Blood Relation Questions and Answers

Answer: C

Correct answer: C @ B % F % E

C @ B makes C the sister of B, so C is female; B % F makes B the son of F, so C too is F’s child; and F % E makes F the son of E. A daughter of E’s son is E’s granddaughter.

Answer: D

Correct answer: None of these

Taking the options in turn: S @ P $ Q makes S the sister of Q’s father - an aunt. Q @ P % S makes P the son of S, so S is a parent of Q - but nothing says S is male, so “father” is not established. Q $ S @ P makes Q the father of S, the reverse of what is wanted. So the answer is none of these.

Answer: D

Correct answer: None of these

Taking the options in turn: P + N * M * Q makes Q the great-grandchild of P, not the other way about. Q * N * M + P puts three generations between Q and P, making him P’s great-grandfather. Q β M β N * P makes Q the brother of P’s father - an uncle. None gives a grandfather, so the answer is none of these.

Answer: B

The correct statement is M is the maternal grandmother of P.

Decode Z @ Y % X $ M * N * J @ P + F step by step: Z is the brother of Y; Y is the son of X; X is the husband of M; M is the mother of N; N is the mother of J; J is the brother of P; P is the daughter of F.

So N is P's mother, and M is N's mother: M is P's mother's mother, the maternal grandmother.

F is P's parent and, since N is P's mother, F is P's father, the husband of N, not the wife. F is X's son-in-law, not his father-in-law. M is a mother, so she cannot be anyone's father.

Answer: B

K is J's father.

H is the daughter of I and L, so I and L are a couple. J is the brother of L's husband, so J is I's brother, and M, J's mother, is also I's mother. H is the granddaughter of K, so K belongs to the grandparent generation, the generation of M.

Of the options, only 'Father' fits that generation: K is M's husband, the father of I and J, which makes H his granddaughter. A brother, son or grandson of J would be in J's generation or below, and could not be H's grandparent.

Answer: D

The man is the brother of the lady's mother-in-law. The lady speaks of the daughter of the man's only sister, and says that girl is the sister of her own husband. A sister of the lady's husband is the husband's sister, so the man's only sister is the mother of the lady's husband, that is the lady's mother-in-law. The man is therefore the brother of the lady's mother-in-law. He is not the father's brother, because the link runs through the husband's mother, and he is not a grandfather or a brother of the father-in-law, because the connecting person is female.

Answer: D

The grandson is Rumana's son. Rumana's father's wife is Rumana's mother (the question takes her to be the mother). The only grandson of Rumana's mother is the son of one of her children, and taking Rumana as that child, he is Rumana's son. 'Grandson' would be a relation of Rumana's parents, not of Rumana herself. 'Brother' would make him the mother's son, not her grandson, and 'Mother' is a different generation altogether. So the relation is son, which the key gives. The question does not rule out a brother's son, but the key reads the relation through Rumana herself.

Answer: D

Take the relation step by step. The only son of Khushboo's mother-in-law is Khushboo's husband, since the mother-in-law is the mother of the husband and he is her only son. The daughter of the husband is Khushboo's own daughter. The husband of that daughter is Khushboo's son-in-law. So the person asked about is Khushboo's son-in-law, and Khushboo is the mother of his wife, that is, his mother-in-law. Mother would be the relation to a child, grandmother to a grandchild and aunty to a nephew or niece, so they do not fit. The answer is mother-in-law, option D.

Answer: B

W is the father-in-law of Z. In W×X+Y−Z, W is the father of X, X is the mother of Y, and Y is the son of Z. Y's mother is X, so Y's father must be Z, which makes X and Z husband and wife. W is the father of X, so W is the father of Z's wife, that is Z's father-in-law. Mother-in-law would need W to be female, which a father is not, and sister or brother would make W a sibling of Z, which the chain does not give.

Answer: B

S is the mother's father of W. Read S ÷ T − U × V + W step by step. S is the father of T. T is the brother of U, so S is also the father of U. U is the mother of V. V is the sister of W, so U is also the mother of W. Hence S is the father of W's mother, that is W's maternal grandfather, which is the mother's father. Father's father would require S to be the father of W's father, and the uncles in the other options would need S to be a brother, not a father.
