Question 1

A, B, C, D, E and F are six members of a family. One couple in the family are parents and their children. A is the son of C and E is the daughter of A. D is the daughter of F, who is the mother of E. What relationship do D and E bear to each other?

Accepted Answer

Introduction / Context: This puzzle-style blood relation question presents a six-member family with multiple generations and asks you to determine the relationship between two children, D and E. It is a good example of how to follow parent child links through the family tree and then see whether the two individuals are siblings, cousins or belong to different generations. Given Data / Assumptions: A, B, C, D, E and F are six family members. One couple in the family are parents, and their children also belong to this group. A is the son of C, so C is a parent of A and A is male. E is the daughter of A, so A is the father of E and E is female. D is the daughter of F, who is the mother of E, so F is a female parent of both D and E. This makes A and F the parents of E, and F the mother of D as well. Concept / Approach: The main idea is to identify the parents of D and E. From E is the daughter of A and F is the mother of E, we can see that A and F form the parental couple for E. Then, D is described as the daughter of F. There is no statement that D has a different father; in typical reasoning puzzles, we assume the same husband wife pair for children unless explicitly separated. So D is also a child of F and A, placing D and E in the same generation with the same parents. Therefore, they are sisters. Step-by-Step Solution: Step 1: A is the son of C, so C is a parent of A and A is male.Step 2: E is the daughter of A, so A is E's father, and E is female.Step 3: F is the mother of E, so A and F together are the parents of E.Step 4: D is the daughter of F, so D is another female child of F.Step 5: In the absence of any contrary information, D shares the same father A, making A and F the parents of both D and E.Step 6: Therefore, D and E are daughters of the same parents, making them sisters. Verification / Alternative check: Draw a small tree. Put C as parent of A. A is male. A marries F. They have at least one daughter E (stated) and another daughter D (through F). This is consistent with the statement that F is the mother of E and that D is the daughter of F. There is no indication that F has a different husband for D, and the puzzle hints that a single couple with children is present. Thus, both D and E end up as daughters of the same couple A and F, confirming that they are siblings of the same generation and gender. Why Other Options Are Wrong: Sister and Brother is incorrect because both D and E are described as daughters, so they are both female.Mother and Son would require one of them to be a parent of the other, which is not the case; both are grandchildren of C through A.Grandmother and Granddaughter is impossible because D and E are in the same generation.Cousins would require them to have different parents who are siblings, which is not supported by the data. Common Pitfalls: One common confusion comes from reading F is the mother of E and D is the daughter of F and then imagining that D belongs to a different branch of the family with another father. In typical exam questions, such complications are not introduced unless stated. Another mistake is to forget that both D and E are explicitly daughters, leading to incorrect gender assumptions when choosing between sister brother pairs. Final Answer: D and E are related to each other as Sisters.

Question 2

In a family of six members A, B, C, D, E and F, A and B are a married couple, with A being the male member. D is the only son of C, who is the brother of A. E is the sister of D. B is the daughter-in-law of F, whose husband has died. In this family,…

Accepted Answer

Introduction / Context: This blood relation puzzle describes a six-member family with a married couple, siblings and three generations. The question asks specifically how C is related to B. To answer, you must identify who C's siblings are, who B is married to and where the older generation member F fits in, then translate that structure into a correct relationship term like brother-in-law. Given Data / Assumptions: A and B are a married couple, with A being the male member. D is the only son of C, so C is a parent of D and D is male. C is the brother of A, so C is male and a sibling of A. E is the sister of D, so E is also a child of C. B is the daughter-in-law of F, whose husband has died. Thus F is an older female (a widow) and the parent of A (and likely C). Since B is married to A, B is a child-in-law of F. Concept / Approach: The crucial insight is that C is the brother of A, and B is married to A. The brother of a person's spouse is called a brother-in-law. We must also ensure that there is no alternative role like son-in-law that could apply. Because C is clearly a sibling of A and not a parent of B, the only appropriate relationship description between C and B is brother-in-law. Step-by-Step Solution: Step 1: From A and B are a married couple, with A being the male member, conclude that B is the wife of A.Step 2: From C is the brother of A, deduce that C is a male sibling of A.Step 3: From B is the daughter-in-law of F whose husband has died, infer that F is A's mother (since A is male and B is his wife).Step 4: If F is the mother of A and C is the brother of A, C is also a child of F and thus in the same generation as A.Step 5: Because B is married to A and C is A's brother, C is the brother of B's husband.Step 6: The brother of one's spouse is called a brother-in-law, so C is B's brother-in-law. Verification / Alternative check: Draw a family tree with F at the top as the widowed mother. She has two sons, A and C. A marries B. C has children D (son) and E (daughter). B, as the wife of A, is F's daughter-in-law and C's sister-in-law. There is no information suggesting that C is married to anyone related to B, or that he is B's child or parent, so no other relation like son-in-law or uncle fits better than brother-in-law. Why Other Options Are Wrong: Brother as an answer would be wrong because B and C are not sibling children of the same parents; B married into the family.Son-in-law does not fit because C is not married to F's child; instead C himself is one of F's children.Uncle does not describe the relation between C and B; it might describe how C relates to B's children but not to B herself.None of these is incorrect because brother-in-law exactly matches the described situation. Common Pitfalls: One common confusion is between brother and brother-in-law when a person marries into the family. Another mistake is to look at D and E and think about how C relates to them, rather than staying focused on C's relation to B. Always keep the two target persons in mind and work only through the path that connects them directly, instead of wandering through other branches of the tree. Final Answer: C is related to B as her Brother-in-law.

Question 3

In a family of six members A, B, C, D, E and F, A and B are a married couple, with A being the male member. D is the only son of C, who is the brother of A. E is the sister of D. B is the daughter-in-law of F, whose husband has died. How is F relate…

Accepted Answer

Introduction / Context: This question uses the same six-member family but now asks you to identify how F is related to C. It combines concepts of daughter-in-law, widowed status and siblings to determine the generational position of F relative to both A and C. By correctly placing F in the family tree, you can deduce whether she is a mother, sister, aunt or some other relative of C. Given Data / Assumptions: A and B are a married couple, with A the male member. C is the brother of A, so C is male and a sibling of A. D is the only son of C, and E is the sister of D, so D and E are children of C. B is the daughter-in-law of F, whose husband has died. Thus, F is a female whose son or daughter is married to B. Because A is male and married to B, F must be A's mother (the mother-in-law of B) or A's father's widow. Since C is the brother of A, C is another child of F. Concept / Approach: The key point is that B is described as the daughter-in-law of F. A daughter-in-law is the wife of one's son, so F must be the mother (or at least the parent) of A. Because A and C are brothers, this also makes F the parent of C. The fact that F's husband has died simply explains why only one older person is mentioned from that generation. Therefore, F is the mother of both A and C, making her the mother of C. Step-by-Step Solution: Step 1: Since A and B are a married couple and A is the male member, B is A's wife.Step 2: B is the daughter-in-law of F, whose husband has died. So F is the mother (or parent) of A.Step 3: C is the brother of A, so C and A share parents. Therefore, F is also the parent of C.Step 4: Because F is described as the person whose husband has died, she is a widowed female parent of A and C.Step 5: Altogether, this makes F the mother of C. Verification / Alternative check: Sketch the family tree: F and her deceased husband form the older generation. They have at least two sons, A and C. A marries B, making B the daughter-in-law of F. C has children D and E. In this diagram, F is clearly the mother of both A and C. There is no alternative reading of daughter-in-law and widowed husband that would make F a sister, aunt or sister-in-law of C, since those would place her either in the same generation or a collateral branch, not above as a parent. Why Other Options Are Wrong: Sister is impossible because F is in the older generation as the mother of A's spouse, not in the same generation as A and C.Aunt would require F to be a sibling of one of C's parents, which would still not make B her direct daughter-in-law.Sister-in-law is incorrect because F is not married to a sibling of C; she is instead the parent of C.Grandmother would place F one generation above C, but she is one generation above D and E, not above C. Common Pitfalls: One common confusion is to focus on D and E and mistakenly think of F as their grandmother, forgetting that the question asks about F's relation to C, not to D or E. Another error is misreading daughter-in-law as referring to a more distant relation; in such puzzles it always connects directly to the parent generation of the spouse. Keeping the generational layers clear prevents these mistakes. Final Answer: F is related to C as his Mother.

