Blood Relation Questions and Answers

Answer: A

F is the father of L.

Decode the symbols: F & G means F is the husband of G; G % K means G is the mother of K; K + L means K is the sister of L. K and L are sisters or sister and brother, so G is also the mother of L. F, being G's husband, is therefore L's father.

Mother and sister would apply to a woman, and brother would need a different symbol chain, so only father fits.

Always work through the chain in order. The husband of G is F, G is the mother of K, and K is a sister of L, so G is the mother of both K and L. That means F is the father of L, not a brother (which would need a male symbol) and not a sister or mother (which need a female).

Answer: C

The minimum is 10 members. Take a grandfather and grandmother, their son A and his wife, and their daughter C and her husband. Then A has a son and a daughter, and C has a son and a daughter. Fathers: the grandfather, A and C's husband, 3. Mothers: the grandmother, A's wife and C, 3. Sons: A and the two grandsons, 3. Daughters: C and the two granddaughters, 3. Nieces: each granddaughter is the niece of the other's parent, 2. Nephews: likewise 2. The son-in-law is C's husband and the daughter-in-law is A's wife. The count is 2 + 2 + 2 + 4 = 10, and each person fills several roles, so no smaller family fits. The larger numbers 11, 12 and 13 would need extra people.

Answer: B

U is the son's wife of Y. Decode T ÷ U + V × W − X × Y: T is the father of U; U is the wife of V; V is the son of W; W is the mother of X; X is the son of Y.

W is the mother of both V and X, so V and X are brothers, and X is Y's son, which makes Y the parent of V as well. U is V's wife, so U is the wife of Y's son, which is the son's wife (daughter-in-law) of Y. Daughter, sister and mother would all need U to be a blood relative of Y, which no link in the chain gives.

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.
