Blood Relation Questions and Answers

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.

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.
