Blood Relation Questions and Answers

Answer: D

Correct answer: None of these

For M to be N’s maternal uncle, M must be the brother of N’s mother. Taking the options in turn: M + O × N makes O the son of N, so M becomes N’s son, not her uncle. M % O × N + P makes O both M’s daughter and N’s son, which is impossible. M + O % N makes M the brother of O and N the daughter of O - but nothing tells us O is female, so the relation could be paternal. No option establishes it, so the answer is none of these.

Answer: C

Correct answer: Cousin

The brother of her mother is the woman’s maternal uncle, and the man is his son - so the two are cousins.

Answer: B

Correct answer: Father

The daughter of my grandmother is Suraj’s mother, and her only brother is Suraj’s maternal uncle - but the choices offer no uncle. Read the other way, the grandmother’s daughter is Suraj’s aunt, and her only brother is then Suraj’s own father, which is the relation the question is after.

Answer: D

Correct answer: M + K % T x P

M + K makes M the brother of K; K % T makes K the father of T; T × P makes T the sister of P, so P too is K’s child. M is therefore the brother of P’s father - his uncle.

Answer: D

Correct answer: Great-grandson

Correct answer: Mother

The woman’s granddaughter is the daughter of Abhijit’s brother, so that brother is her son - which makes her Abhijit’s mother. She cannot be his mother-in-law, since a mother-in-law’s granddaughter through him would be his own daughter.

Answer: C

Correct answer: Aunt

My mother’s father is Amar’s maternal grandfather, whose only son is Amar’s maternal uncle. The girl’s mother is that man’s sister, so she and Amar’s mother are sisters - making the girl’s mother Amar’s aunt.

Answer: D

Correct answer: Sister

Your mother’s husband is the lady’s father, and his sister is her aunt - and that woman is the speaker’s aunt as well. Sharing a father, the two are siblings, so the lady is his sister.
