Question 1

Encoded relations (+ mother, − brother, % father, × sister): Make P the maternal uncle of Q.  Find the expression that ensures “P is the brother of Q’s mother”. Choose the correct option.

Accepted Answer

Decode the correct chain P − M: P is the brother of M. M + N: M is the mother of N. N × Q: N is the sister of Q ⇒ N and Q are siblings ⇒ they share mother M. ConclusionM is Q's mother and P is M's brother ⇒ P is Q's maternal uncle. Why others don’t work Q − N + M × P links P as sibling of M, but M isn’t shown as Q's mother. P + S × N − Q makes P a mother, not an uncle. Q − S % P relates S and P as father/child; no maternal link to Q.

Question 2

Pointing statement (maternal lineage): Identify the woman’s relation to the man.  Woman: “He is the only son of the mother of my mother.” Determine how the woman is related to the man. Choose the correct relation.

Accepted Answer

Question 6

Blood relations (compound statement parsing): Identify how the lady’s husband is related to Anupam.  Spoken by Anupam to a lady in a car: “The only daughter of the brother of my wife is the sister-in-law of the brother of your sister.”  Use standard…

Accepted Answer

Given data (rewrite with labels) My wife's brother = Anupam's brother-in-law. His only daughter = X. Lady's side: “the brother of your sister” = the lady's brother (LB). Statement: X is the sister-in-law of LB. For a man, “sister-in-law” means either (i) brother's wife, or (ii) wife's sister. Concept/Approach Test which interpretation makes the family graph consistent and also fixes the target relation “lady’s husband” ↔ Anupam. Step-by-step deduction • If X were LB's brother's wife, then X would be the wife of the lady's husband—contradiction (a man cannot have two wives here). So reject (i). • Therefore, X must be the wife’s sister of LB ⇒ LB is married to Y, where Y is X's sister. • X and Y are daughters of Anupam's wife's brother (maternal uncle's daughters). A common, consistent resolution is that the lady is Anupam's daughter; her brother (LB) married his maternal cousin Y (X's sister). Hence the lady’s husband is Anupam’s son-in-law. Quick verification If the lady is Anupam’s daughter, then “the brother of your sister” refers to Anupam’s son (LB). X (maternal-uncle’s daughter) being the sister-in-law of LB is satisfied when LB marries Y (X’s sister). Asked relation then matches: lady’s husband = Anupam’s son-in-law. Common pitfalls Confusing “brother of your sister” with the lady's husband; it refers to the lady's brother, not spouse.

Question 7

Blood relations (chain): Determine Sonia’s relation to Aamir from a nested description.  Aamir says: “She is the wife of the only nephew of the only brother of my mother.”  Work through mother → her only brother → his only nephew to identify who Son…

Accepted Answer

Unpack the chain “Only brother of my mother” ⇒ Aamir’s maternal uncle (unique). “Only nephew” of that uncle ⇒ among the uncle’s siblings’ sons, there is only one male—this is (most parsimoniously) Aamir himself. “Wife of [that only nephew]” ⇒ wife of Aamir. Conclusion Sonia is Aamir’s wife. Common pitfalls Overcomplicating “only nephew”; the minimalist consistent resolution is that Aamir is the only male child among his maternal uncle’s nieces/nephews.

Question 8

Who is M to P? Decide which statements are necessary.  Facts given: M is the father of N, and N is the son of V.  Which additional statement(s) are needed to determine the relation of M to P? (1) P is the brother of V. (2) The daughter of N is the g…

Accepted Answer

Core deduction N is son of V ⇒ V is a parent of N. M is father of N ⇒ M and V are the two parents of N ⇒ M is the husband of V. Determine M ↔ P If (1) P is brother of V, then P is M’s brother-in-law. Relation is fixed. Why (2) is not needed “Daughter of N is granddaughter of V” is a tautology given N is V’s child; it adds no new information about P. Hence only (1) is necessary.