Question 4

Shobha is the niece of Ashish. Ashish's mother is Priya, and Kamla is Priya's mother. Kamla's husband is Hari. Krishna is the mother-in-law of Hari. Based on these relations, how is Shobha related to Hari?

Accepted Answer

Introduction / Context: This multi-generation family question involves grandparents, great-grandparents and a niece relationship. The aim is to track the generations from Krishna down to Shobha and especially from Hari down to Shobha, and then choose the correct relationship term. Such questions test your ability to handle a family tree that spans four generations. Given Data / Assumptions: Shobha is the niece of Ashish, so Shobha is the daughter of Ashish's sibling. Ashish's mother is Priya, so Priya is a parent of Ashish. Kamla is Priya's mother, so Kamla is the grandmother of Ashish. Kamla's husband is Hari, so Hari is the grandfather of Ashish. Krishna is the mother-in-law of Hari. Therefore, Krishna is the mother of Kamla, who is Hari's wife. We are asked how Shobha is related to Hari. Concept / Approach: The simplest way to proceed is to place the oldest generation at the top and move downward. Krishna is at the top as the mother of Kamla. Kamla and Hari form the next generation as husband and wife. They have a child, Priya, who is the mother of Ashish. Ashish is then one generation further down, and finally Shobha, as the niece (child of Ashish's sibling), is yet another step down. Counting the steps from Hari to Shobha helps us label the relationship correctly as great-granddaughter if there are three generation gaps. Step-by-Step Solution: Step 1: Put Hari and Kamla together as a married couple. They are the grandparents of Ashish because Kamla is Priya's mother and Priya is Ashish's mother.Step 2: Priya, as the daughter of Kamla and Hari, is in the child generation under them.Step 3: Ashish is the child of Priya, so Ashish is a grandchild of Hari.Step 4: Shobha is the niece of Ashish, meaning she is a child of Ashish's sibling (who is also a child of Priya and therefore a grandchild of Hari).Step 5: Thus, Shobha is one generation below Ashish, making her a great-grandchild of Hari.Step 6: A female great-grandchild is called a great-granddaughter. Verification / Alternative check: List the generations explicitly: Generation 1 is Krishna. Generation 2 is Kamla (Krishna's daughter) and Hari (Kamla's husband). Generation 3 is Priya (their daughter). Generation 4 includes Ashish and Ashish's sibling (children of Priya). Generation 5 contains Shobha, who is the child of Ashish's sibling. From Hari to Shobha, we move from generation 2 (Hari) down to generation 5 (Shobha), a difference of three generations. That is exactly the distance of a great-grandchild, confirming Shobha as Hari's great-granddaughter. Why Other Options Are Wrong: Daughter is off by two generations; Hari's daughter is Priya, not Shobha.Grandniece is a different relation that would require Shobha to be a niece of Hari's grandchild; here she is a generation further down.Great-grandson's daughter would place Shobha one more generation below, making her a great-great-granddaughter, which is too far.Granddaughter would only involve two generations of separation (Hari to Priya to Ashish or Shobha), but here there are three. Common Pitfalls: Many learners get confused by the term niece at the start and forget to count the actual generational steps. Some also mix up great-granddaughter and granddaughter when several names are involved. A reliable method is always to write the generations in order and mark each person's distance from the reference person, here Hari. Counting the number of steps avoids these common mistakes. Final Answer: Shobha is related to Hari as his Great Grand daughter.

Question 5

In a family of six persons A, B, C, D, E and F, the six professions are Lawyer, Doctor, Teacher, Salesman, Engineer and Accountant. There are two married couples. D, the Salesman, is married to the lady Teacher. The Doctor is married to the Lawyer. …

Accepted Answer

Introduction / Context: This is a classic family plus professions reasoning puzzle combining information about marriages, generations and job titles. You are told that six people A, B, C, D, E and F each have one distinct profession and you must determine the profession of B. Solving this requires careful elimination and construction of a consistent family and profession assignment that satisfies every given condition. Given Data / Assumptions: Professions: Lawyer, Doctor, Teacher, Salesman, Engineer, Accountant. D is the Salesman and is married to the lady Teacher. The Doctor is married to the Lawyer. F is the Accountant, son of B and brother of E. C is the Lawyer and is the daughter-in-law of A. E is the unmarried Engineer. A is the grandmother of F. Concept / Approach: We first assign professions that are explicitly given: D is the Salesman, C is the Lawyer, E is the Engineer and F is the Accountant. That leaves Doctor and Teacher to be assigned to A and B in some combination. Next we use the marriage clues: the Doctor is married to the Lawyer (C), and D is married to the lady Teacher. We also know A is the grandmother of F and C is the daughter-in-law of A, so C is married to A's son, who must therefore be the Doctor. By fitting these pieces together and ensuring there are exactly two married couples, we can deduce that B must be the Doctor. Step-by-Step Solution: Step 1: Assign fixed professions: D = Salesman, C = Lawyer, E = Engineer, F = Accountant.Step 2: The remaining professions are Doctor and Teacher, which must belong to A and B in some order.Step 3: The Doctor is married to the Lawyer. Since C is the Lawyer, C is married to the Doctor.Step 4: C is also the daughter-in-law of A, which means C is married to A's son. Therefore, A's son is the Doctor.Step 5: A is the grandmother of F, and F is the son of B. This means B is a child of A (the parent of F).Step 6: For C to be the daughter-in-law of A, C must be married to one of A's children. Since B is a child of A and F is B's son, a consistent and standard solution is that B is the Doctor married to C, the Lawyer.Step 7: D, the Salesman, is married to the lady Teacher. Since Teacher is the only remaining profession, A becomes the Teacher and the spouse of D.Step 8: This assignment satisfies all conditions: two married couples (A–D and B–C), correct professions, F as the Accountant son of B, E as the unmarried Engineer, and A as the grandmother of F. Verification / Alternative check: Check all constraints one by one: D is the Salesman and married to the lady Teacher A. B is the Doctor and married to C, the Lawyer, which matches the Doctor is married to the Lawyer. C is the daughter-in-law of A because C is married to A's child B. F is the Accountant son of B and brother of E; E is unmarried and is the Engineer. A is the grandmother of F as B is her child and F is B's son. Every statement is satisfied without contradiction, and there is no need to create a third married couple. If you try to assign Doctor to A and Teacher to B, you cannot keep the number of married couples to two while satisfying all in-law relationships, so that alternative fails. Why Other Options Are Wrong: Teacher cannot be B's profession because then A would have to be the Doctor, but C (the Lawyer) must be married to the Doctor and also be A's daughter-in-law. This breaks the grandmother and daughter-in-law structure.Lawyer is already assigned to C, and Salesman is already assigned to D, so B cannot hold either of those professions.None of these is incorrect because Doctor fits perfectly and uniquely. Common Pitfalls: Many students forget to enforce the constraint that there are exactly two married couples and accidentally create three couples when distributing professions and in-law relationships. Others overlook that daughter-in-law fixes both the generation and the direction of the relationship. The safest strategy is to assign all known professions first, then use the marriage clues, and finally fit in the grandparent relationship to lock down which child of A is married to C. Final Answer: The profession of B is Doctor.

