Blood Relation Questions and Answers

Answer: A

The lady is Rajan's Aunt.

Work from Rajan outwards. The husband of my mother is my father. The woman who is the mother of my father is my paternal grandmother. Her daughter is my father's sister, that is my aunt.

Granddaughter and daughter run the relationship the wrong way, and sister would need the lady to be a daughter of Rajan's mother, not of his grandmother.

Answer: A

B and F are wife and husband.

Read the expression A X B * C - D X F one symbol at a time:

• A X B: A is the daughter of B.
• B * C: B is the mother of C.
• C - D: C is the brother of D.
• D X F: D is the daughter of F.

B is the mother of C, and C is D's brother, so B is D's mother too. D is also the daughter of F. A child's two parents are her mother B and her father, so F is the father, and B and F are wife and husband.

Nothing makes B and F siblings, and neither is the other's child, so the remaining options fail.

Answer: A

Pushpa is the woman's sister.

Pushpa's grandfather's only son must be Pushpa's father, since her father is a son of her grandfather and there is only one son. The woman is the daughter of Pushpa's father, so she and Pushpa are daughters of the same father, which makes Pushpa her sister.

Nothing puts the two women in different generations, so mother, daughter and niece are all ruled out.

Answer: B

P is the sister of T.

Decode P + Q − R × S ÷ T one link at a time:

• P + Q: P is the daughter of Q.
• Q − R: Q is the father of R.
• R × S: R is the son of S.
• S ÷ T: S is the mother of T.

Q is R's father and S is R's mother, so Q and S are a couple. P is Q's daughter, and S is T's mother, so P, R and T are all children of Q and S. Since P is female (a daughter), P is T's sister.

Nothing places P in T's parents' generation, which rules out 'wife'. S, not T, is the mother of the family, which rules out the options making T a mother or grandmother.

Answer: A

J is a nurse.

K is the father of N, and M is N's grandmother, so M belongs to the older generation. O is L's grandfather, so O is also of the older generation; with two married couples in the family, O and M are one couple, the grandparents. N and L are the grandchildren, and K, a parent, forms the second couple with J, the other parent.

The professions: K is the doctor, O the contractor and M the housewife, and the two students must be the children, N and L. The only profession left is nurse, so J is the nurse, and J is K's wife.

Doctor, contractor and housewife are already taken by K, O and M.

Answer: A

X could be R's wife.

S is the maternal uncle of A, so S is the brother of A's mother. S is also the brother of X, so X is A's mother (X must be a woman, since a maternal uncle is the mother's brother).

A and B are brothers and R is B's father, so R is also A's father. A's mother X is therefore the wife of A's father R.

'Mother' would make X the grandmother of A, but X is A's mother. 'Brother' and 'Uncle' are male, while X, as A's mother, must be female.

Answer: A

B is Y's maternal uncle.

A is the mother of X, and X and Y are brothers, so A is also the mother of Y. B is the brother of A, which makes B the brother of Y's mother: Y's maternal uncle.

B cannot be Y's mother, since B is a brother, a male. He is not Y's brother or father: he belongs to the generation of Y's mother, on her side of the family.

Drawing a quick family tree helps: put A at the top with her children X and Y below, and B beside A as her brother. B is then one generation above Y, on the mother's side.

Answer: C

The man is her Cousin.

The brother of her mother is her maternal uncle. The son of her maternal uncle is her first cousin.

He cannot be her son, who would be described as her own child, not as her uncle's son. Nothing in the description makes him her husband. Since a relationship can be named, 'None of these' is wrong.

Answer: B

Rajiv is Sonia's Son.

Atul is the son of Sonia, and Rajiv is the brother of Atul, so Rajiv is also Sonia's child. Being a brother, he is male, so he is her son.

The statement that Sonia is the sister of Sunil is a distractor; it tells us about Sunil, not Rajiv. Rajiv would be Sunil's nephew, which is why 'Nephew' is the trap answer. 'Brother' is his relation to Atul, not to Sonia.

Answer: C

The expression meaning R is uncle of T is P*R#Q@S*T.

Read it pair by pair: P*R means P is father of R; R#Q means R is brother of Q; Q@S means Q is sister of S; S*T means S is father of T. So R is a brother of T's father S, and a father's brother is an uncle.

• R*P#S∆Q@T: R is father of P; P is brother of S, who is mother of Q, and Q is sister of T. So R is T's grandfather.
• S*P#R*U#T: R is father of U, and U is brother of T, so R is T's father.
• P*R@Q@S*T: R@Q makes R a sister, so R would be T's aunt, not uncle.