Question 9

Symbolic-kinship decoding: Find the chain that makes U the father-in-law of P.  Operator meanings: A $ B ⇒ A is the brother of B A @ B ⇒ A is the wife of B A # B ⇒ A is the daughter of B A * B ⇒ A is the father of B  Choose the expression in which U…

Accepted Answer

Decode option (a) P @ Q ⇒ P is wife of Q ⇒ Q is P’s husband. Q $ T ⇒ Q is brother of T ⇒ Q and T are siblings. T # U ⇒ T is daughter of U ⇒ U is a parent of T. U * W ⇒ U is the father of W ⇒ U is confirmed male. Since Q & T are siblings and T is child of U, Q is also child of U. Thus U is father of Q, who is P’s spouse ⇒ U is P’s father-in-law. Why others fail (b)–(d) do not anchor U as the father of P’s spouse.

Question 18

Blood relations – precise identification: Pointing to a boy, Sumita said, "He is the son of my grandfather's only son." How is the boy related to Sumita?

Accepted Answer

Introduction / Context:This problem tests core kinship translation. We convert a layered description ("my grandfather's only son") into a direct relation with the speaker (Sumita) and then determine how that person's son relates to her. Given Data / Assumptions: Speaker: Sumita (female). "My grandfather's only son" refers to the sole male child of Sumita's grandfather. Standard, monogenerational family tree; no adoption/step-relations implied unless stated. Concept / Approach:First decode "my grandfather's only son." Sumita's grandfather's only son is Sumita's father. Then the boy in question is "the son of my father," i.e., a male child of her father. Children of the same father (and mother unless otherwise noted) are siblings; since the child is male, he is Sumita's brother. Step-by-Step Solution: Grandfather → his only son = Sumita's father.Boy = son of Sumita's father.Therefore, boy = Sumita's brother. Verification / Alternative check:If the only son were an uncle, Sumita's parent would not be that person. But "only son" leaves no other male child—so it must be her father (otherwise Sumita would have no father or the description would contradict "only"). Hence the boy is necessarily her brother. Why Other Options Are Wrong:Nephew/Cousin/Uncle imply different generations/branches; Son would require Sumita to be the boy's mother, which is not stated or implied. Common Pitfalls:Confusing "grandfather's only son" with "father's only son" or misplacing the generational step. Final Answer:Brother

Question 19

Blood relations – counting definite sons: M is the brother of K. T is the sister of K. R is the father of M. J is the wife of R. How many sons does J have?

Accepted Answer

Introduction / Context:The task is to infer the number of sons of J using given sibling and parent relationships, without over-assuming unspecified genders. Given Data / Assumptions: M is brother of K ⇒ M is male; K's gender unknown. T is sister of K ⇒ T is female; K's gender still unknown. R is father of M; J is wife of R ⇒ J is mother of M (and likely of K, T). Concept / Approach:We know one definite son of J: M. Whether K is a son or daughter is not stated. T is a daughter. Therefore, total sons of J could be 1 (if K is female) or 2 (if K is male). The data does not pin down K's gender. Step-by-Step Solution: Definite male child: M = 1 son.K: unspecified gender ⇒ could add 0 or 1 more son.Hence total sons = 1 or 2 ⇒ not uniquely determined. Verification / Alternative check:Create two consistent family snapshots: (i) K male ⇒ sons = 2; (ii) K female ⇒ sons = 1. Both satisfy all statements, confirming ambiguity. Why Other Options Are Wrong:Any fixed number (1, 2, 3, 4) asserts information not supported by the statements. Common Pitfalls:Assuming K is male because M is a brother; "brother of K" doesn't force K's gender. Final Answer:Data inadequate

Question 20

Blood relations – decode the chain precisely: Pointing to a boy, Urmila said, "He is the son of my grandfather's only daughter." How is the boy related to Urmila?

Accepted Answer

Introduction / Context:We translate a nested family description into a direct relation with the speaker (Urmila). Given Data / Assumptions: "My grandfather's only daughter" ⇒ Urmila's mother (only female child of her grandfather). The boy is the son of that woman (Urmila's mother). Concept / Approach:Child of one's mother is a sibling. The boy is male, so he is Urmila's brother. Step-by-Step Solution: Grandfather → only daughter = mother of Urmila.Boy = son of Urmila's mother ⇒ Urmila's brother. Verification / Alternative check:Had the phrase been "grandmother's only daughter" it still points to mother if she is the only daughter. Either way, the boy remains a son of the mother ⇒ a brother. Why Other Options Are Wrong:"Cousin/Nephew/Uncle/Son" imply different branches or generations not supported by the chain. Common Pitfalls:Misreading "only daughter" as "only child" and overcomplicating with cousin branches. Final Answer:Brother