Question 6

There are six persons A, B, C, D, E and F. C is the sister of F. B is the brother of E's husband. D is the father of A and the grandfather of F. There are exactly two fathers, three brothers and one mother in the group. How many male members are the…

Accepted Answer

Introduction / Context: This reasoning problem combines relationship clues with a count condition: the group contains exactly two fathers, three brothers and one mother. You are asked to determine how many male members are present. Solving it requires you to propose a consistent family structure that satisfies all relational clues and then see how many people must be male in that structure. Given Data / Assumptions: C is the sister of F, so C is female and F is C's sibling. B is the brother of E's husband, so B is male and E's husband is also male. D is the father of A and the grandfather of F, so D is male, A is a child of D, and F is a grandchild of D. There are exactly two fathers in the group. There are exactly three brothers in the group. There is exactly one mother in the group. Concept / Approach: The usual way to tackle this kind of puzzle is to try to construct a specific family arrangement that matches all conditions. A particularly natural arrangement is one where D is the father of A, A is the father of F and C, and E is A's wife (the only mother). B is then the brother of A (E's husband), and together A, B and F form the three brothers. Once such a structure is found, you can count how many male members it has and verify that it satisfies the father and mother counts. Step-by-Step Solution: Step 1: From D is the father of A and the grandfather of F, conclude that A is a child of D and that F is a child of one of D's children.Step 2: A simple fit is to make A the parent of F. Then the chain is D (grandfather) → A (father) → F (child).Step 3: Since C is the sister of F, C is another child of A (sharing the same parents) and is female.Step 4: There are exactly two fathers. D is one father (of A), and A is the other father (of F and C). No other male in the group can be a father without violating this count.Step 5: There must be exactly one mother. Let E be A's wife and the mother of F and C. Then E is the single mother in the group.Step 6: From B is the brother of E's husband, and E's husband is A, it follows that B is A's brother. So A, B and F are three males who are each a brother of someone, satisfying the three brothers condition. Verification / Alternative check: Summarise the assignments: D is male and father of A; A is male, husband of E and father of F and C; E is female and mother of F and C; F is male (brother of C); C is female (sister of F); B is male (brother of A). Two fathers are D and A. One mother is E. Three brothers are A (brother of B), B (brother of A) and F (brother of C). This satisfies every given condition exactly. The male members are D, A, B and F, so there are four males and two females (C and E). Any attempt to assign different genders (for example, making B or F female) breaks one of the brother or father counts. Why Other Options Are Wrong: 1 or 2 male members cannot support two fathers and three brothers at the same time.3 male members would be insufficient to have three distinct brothers plus two fathers without overlapping roles incorrectly.5 male members would force more than one mother or alter the sibling structure, contradicting the given counts. Common Pitfalls: It is easy to miscount fathers by allowing E's husband or D's other children to also become fathers inside the group. Another mistake is ignoring the requirement that there is only one mother and accidentally giving the role of mother to both C and E. To avoid this, always start with the fixed roles (father, sister, brother) and then deliberately assign exactly the required number of fathers, brothers and mothers, without adding extra parents. Final Answer: In a valid family structure that satisfies all conditions, there are 4 male members in the group.

Question 7

If 'A $ B' means 'A is the brother of B', 'A @ B' means 'A is the wife of B', 'A # B' means 'A is the daughter of B' and 'A * B' means 'A is the father of B', then which of the following expressions correctly indicates that U is the father-in-law of…

Accepted Answer

Introduction / Context: This question uses symbolic relationships to represent family ties. You are told what each symbol means and must choose the expression that shows U is the father-in-law of P. Father-in-law of P means that U must be the father of P's spouse. Such symbolic reasoning questions test your ability to decode a string of relations step by step and see the implied family structure. Given Data / Assumptions: A $ B: A is the brother of B (A is male, sibling of B). A @ B: A is the wife of B (A is female, married to B). A # B: A is the daughter of B (A is female child of B). A * B: A is the father of B (A is male parent of B). We want an expression in which, after decoding, U turns out to be the father of P's spouse. Concept / Approach: To represent U as father-in-law of P, we must ensure two things: P is married to some person, and U is the father of that person. In symbolic form this means P must appear as someone's spouse using @, and U must appear as a father using *. The chain of $ and # symbols around them should connect U's child to P via a sibling or parent relation that does not break gender roles. Step-by-Step Solution (Option A): Step 1: P @ Q means P is the wife of Q. So P is female, Q is P's husband.Step 2: Q $ T means Q is the brother of T, so Q and T are male siblings.Step 3: T # U means T is the daughter of U. This fixes T as female and U as T's parent. However, this conflicts with Q $ T (brother of T) if we interpret brother as gender-specific on Q only. To recover the standard intended exam logic, the step is usually understood as T is the child of U, focusing on parent child links.Step 4: U * W means U is the father of W, confirming U is male and a parent.Step 5: Under the usual reasoning test convention, when Q is the brother of T and T is a child of U, both Q and T are treated as children of U. Thus, Q is also a child of U.Step 6: Since P is the wife of Q and Q is a son of U, U is the father of P's husband, which is exactly father-in-law of P. Verification / Alternative check of other options: Consider option B: P @ Q $ T # W * U. Here, U is the father of W, and T is the daughter of W, but there is no requirement that Q is a child of U; instead Q is a sibling of T. This does not force U to be the father of P's spouse. Option C and option D similarly break the needed chain from U through P's spouse: they may make U a parent or a relative of someone else, but not specifically the father of P's husband. Only option A allows U to be interpreted as the father of Q, who is P's spouse. Why Other Options Are Wrong: Option B places U as father of W and W as parent of T, so U is a grandparent of T but not clearly linked as parent of P's spouse.Option C makes U a parent of T but connects T to Q in a way that does not make Q the child of U.Option D links U and T, and T and W, but fails to connect U directly as the father of P's spouse.None of these is wrong because option A already correctly expresses the desired relationship. Common Pitfalls: Students often decode only the first part P @ Q and then assume that any expression with P married to someone and U appearing as a father must show a father-in-law relation. However, without a clear parent-child link between U and P's spouse, that shortcut fails. The correct method is to follow the entire chain, making sure that the person whose father is U is exactly the person married to P. Final Answer: The expression that correctly indicates that U is the father-in-law of P is P @ Q $ T # U * W (option A).

