Q1Pointing to a photograph, Meena said, "He is the son of my mother's only daughter." How is the person in the photograph related to Meena?
The phrase "my mother's only daughter" must be resolved first. Meena's mother has only one daughter, and since Meena is speaking, that daughter is Meena herself. The person in the photograph is the son of that daughter. Therefore, the person is the son of Meena. No sister or cousin relationship is possible because the stem rules out another daughter of Meena's mother.
Q2Pointing to a photograph, Meena said, "He is the only son of my mother's father." How is the man in the photograph related to Meena?
Meena's mother's father is Meena's maternal grandfather. The only son of that maternal grandfather is Meena's mother's brother. A mother's brother is called the maternal uncle. The man in the photograph is therefore not Meena's father or grandfather; he is her maternal uncle.
Q3Read the assertion and the reason. Assertion: X is the maternal uncle of Z. Reason: Y is the mother of Z, and X is the brother of Y.
The reason gives two direct facts: Y is the mother of Z, and X is the brother of Y. The brother of one's mother is called the maternal uncle. Since Y is Z's mother, Y's brother X is Z's maternal uncle. Therefore the assertion that X is the maternal uncle of Z is true. The reason is also true as stated, and it is the exact relation chain that proves the assertion.
Q4Asha is the daughter of Bharat. Chirag is the son of Bharat. Disha is the daughter of Chirag. Which statement is incorrect?
Asha and Chirag are both children of Bharat, so they are siblings. Disha is the daughter of Chirag, so Disha is one generation below Asha. Asha is the sister of Disha's father, so Asha is Disha's aunt. Bharat is Disha's grandfather. Sister would require Asha and Disha to have the same parents, which is not given. Therefore, the incorrect statement is that Disha is Asha's sister; she is Asha's niece.
Q5Read the assertion and the reason. Assertion: L is the paternal grandmother of N. Reason: M is the father of N and L is the mother of M.
The reason gives two links: M is N's father, and L is M's mother. Combining them, L is the mother of N's father. The mother of one's father is the paternal grandmother. Therefore, the assertion that L is the paternal grandmother of N is true. The reason is also true as given, and it directly explains why the assertion follows.
