Blood Relation Questions and Answers

Answer: C

T is the brother of X. Decode each symbol: in T @ S, T is the brother of S. In S $ U, S is the daughter of U. In U % X, U is the mother of X. So U is the mother of both S and X, which makes S and X siblings. T is male (a brother) and is a sibling of S, so T is also a sibling of X, that is, X's brother.

Husband and wife are ruled out because no # relation links T to X, and sister is ruled out because the relation @ makes T male.

Read left to right: T is S's brother, S is U's daughter, and U is X's mother. Two children of one mother are siblings, and T is male.

Answer: B

Q is the paternal grandaunt of M. Work from M's father: the mother of M's father is M's paternal grandmother, and her husband is M's paternal grandfather. Q is the sister of that grandfather, which makes Q the paternal grandaunt (great-aunt) of M.

A maternal aunt would be the sister of M's mother, so it does not fit. Q cannot be M's father, as Q is a woman, and a sister-in-law would be linked through a spouse or sibling's spouse, not through a grandfather.

Answer: B

U is the daughter of X's daughter, so U is Y's daughter's daughter. The chain U # V @ W * X # Y reads: U is the daughter of V; V is the father of W; W is the son of X; X is the daughter of Y. V is W's father and X is W's parent, so X and V are the parents of W, and U is also V's daughter, which makes U a child of X and V. X is the daughter of Y. Hence U is the daughter of Y's daughter, which is the daughter's daughter. Daughter's son is wrong because U is female, and Daughter or Son would make U a direct child of Y, which the chain does not say.

Answer: D

G is K's daughter. G - H means G is H's sister. H + I means H is I's father. I x J means I is the son of J's brother, so H is J's brother (I's father). J / K means J is the son of K. So K is the father of J and of H. G is H's sister, so G is also K's child, and since G is a sister she is K's daughter. She cannot be K's mother or wife, and the question asks how G is related to K, not to H, so Sister is wrong. Each symbol stands for a relation. The plus sign means father, the minus sign sister, the multiplication sign brother's son and the division sign son. Reading G - H + I x J / K from the left builds the family tree step by step: G and H are siblings, H is the father of I, I is the nephew of J, and J and H are sons of K.

Answer: A

The woman's husband's wife is Shivali herself, so the son of her husband's wife is Shivali's own son. The girl on the stage is the sister of that son, which makes her Shivali's daughter. The girl cannot be Shivali's sister, mother or wife, since a sister of Shivali's son is a child of the same parents and so is a child of Shivali. This is the standard way of solving such puzzles: replace the roundabout phrase by the simple relation and then take the next step. The answer is Daughter, option (A).

Answer: C

Read the expression C - D x F + E - H / G with the given meanings: C is the son of D; D is the father of F; F is the mother of E; E is the son of H; and H is the son-in-law of G. H is the husband of G's daughter, and E is H's son, so F, E's mother, is H's wife and G's daughter. D is F's father and G is also F's parent, so G is D's wife. C is the son of D, so C is the son of G as well. G is therefore the mother of C, option (C). Daughter, sister and wife are not possible, since C is a son of both D and G.

Answer: A

Ramu is Shailesh's father. Ramu says that Shailesh's mother is the only daughter-in-law of Ramu's mother. A daughter-in-law of Ramu's mother is the wife of one of her sons. Ramu is her son, and the only daughter-in-law is the wife of her son Ramu, so Shailesh's mother is Ramu's wife.

Shailesh is therefore Ramu's child, and Ramu is his father. Brother and paternal uncle would mean the woman is the wife of another son, a second daughter-in-law if Ramu was married, and grandfather would make Ramu's mother Shailesh's great-grandmother, which does not fit.

Answer: A

F is the father of L.

Decode the symbols: F & G means F is the husband of G; G % K means G is the mother of K; K + L means K is the sister of L. K and L are sisters or sister and brother, so G is also the mother of L. F, being G's husband, is therefore L's father.

Mother and sister would apply to a woman, and brother would need a different symbol chain, so only father fits.

Always work through the chain in order. The husband of G is F, G is the mother of K, and K is a sister of L, so G is the mother of both K and L. That means F is the father of L, not a brother (which would need a male symbol) and not a sister or mother (which need a female).

Answer: C

The minimum is 10 members. Take a grandfather and grandmother, their son A and his wife, and their daughter C and her husband. Then A has a son and a daughter, and C has a son and a daughter. Fathers: the grandfather, A and C's husband, 3. Mothers: the grandmother, A's wife and C, 3. Sons: A and the two grandsons, 3. Daughters: C and the two granddaughters, 3. Nieces: each granddaughter is the niece of the other's parent, 2. Nephews: likewise 2. The son-in-law is C's husband and the daughter-in-law is A's wife. The count is 2 + 2 + 2 + 4 = 10, and each person fills several roles, so no smaller family fits. The larger numbers 11, 12 and 13 would need extra people.

Answer: B

U is the son's wife of Y. Decode T ÷ U + V × W − X × Y: T is the father of U; U is the wife of V; V is the son of W; W is the mother of X; X is the son of Y.

W is the mother of both V and X, so V and X are brothers, and X is Y's son, which makes Y the parent of V as well. U is V's wife, so U is the wife of Y's son, which is the son's wife (daughter-in-law) of Y. Daughter, sister and mother would all need U to be a blood relative of Y, which no link in the chain gives.