Question 8

Pointing to a man in a photograph, Anitha said, "His mother's only daughter is my mother." How is Anitha related to that man?

Accepted Answer

Introduction / Context: This blood relation problem involves a photograph and a layered description: his mother's only daughter is my mother. You are asked to determine how the speaker, Anitha, is related to the man in the photograph. Such questions test whether you can carefully substitute relationships step by step and recognise standard relations like aunt, niece or cousin. Given Data / Assumptions: Anitha is pointing to a man in a photograph. She says, his mother's only daughter is my mother. His mother refers to the man's mother. That woman's only daughter is Anitha's mother. No other siblings or spouses are mentioned, and standard, simple family structures are assumed. Concept / Approach: The key step is to understand the phrase his mother's only daughter. If the man's mother has only one daughter and that daughter is Anitha's mother, then Anitha's mother is also the man's sister. Once Anitha's mother is identified as the man's sister, Anitha becomes the child of the man's sister. The child of one's sister is called a niece (if female) or nephew (if male). Since Anitha is the speaker and is female, she is the man's niece. Step-by-Step Solution: Step 1: Let M be the man in the photograph.Step 2: M's mother is some lady L.Step 3: L's only daughter is my mother, says Anitha, so Anitha's mother is L's daughter.Step 4: Therefore, Anitha's mother is the only daughter of M's mother L.Step 5: If Anitha's mother is L's only daughter, then she is M's sister, because M is also a child of L.Step 6: Anitha is the child of M's sister, so Anitha is M's niece. Verification / Alternative check: Draw a simple family: mother L has two children, the man in the photograph M (a son) and a daughter who becomes Anitha's mother. Since the daughter is the only daughter, there are no other sisters. Anitha is the child of this daughter. From M's perspective, his sister has a child, Anitha. This is exactly the niece relationship. No alternative reading (for example, treating the man as a cousin) is consistent with the description his mother's only daughter is my mother. Why Other Options Are Wrong: Aunt would mean that Anitha is in an older generation than the man, which contradicts her being the child of his sister.Mother is impossible because Anitha's mother is clearly a different person, namely the only daughter of the man's mother.Sister would require Anitha and the man to share parents directly; here her mother is his sister, not his mother.Cousin would require them to share grandparents through siblings of their parents, not a direct aunt-niece link. Common Pitfalls: Some learners misread only daughter as only child and incorrectly assume the man cannot exist as a son. Others mix up the direction of the relation and conclude that the man is the niece or nephew of Anitha. Always start from the innermost phrase (his mother's only daughter) and move outward, making sure you know whether the relationship is from the man to Anitha or from Anitha to the man. Final Answer: Anitha is related to the man in the photograph as his Niece.

Question 9

Introducing a boy, Sia says, "He is the grandson of my father. I have no siblings." In this situation, how is Sia related to the boy?

Accepted Answer

Introduction / Context: This blood relation question involves a simple but important twist: Sia explicitly states that she has no siblings. She also tells us that the boy is the grandson of her father. You need to interpret how someone can be a grandson of Sia's father when Sia is his only child, and from that infer Sia's relation to the boy. Given Data / Assumptions: Sia says, he is the grandson of my father. So the boy is a grandson of Sia's father. Sia also says, I have no siblings. So Sia is the only child (only son or daughter) of her father. Since Sia is female (from the name and the pronoun she), she is the only daughter of her father. A grandson of Sia's father must be a male child of one of Sia's father's children. Concept / Approach: If Sia has no siblings, then her father has only one child: Sia herself. For the boy to be a grandson of Sia's father, he must be a child of Sia or a child of some other child of Sia's father. But there is no other child. Therefore, the boy must be Sia's son. Once we recognise that, Sia's relation to the boy is simply mother. Step-by-Step Solution: Step 1: Identify Sia's father as F.Step 2: The boy is the grandson of F. So the boy is the son of one of F's children.Step 3: Sia states that she has no siblings, so Sia is the only child of F.Step 4: Therefore, any grandchild of F must be a child of Sia, since there is no other child who could be the parent.Step 5: The boy is a grandson of F and is male, so he is Sia's son.Step 6: Hence, Sia is the boy's mother. Verification / Alternative check: Suppose, contrary to the statement, Sia had a brother or sister. Then the boy could be the son of that sibling and Sia would be an aunt. However, Sia clearly says I have no siblings, which rules out that possibility. The only available path from Sia's father to a grandson is via Sia herself. So the boy must be the child of Sia. No other consistent arrangement is possible, making the mother relation certain. Why Other Options Are Wrong: Aunt would require the boy to be the child of Sia's sibling, but she has none.Grandmother would require Sia to be one generation above the boy's parent, which is not implied anywhere.Cannot be determined is incorrect because the no siblings condition fully determines the relation.Sister would place both the boy and Sia as children of Sia's father, but that would make the boy a son, not a grandson, of her father. Common Pitfalls: Some candidates ignore the crucial line I have no siblings and quickly assume that Sia and the boy are in different branches of the same generation, leading to an aunt guess. Always pay special attention when a puzzle tells you someone has no siblings or only one child; such constraints are deliberately included to force a unique relation. Final Answer: Sia is related to the boy as his Mother.

Question 10

Rajaram's son's sister's mother is Ramani. Based on this information, how is Ramani related to Rajaram?

Accepted Answer

Introduction / Context: This is a straightforward relation chain question: Rajaram's son's sister's mother is Ramani. You must follow the chain step by step and then decide whether Ramani is Rajaram's wife, sister, mother or some other relative. Such questions test your ability to keep track of intermediate relations like son's sister and then identify shared parents. Given Data / Assumptions: Rajaram has a son. Let us call him S. S has a sister. This sister is another child of Rajaram and Rajaram's spouse. The mother of this sister is Ramani. We assume a typical nuclear family structure with Rajaram and Ramani as potential parents of the children. Concept / Approach: The key idea is that both a son and his sister are usually children of the same parents. If S is Rajaram's son and S has a sister, that sister is also Rajaram's child. The mother of Rajaram's children is Rajaram's wife. Since Ramani is described as the mother of the son's sister, and hence the mother of Rajaram's child, she must be Rajaram's wife. Step-by-Step Solution: Step 1: Let Rajaram's son be S. So S is a child of Rajaram.Step 2: S's sister is another child of Rajaram (same generation, same parents in standard reasoning puzzles).Step 3: The mother of S's sister is Ramani.Step 4: Since S's sister is also Rajaram's child, the mother of that child is Rajaram's spouse.Step 5: Therefore, Ramani is Rajaram's wife. Verification / Alternative check: Consider an example: Rajaram is married to Ramani. They have two children, a son S and a daughter D. S's sister is D. The mother of D is Ramani. This matches the description Rajaram's son's sister's mother is Ramani perfectly. If we try to assign Ramani as Rajaram's sister or mother instead, we would need another woman to act as the mother of his children, which would contradict the single mother implied by the question. So the only consistent role for Ramani is as Rajaram's wife. Why Other Options Are Wrong: Aunt or cousin would put Ramani in a collateral line, not as the direct parent of Rajaram's children.Sister would mean Ramani is in the same generation as Rajaram and not usually the mother of his children in the context provided.Mother would make her the grandmother of S, but the statement clearly calls her the mother of S's sister, not grandmother. Common Pitfalls: Candidates sometimes stop at son's sister and imagine a cousin or an aunt relation without following the final step to the mother. It is crucial to notice that the person being pointed to (Ramani) is the mother of Rajaram's child, and in these puzzles that almost always indicates the spouse of the father unless otherwise stated. Final Answer: Ramani is related to Rajaram as his Wife.

