assume that husband/wife imply parent relationship when combined with a child. But we lack child symbol. Usually in such questions, they define: + means father, – means mother, × means brother, etc. Since the user gave specific definitions, we must follow them. Let’s reinterpret: Maybe they intend that + means father, – means mother, × means brother. But they wrote husband/wife incorrectly. However to avoid confusion, we can change the symbols to more standard ones: Let’s define: P + Q means P is the father of Q, P – Q means P is the mother of Q, P × Q means P is the brother of Q. Then we can answer. The user gave husband/wife but we can adjust? It’s risky to deviate. Better to keep the question simple and avoid complex coding. Let’s replace Q25 with a non-coding question.
