Blood Relation Questions and Answers

Answer: A

The correct option is Both (1) and (2) are true.

S and T are sisters and S is Q's daughter, so both are Q's daughters. R is Q's mother, so R is the grandmother of S, and (1) is true. P is Q's brother, so P is the uncle of both S and T, and (2) is true.

Statement (3) cannot be settled: P is a son of R, but Q's gender is not given, so R may have one son or two. Statement (4) is false, because Q has at least two daughters, S and T. That rules out 'Both (1) and (3)', 'Only (3)' and 'Only (4)'.

Answer: B

T is an uncle of S.

Q is R's husband and R is S's mother, so Q is S's father. P is Q's sister, so P is S's aunt (father's sister). T is P's husband, which makes T the husband of S's aunt: an uncle (by marriage).

T cannot be the father, who is Q; nor the grandfather, since T belongs to the same generation as S's parents; nor a brother, for the same reason.

Answer: B

Amit is Ramesh's cousin.

The daughter of Ramesh's grandfather (his father's father) is Ramesh's father's sister, that is, Ramesh's paternal aunt. Amit is her son.

The son of one's aunt is one's first cousin, so Amit is Ramesh's cousin.

Amit is a son, so he cannot be a mother or sister. He cannot be Ramesh's brother either, because his mother is Ramesh's father's sister, not Ramesh's own mother; the trap is to read 'my father has a daughter' as a sister of Ramesh.

Answer: D

Nandani is Madan's niece or daughter.

Sangita is Madan's sister, so Sangita's brother is either Madan himself or another brother of theirs. The statement does not say which.

If the brother is Madan, Nandani, his only daughter, is Madan's daughter. If he is another brother, Nandani is Madan's brother's daughter, his niece. Both readings fit, so the complete answer is 'niece or daughter'.

'Daughter' and 'Niece' alone each pick one case and are incomplete. 'Cousin' is wrong in either case, since Nandani is one generation below Madan.

Answer: A

Y is A's grandfather.

A's father has a son B, so B is A's brother (or A himself). B's aunt C is a sister of one of B's parents, and so of A's parents too.

X is C's husband, so X's father-in-law Y is C's father. C's father is the father of A's parent, which makes Y A's grandfather, paternal or maternal depending on whose sister C is.

Y is two generations above A, so he cannot be A's son or grandson, which are generations below. 'Uncle' would be C's brother or X, not C's father.

Answer: B

The speaker is Pramod's father's wife, that is, Pramod's mother.

The lady in the photograph has a son who is Pramod's maternal uncle, so she is Pramod's maternal grandmother, the mother of Pramod's mother.

The speaker is that lady's only daughter. Pramod's mother is also a daughter of that lady, so the speaker must be Pramod's mother, and so the wife of Pramod's father.

A sister-in-law of Pramod's father would be his wife's sister, which needs the grandmother to have a second daughter, and the word only rules that out. That also removes 'Either (A) or (B)'. 'Neither' is wrong because 'wife' fits.

Answer: B

F's father-in-law is the Grandfather of D's daughter.

F is A's wife, so her father-in-law is A's father, B (B is A's parent, and the question treats B as the father). C is B's mother. E is C's granddaughter, so E is the daughter of one of C's children; read as B's daughter, she is A's sister. D is E's husband, so D's daughter is E's daughter.

B is then the father of E and so the grandfather of E's daughter, who is D's daughter. 'Uncle' and 'Brother' are relations of the same or the next generation, and 'Sister' is a female relation, so none of them fits B, who is two generations above D's daughter.

Answer: B

Only two of the statements are correct.

Statement 1 is correct. The only daughter of the woman's mother is the woman herself, so the man's mother is the speaker.

Statement 2 is correct. The speaker has no siblings, so 'my father's son' is the speaker himself. The person in the photograph has the speaker as father, so he is the speaker's son.

Statement 3 is wrong. Your father's wife is your mother; her only sibling's mother is your mother's mother, that is your maternal grandmother, not your paternal one.

Answer: B

Only two pairs are correctly matched.

Pair 1 is wrong. Your mother's brother's only sibling is your mother herself, not your maternal uncle (the uncle is the mother's brother).

Pair 2 is right. Your father's mother's only son is your father, and your father's daughter is your sister (for a male speaker; for a female speaker the description could be herself, but the intended relation is sister).

Pair 3 is right. Your brother's wife's mother-in-law is her husband's mother, and since he is your brother that is your own mother.

So pairs 2 and 3 hold and pair 1 does not.

Answer: A

1 only is correct.

Statement 1: A is B's father and B is C's brother, so B and C share a parent; within the family, A is also C's father. Correct.

Statement 2: D is E's mother and E is F's sister, so E and F are siblings and D is F's mother as well. D cannot be F's sister, so 'D may be sister of F' is wrong.

The statement 2 trap is to treat 'may be' as always safe; here the relationship is fixed by the premises and rules out sister.