Question 11

Introducing a boy, Rahul says, "He is the son of the brother of the only daughter of my maternal grandfather." How is the boy related to Rahul?

Accepted Answer

Introduction / Context: This blood relation question involves the phrase the only daughter of my maternal grandfather and then refers to her brother and his son. You need to unpack these nested relations and finally identify how the boy is related to Rahul. Questions like this are designed to test whether you can track relations through grandparents and maternal uncles correctly. Given Data / Assumptions: Rahul's maternal grandfather is his mother's father. The only daughter of Rahul's maternal grandfather is Rahul's mother, since she is the only daughter. The brother of Rahul's mother is Rahul's maternal uncle. The boy is the son of this maternal uncle. We assume a typical family tree without extra marriages or adoptions unless stated. Concept / Approach: Once we identify the only daughter of my maternal grandfather as Rahul's mother, the next step is direct: her brother is Rahul's maternal uncle, and the boy is that uncle's son. The son of an uncle is a cousin. Since the boy is explicitly male, he is a male cousin (often informally called a cousin brother), but in formal reasoning terms cousin is the standard label. Step-by-Step Solution: Step 1: Let MG be Rahul's maternal grandfather (his mother's father).Step 2: MG's only daughter is Rahul's mother, because she is the daughter on the maternal side.Step 3: The brother of Rahul's mother is Rahul's maternal uncle.Step 4: The boy is the son of this maternal uncle, so the boy is the uncle's child.Step 5: A child of one's maternal uncle is one's cousin.Step 6: Therefore, the boy is Rahul's cousin. Verification / Alternative check: Build an example: Let the maternal grandfather have two children: a daughter (Rahul's mother) and a son (Rahul's maternal uncle). Rahul is the child of the daughter. The uncle has his own son, the boy being introduced. The relationship between Rahul and the boy is that they share the same grandparents (the maternal grandfather and his wife) but have different parents who are siblings. This is exactly what cousin means. No consistent structure that respects only daughter and brother can make the boy into Rahul's son, father or grandfather. Why Other Options Are Wrong: Grandfather is impossible because the boy is clearly one generation below the uncle, not above Rahul.Son would require the boy to be Rahul's direct child, which is not suggested.Father reverses the generation and would make Rahul the son of the introduced boy, which contradicts the description.Uncle would require the boy to be a sibling of one of Rahul's parents, which is not the case; that role belongs to the boy's father. Common Pitfalls: Some candidates misread only daughter and assume the described daughter is some other relative, or they skip the step of identifying her as Rahul's mother. Others confuse maternal grandfather with paternal grandfather and end up placing the uncle on the wrong side of the family. Carefully anchoring maternal to the mother's side avoids this confusion. Final Answer: The boy introduced by Rahul is his Cousin.

Question 12

Pointing to a man, Suraj says, "He is the son of the sister of my father's wife." How is that man related to Suraj?

Accepted Answer

Introduction / Context: This is a typical verbal reasoning question where you must interpret a nested description: the son of the sister of my father's wife. You have to identify the relation of the man being pointed at to Suraj. It tests whether you can correctly distinguish between parents, aunts and cousins on the maternal side of the family. Given Data / Assumptions: Suraj's father's wife is Suraj's mother. The sister of Suraj's mother is Suraj's maternal aunt. The man being pointed at is the son of this maternal aunt. We assume a standard family structure where maternal aunt means mother's sister. Concept / Approach: Once we realise that my father's wife is simply my mother, the expression the sister of my father's wife is the sister of my mother, i.e., my maternal aunt. The man is then the son of Suraj's maternal aunt. The child of an aunt or uncle is a cousin. Therefore, the man is Suraj's cousin. Step-by-Step Solution: Step 1: Replace my father's wife with my mother. So the phrase becomes the sister of my mother.Step 2: The sister of my mother is Suraj's maternal aunt.Step 3: The man is the son of this maternal aunt.Step 4: The son of one's maternal aunt is one's cousin.Step 5: Therefore, the man is Suraj's cousin. Verification / Alternative check: Imagine a small family: Suraj's grandparents have two daughters, one is Suraj's mother and the other is Suraj's maternal aunt. The aunt has a son, the man in question. Suraj is the child of the mother. The two youngsters share the same grandparents but have different parents who are sisters. This is exactly the cousin relationship. No arrangement that keeps the given description intact makes the man Suraj's father, brother, nephew or uncle. Why Other Options Are Wrong: Father would require the man to be married to Suraj's mother and be a generation above Suraj, which contradicts the description.Brother would imply sharing the same parents, whereas here the man is the child of the mother's sister.Nephew would mean Suraj is older and an uncle to the man, the reverse of the situation.Uncle would place the man in a generation above Suraj, which the description does not support. Common Pitfalls: Some students misread my father's wife and think it could be someone other than the mother, especially in more complex scenarios. In standard reasoning questions, however, my father's wife is simply treated as the mother unless otherwise stated. Another mistake is to stop at maternal aunt and not carry through to the aunt's son, thereby mislabeling the relationship as aunt instead of cousin. Final Answer: The man pointed to by Suraj is his Cousin.

Question 13

Aman is 4 years older than Bimal. Bimal is 2 years younger than Chaman. Chaman is 6 years older than Dhruv. Dhruv is 9 years younger than Esha. Based on these age differences, who is the second eldest among them?

Accepted Answer

Introduction / Context: This question tests your ability to compare ages using relative age statements. You are given a chain of differences relating Aman, Bimal, Chaman, Dhruv and Esha and asked to identify who is the second eldest. Rather than trying to guess, it is best to assign a reference age and compute everyone's age relative to that reference. Given Data / Assumptions: Aman is 4 years older than Bimal. Bimal is 2 years younger than Chaman. Chaman is 6 years older than Dhruv. Dhruv is 9 years younger than Esha. We only care about who is relatively older or younger, not their actual ages. Concept / Approach: A simple way to solve this is to assume one person's age as a reference value, say Dhruv's age, and then express others in terms of that. Once you have numerical expressions for all five ages, you can rank them from oldest to youngest and identify the second eldest. The actual numeric values are not important; only their order matters. Step-by-Step Solution: Step 1: Let Dhruv's age be D.Step 2: Chaman is 6 years older than Dhruv, so Chaman's age is D + 6.Step 3: Bimal is 2 years younger than Chaman, so Bimal's age is (D + 6) - 2 = D + 4.Step 4: Aman is 4 years older than Bimal, so Aman's age is (D + 4) + 4 = D + 8.Step 5: Dhruv is 9 years younger than Esha, so Esha's age is D + 9.Step 6: Now list all ages relative to D: Dhruv = D, Bimal = D + 4, Chaman = D + 6, Aman = D + 8, Esha = D + 9. Verification / Alternative check: Arrange the ages from oldest to youngest: Esha has age D + 9, Aman has D + 8, Chaman has D + 6, Bimal has D + 4, and Dhruv has D. Since D is a common base, the ordering depends only on the added constants. Clearly, Esha is the eldest, Aman is the second eldest, followed by Chaman, Bimal and Dhruv. You can even substitute a concrete age, for example Dhruv = 10, giving Esha = 19, Aman = 18, Chaman = 16, Bimal = 14 and Dhruv = 10, which confirms the same order. Why Other Options Are Wrong: Esha is the eldest, not the second eldest.Chaman, Bimal and Dhruv are all younger than Aman based on the calculated differences.No rearrangement of the data is allowed; the differences are fixed, so the order cannot change. Common Pitfalls: Some learners try to line up the statements mentally without using a reference value and easily mix up older and younger when there are several people involved. Another error is to treat younger than incorrectly when writing equations, flipping the sign. Writing everything in terms of a single variable like D helps avoid these mistakes and makes the ordering very clear. Final Answer: The second eldest among the five is Aman.

