Blood Relation Questions and Answers

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.

Answer: D

B is E's brother, so the answer is None of the above.

C is the wife of B, and D is the father-in-law of C, so D is B's father. D is also the father of E, so B and E are siblings. B is a husband and the father of F, so B is male: B is E's brother.

The rest fits: the two married couples are B and C, and D and G (the housewife, B's mother). A and F are the children of B and C, so A is G's granddaughter.

'Sister' gets B's sex wrong, and 'Uncle' and 'Cousin' put B in the wrong generation or branch, when B and E are children of the same father, D.

Answer: D

C is A's son.

A and D are brothers. B is married to D, so E, who is married to one of the brothers, must be A's wife. G is the child of B and D. The family has 3 children, F, G and C; E has two of them, so F and C are the children of A and E.

F and G are the only girls, so C is a boy, the son of A (and E). C cannot be G's brother (G's parents are B and D), and he is a child, not anyone's father.

The 4 adults are A, D, B and E, which confirms the structure: two brothers and their wives.

Answer: B

The valid inference is A is the husband of D.

A, E (sons of F) and B (son of A) are males, so with equal numbers the other three, C, D and F, are female. D is the mother of a boy and a girl; the only boy who is not F's son is B, and the only girl available is C, so D's children are B and C.

B is A's son, so D is A's wife, and since there is only one married couple, A and D are it. A, B and C are not all female; E and F are not D's children (F is the elder generation); and D is F's daughter-in-law, not granddaughter.

Answer: B

There are 3 male members.

• P and R are brothers, so both are male.
• S is R's only son, so S is male.
• P and Q are a married couple; with P male, Q is P's wife.
• T is S's sister and U is P's mother, so both are female.

So the males are P, R and S, and the females are Q, T and U. The answer 2 forgets one of the brothers or the son, and 4 counts Q as male.

Answer: B

The expression is A*U÷J*M.

Decode it link by link:

• A*U: A is the husband of U.
• U÷J: U is the daughter-in-law of J.
• J*M: J is the husband of M.

U is the daughter-in-law of J and his wife M, and U's husband is A, so A is the son of J and M, and therefore the son of M.

The first and third options begin with A÷ or A−, which make A a daughter-in-law or a wife, so A would be female. In the last option, A is the husband of U, U is J's sister, and J is M's wife, which makes A the husband of M's wife's sister, not M's son.
