A) Mother

B) Aunt

C) Sister

D) Daughter

Answer

Correct Answer: C

Solution: 1. Amit's paternal grandfather's only son is Amit's father. 2. The woman is the only daughter of Amit's father. 3. Therefore, the woman is Amit's Sister.

Question 2

2. In a family of six people ($A, B, C, D, E, F$), $B$ is the son of $C$ but $C$ is not the mother of $B$. $A$ and $C$ are a married couple. $E$ is the brother of $C$. $D$ is the daughter of $A$. $F$ is the brother of $A$. How many male members are there in the family?

A) 1

B) 2

C) 3

D) 4

Answer

Correct Answer: D

Solution: Let's map the genders and relations: - $C$ is the father of $B$ (since $B$ is the son and $C$ is not the mother). [Male: $C, B$] - $A$ and $C$ are married $\implies$ $A$ is female. [Female: $A$] - $E$ is the brother of $C$. [Male: $E$] - $D$ is the daughter of $A$. [Female: $D$] - $F$ is the brother of $A$. [Male: $F$] Total Male Members: B, C, E, F = 4.

Question 3

3. If $P + Q$ means $P$ is the husband of $Q$; $P \div Q$ means $P$ is the sister of $Q$ and $P \times Q$ means $P$ is the son of $Q$. Which of the following shows that $A$ is the daughter of $B$?

A) $A \div D \times B$

B) $D \times B \div A$

Question 4

4. $K$ is the brother of $X$. $Z$ is the son of $X$. $P$, the daughter of $K$, is married to $N$. $G$ and $X$ are sisters. How is $G$ related to $Z$?

A) Mother

B) Maternal Aunt

C) Sister

D) Grandmother

Answer

Correct Answer: B

Solution: 1. $X$ and $G$ are sisters (both female). 2. $Z$ is the son of $X$. 3. Since $G$ is the sister of $Z$'s mother ($X$), $G$ is the Maternal Aunt of $Z$.

Question 5

5. Pointing to a lady, a man said, "The son of her only brother is the brother of my wife." How is the lady related to the man?

A) Mother-in-law

B) Sister

C) Grandmother

D) Sister of father-in-law

Answer

Correct Answer: D

Solution: 1. Brother of my wife $\implies$ Brother-in-law. 2. The son of the lady's only brother is the man's brother-in-law. 3. This means the lady's brother is the father-in-law of the man. 4. Therefore, the lady is the sister of the man's father-in-law.

Question 6

6. $M$ is the father of $N$ who is the son of $V$. In order to know the relation of $M$ to $P$, which of the following statements is/are necessary? (I) $P$ is the brother of $V$. (II) $V$ is the daughter of $K$.

A) Only (I)

B) Only (II)

C) Either (I) or (II)

D) Both (I) and (II)

Answer

Correct Answer: A

Solution: 1. $M$ is the father of $N$. $N$ is the son of $V$. 2. This implies $M$ (Male) and $V$ (Female) are husband and wife. 3. To find $M$'s relation to $P$, we need to know how $P$ is related to either $M, N,$ or $V$. 4. Statement (I) says $P$ is the brother of $V$. This makes $M$ the brother-in-law of $P$. 5. Statement (II) relates $V$ to $K$, which doesn't help relate $M$ to $P$ unless $P$ is defined via $K$. 6. Thus, only (I) is sufficient.

Question 7

7. 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 $B$; $A * B$ means $A$ is the father of $B$. In the expression $U @ V * W \# X$, how is $V$ related to $X$?

A) Brother

B) Father

C) Husband

D) Son

Answer

Correct Answer: C

Solution: 1. $U @ V \implies U$ is the wife of $V$ ($V$ is Male). 2. $V * W \implies V$ is the father of $W$. 3. $W \# X \implies W$ is the daughter of $X$. 4. Since $W$ is the daughter of both $V$ and $X$, and $V$ is male, $X$ must be female and the wife of $V$. 5. Therefore, $V$ is the Husband of $X$.

Question 8

8. Introducing a boy, a girl said, "He is the son of the daughter of the father of my uncle." How is the boy related to the girl?

A) Cousin

B) Brother

C) Nephew

D) Son

Answer

Correct Answer: B

Solution: 1. Father of my uncle $\implies$ Grandfather. 2. Daughter of grandfather $\implies$ Aunt or Mother. 3. Son of the daughter of grandfather $\implies$ Aunt's son (Cousin) or Mother's son (Brother). 4. Based on standard logical reasoning structures assuming a direct nuclear link when both options are present, the daughter of the grandfather is taken as the mother. Thus, the boy is her Brother.

Question 9

9. $Q$ is the mother of $R$. $P$ is the husband of $Q$. $S$ is the brother of $R$. $T$ is the mother of $P$. How is $S$ related to $T$?

A) Son

B) Brother

C) Father

D) Grandson

Answer

Correct Answer: D

Solution: 1. $P$ and $Q$ are husband and wife ($P$ is father, $Q$ is mother). 2. $R$ and $S$ are their children ($S$ is the son since he is the brother of $R$). 3. $T$ is the mother of $P$. 4. Therefore, $S$ is the Grandson of $T$.

Question 10

10. $A, B, C, D, E$ and $F$ are members of a family. $B$ is the son of $A$ but $A$ is not the mother of $B$. $A$ and $C$ are a married couple. $F$ is the daughter of $A$. $E$ is the brother of $B$. How is $C$ related to $E$?

A) Mother

B) Father

C) Sister

D) Brother

Answer

Correct Answer: A

Solution: 1. $B$ is the son of $A$, but $A$ is not the mother $\implies$ $A$ is the Father. 2. $A$ and $C$ are married $\implies$ $C$ is the Mother. 3. $E$ is the brother of $B$. Since $B$ is the son of $A$ and $C$, $E$ is also the son of $A$ and $C$. 4. Therefore, $C$ is the Mother of $E$.

Accepted Answer

Correct Answer: A

Solution: Check Option A: $A \div D \times B$ 1. $A \div D \implies A$ is the sister of $D$. 2. $D \times B \implies D$ is the son of $B$. 3. If $A$ is the sister of $D$ and $D$ is the son of $B$, then $A$ must be the daughter of $B$. This satisfies the condition.