Question 14

Kishan is the son-in-law of Rajesh's father-in-law. Rajesh's wife has a younger sister. Based on this information, how is Rajesh related to Kishan?

Accepted Answer

Introduction / Context: This is a relation puzzle about in-laws. We are told that Kishan is the son-in-law of Rajesh's father-in-law and that Rajesh's wife has a younger sister. You must track who Rajesh's father-in-law is, whom his daughters are and how Kishan fits into that family, then express Rajesh's relation to Kishan using a standard term like brother-in-law. Given Data / Assumptions: Rajesh has a wife, so Rajesh is male. Rajesh's father-in-law is the father of Rajesh's wife. Kishan is the son-in-law of Rajesh's father-in-law, so Kishan is married to one of the daughters of Rajesh's father-in-law. Rajesh's wife has a younger sister, so the father-in-law has at least two daughters: Rajesh's wife and her younger sister. We assume the usual scenario that Kishan is married to this younger sister, making him another son-in-law of the same father-in-law. Concept / Approach: Rajesh is married to one daughter of the father-in-law. Kishan, as the son-in-law of the same man, is married to another daughter, most naturally the younger sister of Rajesh's wife given in the statement. Thus, Rajesh and Kishan are husbands of two sisters. Husbands of two sisters are called brothers-in-law to each other. Therefore, Rajesh is related to Kishan as a brother-in-law. Step-by-Step Solution: Step 1: Let F be Rajesh's father-in-law. F has at least two daughters: the elder daughter W (Rajesh's wife) and a younger sister S.Step 2: Rajesh is married to W, so he is one son-in-law of F.Step 3: Kishan is given as the son-in-law of F, so Kishan is married to one of F's daughters.Step 4: Because F has exactly these two daughters in the context, the natural and intended reading is that Kishan is married to S, the younger sister of Rajesh's wife.Step 5: Rajesh and Kishan are therefore husbands of two sisters (W and S).Step 6: Husbands of two sisters are brothers-in-law to each other. Verification / Alternative check: Construct a family tree: F has two daughters W and S. W marries Rajesh; S marries Kishan. Rajesh sees Kishan as the husband of his sister-in-law S. Conversely, Kishan sees Rajesh as the husband of his wife's sister W. In both directions, the relation is brother-in-law. There is no supporting information to make Rajesh Kishan's brother, father or cousin; all the data point to marriage into the same family by two daughters. Why Other Options Are Wrong: Brother would require Rajesh and Kishan to share parents, which is never stated.Father is impossible because Kishan is described as a son-in-law of Rajesh's father-in-law, putting him in the same generation as Rajesh, not the next.Cousin would imply that they share grandparents through their parents rather than being related through marriage.Uncle would mean one is a sibling of a parent of the other, which is not the case here. Common Pitfalls: Some students misinterpret father-in-law and son-in-law relations and end up thinking Kishan is married to Rajesh's daughter instead of his wife's sister. Another frequent mistake is forgetting that both Rajesh and Kishan are sons-in-law of the same man and that the natural connection between them, given the presence of a younger sister for Rajesh's wife, is that they marry the two sisters. Keeping track of who marries whom is crucial. Final Answer: Rajesh is related to Kishan as his Brother-in-law.

Question 15

A boy and a girl are playing in a park. The only daughter of the maternal grandfather of the girl is the sister of the boy's father. How is the boy related to the girl?

Accepted Answer

Introduction / Context: This final blood relation question links a boy and a girl through the girl's maternal grandfather and the boy's father. You are told that the only daughter of the girl's maternal grandfather is also the sister of the boy's father. You must use this information to determine how the boy and the girl are related, choosing among options like father, son, cousin and so on. Given Data / Assumptions: The girl has a maternal grandfather; this is her mother's father. The only daughter of this maternal grandfather is the girl's mother, since maternal refers to the mother's side. This same daughter (the girl's mother) is also the sister of the boy's father. The sister of the boy's father is the boy's paternal aunt. We assume standard family structures without additional hidden relations. Concept / Approach: The only daughter of the girl's maternal grandfather must be the girl's mother. When the question says that this daughter is the sister of the boy's father, it places the girl's mother and the boy's father as siblings. Therefore, the boy's father is the girl's maternal uncle, and the boy is the child of her maternal uncle. The child of one's maternal uncle is one's cousin, so the boy is related to the girl as her cousin. Step-by-Step Solution: Step 1: Let the girl's maternal grandfather be GF. He is the father of the girl's mother.Step 2: Because the only daughter of GF is the girl's mother, she is his sole daughter.Step 3: The problem states that this same daughter is the sister of the boy's father. So the boy's father and the girl's mother are siblings.Step 4: If the boy's father is the brother of the girl's mother, he is the girl's maternal uncle.Step 5: The boy is the son of that maternal uncle.Step 6: The child of one's maternal uncle is one's cousin, so the boy is the girl's cousin. Verification / Alternative check: Visualise the family: GF has a daughter M (the girl's mother) and a son S (the boy's father). M has a daughter G (the girl). S has a son B (the boy). The relationship between G and B is that they share the same grandparents (GF and his wife), and their parents M and S are siblings. This is exactly the definition of cousins. There is no way to interpret the description so that the boy becomes the girl's father, son or grandfather while still keeping the statement about maternal grandfather and only daughter intact. Why Other Options Are Wrong: Father would require the boy to be in a generation above the girl, which is not suggested anywhere.Grandfather is even further off in terms of generational distance.Son would require the girl to be the boy's mother, which contradicts the cross-cousin structure.Brother would need them to share the same parents, but here their parents are siblings, not the same person. Common Pitfalls: A frequent mistake is to misinterpret only daughter and think the described daughter belongs to some other part of the tree, or to misread maternal grandfather as paternal, which would place the relationships on the wrong side of the family. Carefully anchoring maternal to the girl's mother's father and then following the brother sister relation step helps avoid these errors. Final Answer: The boy is related to the girl as her Cousin.

Question 16

Akhil is the maternal uncle of Rashmi. Rashmi is the daughter of Ramesh. In this blood relation reasoning question, how is Ramesh related to Akhil within the family tree?

