Blood Relation Questions and Answers

Answer: C

P x Q - R + S gives: P is the father of Q, Q is the brother of R, and R is the husband of S. So P is the father of R, and R is the husband of S, which makes P the father-in-law of S.

Brother-in-law and brother would be the relations of a person of the same generation as S, and father alone would ignore that the link goes through S's husband R. So P is S's father-in-law.

Answer: A

S is C's uncle's sister. The sister of C's mother is C's maternal aunt, and the husband of that aunt is C's uncle. S is the sister of that uncle, so S is a woman who stands to C as the uncle's sister.

The chain can be written as mother's sister, then her husband, then his sister, which gives uncle's sister. The option "Sister's uncle" turns the relation around, since C is not S's sibling's relative in that way. "Uncle" is wrong because S is a woman. "Sister" is wrong because S is not a daughter of C's parents; she belongs to the uncle's family.

Answer: B

B is the mother-in-law of X. Decode the chain ‘X & Z $ A = Y + B ÷ Z’ step by step: X & Z means X is the wife of Z; Z $ A means Z is the brother of A; A = Y means A is the sister of Y; Y + B means Y is the son of B; and B ÷ Z means B is the mother of Z.

So B is the mother of Z, and X is Z's wife, which makes B the mother-in-law of X. ‘Mother’ would need X to be B's own child, and ‘Father’ and ‘Aunt’ are excluded because B is Z's mother and A is Z's sibling.

Answer: C

T is the brother of X. Decode each symbol: in T @ S, T is the brother of S. In S $ U, S is the daughter of U. In U % X, U is the mother of X. So U is the mother of both S and X, which makes S and X siblings. T is male (a brother) and is a sibling of S, so T is also a sibling of X, that is, X's brother.

Husband and wife are ruled out because no # relation links T to X, and sister is ruled out because the relation @ makes T male.

Read left to right: T is S's brother, S is U's daughter, and U is X's mother. Two children of one mother are siblings, and T is male.

Answer: B

Q is the paternal grandaunt of M. Work from M's father: the mother of M's father is M's paternal grandmother, and her husband is M's paternal grandfather. Q is the sister of that grandfather, which makes Q the paternal grandaunt (great-aunt) of M.

A maternal aunt would be the sister of M's mother, so it does not fit. Q cannot be M's father, as Q is a woman, and a sister-in-law would be linked through a spouse or sibling's spouse, not through a grandfather.

Answer: B

U is the daughter of X's daughter, so U is Y's daughter's daughter. The chain U # V @ W * X # Y reads: U is the daughter of V; V is the father of W; W is the son of X; X is the daughter of Y. V is W's father and X is W's parent, so X and V are the parents of W, and U is also V's daughter, which makes U a child of X and V. X is the daughter of Y. Hence U is the daughter of Y's daughter, which is the daughter's daughter. Daughter's son is wrong because U is female, and Daughter or Son would make U a direct child of Y, which the chain does not say.

Answer: D

G is K's daughter. G - H means G is H's sister. H + I means H is I's father. I x J means I is the son of J's brother, so H is J's brother (I's father). J / K means J is the son of K. So K is the father of J and of H. G is H's sister, so G is also K's child, and since G is a sister she is K's daughter. She cannot be K's mother or wife, and the question asks how G is related to K, not to H, so Sister is wrong. Each symbol stands for a relation. The plus sign means father, the minus sign sister, the multiplication sign brother's son and the division sign son. Reading G - H + I x J / K from the left builds the family tree step by step: G and H are siblings, H is the father of I, I is the nephew of J, and J and H are sons of K.

Answer: A

The woman's husband's wife is Shivali herself, so the son of her husband's wife is Shivali's own son. The girl on the stage is the sister of that son, which makes her Shivali's daughter. The girl cannot be Shivali's sister, mother or wife, since a sister of Shivali's son is a child of the same parents and so is a child of Shivali. This is the standard way of solving such puzzles: replace the roundabout phrase by the simple relation and then take the next step. The answer is Daughter, option (A).

Answer: C

Read the expression C - D x F + E - H / G with the given meanings: C is the son of D; D is the father of F; F is the mother of E; E is the son of H; and H is the son-in-law of G. H is the husband of G's daughter, and E is H's son, so F, E's mother, is H's wife and G's daughter. D is F's father and G is also F's parent, so G is D's wife. C is the son of D, so C is the son of G as well. G is therefore the mother of C, option (C). Daughter, sister and wife are not possible, since C is a son of both D and G.

Answer: A

Ramu is Shailesh's father. Ramu says that Shailesh's mother is the only daughter-in-law of Ramu's mother. A daughter-in-law of Ramu's mother is the wife of one of her sons. Ramu is her son, and the only daughter-in-law is the wife of her son Ramu, so Shailesh's mother is Ramu's wife.

Shailesh is therefore Ramu's child, and Ramu is his father. Brother and paternal uncle would mean the woman is the wife of another son, a second daughter-in-law if Ramu was married, and grandfather would make Ramu's mother Shailesh's great-grandmother, which does not fit.