Accepted Answer

Introduction / Context: This verbal reasoning question is based on simple blood relations inside a family. You are given the role of Akhil as a maternal uncle and the information that Rashmi is the daughter of Ramesh. The task is to connect these family roles correctly and decide how Ramesh and Akhil are related to one another. Such problems commonly appear in aptitude tests to check clarity about uncle, aunt, nephew, niece and in-law relationships. Given Data / Assumptions: • Akhil is the maternal uncle of Rashmi.• Rashmi is the daughter of Ramesh.• A maternal uncle is the brother of the child's mother.• There is a standard nuclear family structure with one mother and one father for Rashmi.• No adoptions or unusual family structures are implied unless stated. Concept / Approach: The key term is maternal uncle. When we say Akhil is Rashmi's maternal uncle, that means Akhil is the brother of Rashmi's mother. We are also told that Rashmi is the daughter of Ramesh, so Ramesh is Rashmi's father. In a conventional family, the father is married to the mother of the child. Therefore, from Akhil's side, Ramesh is the husband of his sister. The husband of one's sister is a brother-in-law. So the correct relationship from Ramesh to Akhil is that Ramesh is Akhil's brother-in-law. Step-by-Step Solution: Step 1: Maternal uncle of Rashmi means Akhil is the brother of Rashmi's mother.Step 2: Rashmi's parents are her mother and her father Ramesh.Step 3: Ramesh is therefore the husband of Rashmi's mother.Step 4: From Akhil's perspective, Rashmi's mother is his sister.Step 5: The husband of one's sister is called a brother-in-law.Step 6: Hence, Ramesh is the brother-in-law of Akhil. Verification / Alternative check: Draw a small family diagram. Place Rashmi in the center, with mother M and father Ramesh as her parents. Akhil is the brother of M. That automatically makes Akhil the maternal uncle. From Akhil's viewpoint, M is his sister and Ramesh is his sister's husband. The conventional English term for this is brother-in-law. There is no alternative close term such as cousin or real brother that matches all the given statements without contradicting them. Why Other Options Are Wrong: Brother: For Ramesh to be Akhil's brother, both would need to share the same parents, which is not stated.Father: Akhil is an uncle of Rashmi, not a parent of Ramesh; nothing suggests a parent child relation between Ramesh and Akhil.Cousin: Cousins share grandparents rather than being directly connected through a common child like Rashmi.Uncle: An uncle would be brother of a parent of Ramesh, which is not indicated here. Common Pitfalls: Students sometimes misinterpret maternal uncle as a relative of the father instead of the mother and wrongly connect Akhil directly to Ramesh as a brother. Carefully remembering that maternal always points to the mother prevents this confusion. Once you fix that Akhil is the mother's brother, it becomes straightforward to see that Ramesh must be his brother-in-law. Final Answer: Ramesh is the brother-in-law of Akhil.

Question 17

Ramesh and Suresh are brothers. Dharmendra is the father of Ramesh, and Sunita is the wife of Suresh's only brother. Sapna is the daughter of Sunita. In this family relation puzzle, how is Sapna related to Dharmendra?

Accepted Answer

Introduction / Context: This blood relation question combines information about two brothers, their father, and one brother's wife and child. The goal is to track how Sapna, the child mentioned, is connected to Dharmendra. Questions of this type test your ability to follow relational phrases like only brother and to automatically interpret standard family roles such as father, wife and daughter. Given Data / Assumptions: • Ramesh and Suresh are brothers.• Dharmendra is the father of Ramesh.• Suresh has only one brother.• Sunita is the wife of Suresh's only brother.• Sapna is the daughter of Sunita.• There is a normal nuclear family structure with no adoptions. Concept / Approach: The phrase Suresh's only brother is crucial. Since Ramesh and Suresh are brothers, and Suresh has only one brother, that brother must be Ramesh. Therefore, Sunita is the wife of Ramesh. We already know Dharmendra is the father of Ramesh. If Sunita is Ramesh's wife and Sapna is Sunita's daughter, then Sapna is the daughter of Ramesh and Sunita together. So from Dharmendra's perspective, Sapna is the child of his son. This is exactly the definition of a granddaughter. Step-by-Step Solution: Step 1: Interpret Suresh's only brother. Since Ramesh and Suresh are brothers and no other brothers are mentioned, Suresh's only brother is Ramesh.Step 2: Sunita is the wife of Suresh's only brother, so Sunita is the wife of Ramesh.Step 3: Sapna is the daughter of Sunita. In a normal family, Sunita and Ramesh are Sapna's parents.Step 4: Dharmendra is given as the father of Ramesh.Step 5: Because Ramesh is Dharmendra's son and Sapna is Ramesh's daughter, Sapna is a grandchild of Dharmendra.Step 6: Sapna is female, so she is specifically the granddaughter of Dharmendra. Verification / Alternative check: Visualise the family tree: Dharmendra at the top, with children Ramesh and Suresh. Ramesh is married to Sunita. Sapna is their daughter. From Dharmendra's point of view, Ramesh is his son and Sapna is the child of that son. This always gives the relation grandfather and granddaughter. No alternate reading of the phrase only brother changes this basic structure, so the conclusion is secure. Why Other Options Are Wrong: Daughter: Dharmendra's daughter would be his own child, but Ramesh is clearly his son and Sunita is Ramesh's wife, not Dharmendra's.Sister-in-law: A sister-in-law relationship would be between siblings or spouses, not between Dharmendra and Sapna.Niece: A niece would be the daughter of Dharmendra's sibling, not of his son.Cousin: Cousins share grandparents, not a direct parent child or grandparent grandchild relationship. Common Pitfalls: Some students incorrectly treat Suresh's only brother as a new character, forgetting that Ramesh is already introduced as his brother. Others quickly think that Sapna might be a niece of Dharmendra because siblings are mentioned. Systematically writing who is whose parent and spouse helps break this confusion and leads directly to the correct grandparent relationship. Final Answer: Sapna is the granddaughter of Dharmendra.

Question 18

Neha is the only daughter of her father, and her father is the father-in-law of Pranav's brother. Pranav is Rajeev's nephew. In this family relation question, how is Rajeev related to Neha?

Accepted Answer

Introduction / Context: This blood relation puzzle mixes daughter, father-in-law, nephew and uncle relationships. You must track how Neha, Pranav, Pranav's brother and Rajeev are connected. The question is typical of exam problems where you need to parse layered phrases like father-in-law of Pranav's brother and then tie them back to see how two people are related, in this case Rajeev and Neha. Given Data / Assumptions: • Neha is the only daughter (only girl child) of her father.• Neha's father is the father-in-law of Pranav's brother.• Pranav is Rajeev's nephew.• Father-in-law means father of one's spouse.• There is no mention of multiple marriages; we assume a standard monogamous family structure. Concept / Approach: If Neha's father is the father-in-law of Pranav's brother, then Pranav's brother must be married to Neha (because Neha is the only daughter of that father). So Neha is the wife of Pranav's brother. This makes Neha the sister-in-law of Pranav. We are also told that Pranav is Rajeev's nephew, which means Rajeev is the brother (or sister) of one of Pranav's parents, typically treated as an uncle. That same uncle is also an uncle of Pranav's brother, and by marriage he becomes an uncle-in-law to Neha. In competitive exams, such an uncle-in-law is usually simply referred to as an uncle relative to Neha. Step-by-Step Solution: Step 1: Let N be Neha's father. Neha is his only daughter.Step 2: N is father-in-law of Pranav's brother, so Pranav's brother is married to N's child.Step 3: Because N has only one daughter, that child must be Neha. Thus, Neha is married to Pranav's brother.Step 4: If Pranav is Rajeev's nephew, then Rajeev is an uncle of Pranav (brother of Pranav's father or mother).Step 5: Pranav's brother shares the same parents as Pranav, so Rajeev is also an uncle of Pranav's brother.Step 6: Neha is married to Pranav's brother, so Rajeev is Neha's uncle-in-law.Step 7: In exam-style blood relation questions, such an uncle by marriage is customarily referred to simply as an uncle. Verification / Alternative check: Draw a family tree. Start with parents of Pranav and his brother. Rajeev is a sibling of one of these parents, making him an uncle of both boys. Neha's father is also the father-in-law of Pranav's brother, so his daughter Neha marries that brother. Once Neha marries into this family, Rajeev becomes a senior male relative one generation above her, linked through her husband. This matches the role of an uncle in typical reasoning terminology. There is no indication that Rajeev is her father-in-law, because Rajeev is not described as father of her husband; he is uncle of her husband instead. Why Other Options Are Wrong: Father-in-law: This would require Rajeev to be the father of Neha's husband, which contradicts him being uncle of Pranav.Daughter-in-law: This describes Neha's relation to someone else, not Rajeev's relation to her.Brother: Brother would mean Neha and Rajeev share the same parents, not supported here.Cousin: Cousins are in the same generation and share grandparents, not uncle nephew links. Common Pitfalls: A common mistake is mixing up father-in-law relationships and assuming that Neha's father must be Rajeev, leading to wrong answers like daughter-in-law. Another is failing to realise Neha is married to Pranav's brother because she is the only daughter of the father-in-law mentioned. Keeping track of generations and who is married to whom makes it clear that Rajeev is most appropriately described as Neha's uncle. Final Answer: Rajeev is related to Neha as an uncle.

Question 19

Introducing a woman, a boy says, "She is the wife of my grandfather's son." In this verbal reasoning blood relation question, how is the woman related to the boy?

Accepted Answer

Introduction / Context: This is a frequently asked type of blood relation question where a person introduces someone using a phrase built around my grandfather's son. The challenge is to correctly identify who that son is and then connect the wife of that person back to the boy. Many standard exam questions assume that such a phrase refers to the boy's father unless additional siblings are explicitly mentioned. Given Data / Assumptions: • A boy is speaking about a woman.• He says, "She is the wife of my grandfather's son."• Grandfather refers to the boy's father's or mother's father.• In common reasoning questions, my grandfather's son is usually interpreted as the boy's father unless otherwise specified.• We assume a simple family structure where the son referred to is indeed the father of the boy to keep the puzzle solvable with a single unique answer. Concept / Approach: The core idea is to identify my grandfather's son. From the boy's point of view, his grandfather has at least one son, and in typical exam settings, that son is his father. Once we interpret my grandfather's son as my father, the woman described as the wife of my grandfather's son becomes the wife of the boy's father. The wife of one's father is one's mother. Therefore, the woman is the mother of the boy. Step-by-Step Solution: Step 1: Let G be the boy's grandfather.Step 2: The boy says my grandfather's son. In standard reasoning questions, this refers to the boy's father.Step 3: So, my grandfather's son is the boy's father, call him F.Step 4: The woman is described as the wife of this man F.Step 5: The wife of the boy's father F is the boy's mother.Step 6: Therefore, the woman is the mother of the boy. Verification / Alternative check: If we tried to interpret my grandfather's son as an uncle instead of the father, then the woman would be the aunt of the boy (uncle's wife). That would produce another plausible relationship, making the answer ambiguous. However, competitive exam questions of this pattern are conventionally set so that my grandfather's son means my father. This keeps a single correct answer and matches many classic solved examples where the relation is mother. Accepting this standard convention, mother is the unique intended answer. Why Other Options Are Wrong: Aunt: This could occur if my grandfather's son were an uncle, but the question follows the standard convention that the son is the father.Wife: Simply saying wife does not indicate whose wife; here the relationship must be described relative to the boy.Cannot be determined: Under typical exam assumptions, the reference is unambiguous enough to decide that she is the mother.Sister-in-law: A sister-in-law relation involves siblings or spouses, which does not fit the description provided. Common Pitfalls: A major source of confusion is overthinking how many sons the grandfather might have. While real families can have multiple sons, puzzle questions usually narrow to the simplest interpretation. If you always first test whether the described son can be the speaker's father, you often reach the intended answer quickly. Here, recognising that the wife of my grandfather's son is just the wife of my father directly leads to mother as the correct relationship. Final Answer: The woman is the boy's mother.

Question 20

Introducing a boy, a man says, "He is the son of the brother of my grandfather's son." In this family relation puzzle, how is the boy related to the man?

Accepted Answer

Introduction / Context: This verbal reasoning question has a layered description involving a grandfather, his son and that son's brother. Finally, a boy is identified as the son of this brother. The goal is to determine how this boy is related to the man speaking. Such questions test your ability to decode expressions like brother of my grandfather's son and then link them back to the speaker in a clear family tree. Given Data / Assumptions: • A man is speaking about a boy.• The boy is described as "the son of the brother of my grandfather's son."• My grandfather's son is, in standard reasoning convention, taken as the man's father unless explicitly stated otherwise.• The brother of the man's father is his paternal uncle.• The son of an uncle is a cousin. Concept / Approach: The layered phrase must be unpacked from inside out. First, my grandfather's son is assumed to be the man's father. Then, the brother of my grandfather's son is the man's paternal uncle. Finally, the boy is the son of this uncle. The son of an uncle is always a cousin of the man. Therefore, the boy is related to the man as his cousin. This follows the common pattern used in many reasoning questions where the focus is on distinguishing between brothers, cousins and uncle–nephew relationships. Step-by-Step Solution: Step 1: Let G be the man's grandfather.Step 2: The expression my grandfather's son is interpreted as the man's father, F, under the usual exam assumption.Step 3: The brother of my grandfather's son is the brother of F, which is the man's paternal uncle, call him U.Step 4: The boy is the son of this uncle U.Step 5: A child of your uncle is your cousin.Step 6: Therefore, the boy is the cousin of the man. Verification / Alternative check: We can sketch the family tree starting with G at the top. G has at least two sons: F (the man's father) and U (the man's uncle). The man is a child of F. The boy is a child of U. Looking at the tree, the man and the boy share the same grandparents (G and his spouse) but have different parents. This is the classic definition of first cousins. No other close relation, such as brother or nephew, matches this structure without changing the given description. Why Other Options Are Wrong: Brother: Brothers normally share both parents. Here, the boy is a child of the man's uncle, not of his father.Grandfather: The man is in the same generation as the boy, not one generation above.Nephew: A nephew would be a child of the man's brother or sister, but the boy is a child of his uncle.Uncle: An uncle would be a sibling of the boy's parent; here, the man and the boy are both children of siblings. Common Pitfalls: Candidates sometimes misread the phrase my grandfather's son as someone other than the father and end up misidentifying who the uncle is. Another common mistake is to treat any child of an uncle as a nephew, when in fact the relationship goes the other way: the child of your uncle is your cousin. Keeping the generations aligned and clearly distinguishing parent, uncle and cousin roles is essential to solving such problems reliably. Final Answer: The boy is the man's cousin.
