Question 1

Data sufficiency — Who is the uncle of L? Statements: A. P, brother of M, is father of L; M is father of S. B. R is father of L's cousin. Decide which statements are sufficient to determine the uncle of L.

Accepted Answer

Introduction / Context: The task is to identify L’s uncle using data sufficiency. We must determine whether each statement alone (or together) pins down a unique answer. Given Data / Assumptions: A: P and M are brothers; P is father of L; M is father of S. B: R is father of L’s cousin (ambiguous without further ties). Concept / Approach: An uncle is a brother of a parent (or spouse thereof, depending on convention). From A, we know P is L’s father and that P’s brother is M, i.e., M is paternal uncle of L. Step-by-Step Solution: 1) From A: Since P (male) and M (male) are brothers, and P is L’s father, M is L’s paternal uncle by definition.2) From B: Knowing only that R is father of L’s cousin does not reveal whose sibling R is, nor fix which side of the family produces the cousin. B is insufficient. Verification / Alternative check: Under A, there is no ambiguity: the uncle is M. Under B, R could be any cousin’s father through various family branches; multiple possibilities exist. Why Other Options Are Wrong: B alone: Too vague to identify a unique uncle. Either A or B: False, as B fails. Both not sufficient: False, A is already sufficient. A and B together: Redundant since A alone suffices. Common Pitfalls: Mistaking any cousin’s parent as automatically an uncle; overlooking that “cousin” may arise from either parent’s siblings. Final Answer: A alone is sufficient.

Question 2

Data sufficiency — How is P related to J? Statements: A. M is the brother of P and T is the sister of P. B. P's mother is married to J's husband, who has one son and two daughters. Identify which statements suffice to determine P's relation to J.

Accepted Answer

Introduction / Context: We are to fix the relationship of P to J using minimal information. As a data-sufficiency item, we focus on whether the statements force a unique relation without overbuilding the tree. Given Data / Assumptions: A: M is P’s brother; T is P’s sister (sibling set info; no mention of J). B: P’s mother is married to J’s husband, who has one son and two daughters. Concept / Approach: If “P’s mother is married to J’s husband” under standard monogamous interpretation, the only coherent reading is that J is P’s mother (J’s husband is P’s father, married to P’s mother). Thus P is the child of J. Step-by-Step Solution: 1) From B: J’s husband and P’s mother are a married pair, which identifies J as P’s mother.2) Therefore, P is related to J as child (gender of P not required).3) From A: Only sibling composition is known; no link to J, hence insufficient by itself. Verification / Alternative check: Any attempt to interpret B otherwise leads to polygamy or contradiction. The cleanest, standard reading is J = P’s mother. Why Other Options Are Wrong: A alone: No J mentioned; cannot conclude. Either A or B: False, because A fails. Both not sufficient: False, B alone suffices. A and B together: Redundant; B already suffices. Common Pitfalls: Overcomplicating the phrase “P’s mother is married to J’s husband”; the intended inference is straightforward in standard family-logic settings. Final Answer: B alone is sufficient (P is J’s child).

Question 3

A is B's sister. C is B's mother. D is C's father. E is D's mother. How is A related to D?

Accepted Answer

Introduction / Context: This is a standard blood-relation reasoning question where multiple generational links are described step by step. The task is to trace these relationships carefully and then identify how one person is related to another. Such questions are common in aptitude tests because they measure the ability to organize hierarchical family information in a logical way. Given Data / Assumptions: A is B's sister, so A and B are siblings and A is female. C is B's mother, meaning C is a parent of B and therefore also a parent of A. D is C's father, so D is the grandfather of both A and B. E is D's mother, placing E one generation above D, but E is not directly needed to answer the question. We assume a typical family structure with no unusual relationships like adoption unless explicitly stated. Concept / Approach: The key is to map each person onto a family tree and mark their generation: great-grandparents, grandparents, parents, children and grandchildren. Once we know the positions of A and D in this tree, we can easily describe their relationship using standard kinship terms such as father, mother, grandmother, granddaughter and so on. Step-by-Step Solution: Step 1: From “A is B's sister”, we know A and B share the same parents and A is female. Step 2: From “C is B's mother”, C is a parent of B. Because A is B's sister, C is also A's mother. Step 3: From “D is C's father”, D is the parent of C. Step 4: Since C is A's mother and D is C's father, D is one generation above C and two generations above A. Step 5: Therefore, D is A's grandfather, and conversely A is D's granddaughter. Verification / Alternative check: We can sketch a quick family tree. At the top is E, whose child is D. D's child is C. C's children are A and B. In this tree, D sits two levels above A, exactly the grandparent level. A is specifically female, as stated, so she must be a granddaughter rather than a grandson. This cross-check confirms our conclusion. Why Other Options Are Wrong: “Grandfather” and “Grandmother” describe how D or E might be related to someone else, but the question asks how A is related to D. A is not a grandparent of D. “Daughter” would mean A is the direct child of D, but there is a generation in between (C) so this is incorrect. Common Pitfalls: One common error is to read the relationships in the wrong direction, for example interpreting “D is C's father” as C being D's father. Another mistake is losing track of how many generations down the chain you have moved. Explicitly writing each step helps avoid confusion, especially in longer chains involving grandparents and great-grandparents. Final Answer: A is related to D as his granddaughter.

Question 4

Pointing to a person, a man said to a woman, "His mother is the only daughter of your father." How is the woman related to that person?

Accepted Answer

Introduction / Context: This blood-relation question presents a short dialogue and asks you to infer the relationship between a woman and a person in front of her. Such problems rely on translating the spoken description into a simple family relationship diagram. The key idea here is the phrase “only daughter of your father”. Given Data / Assumptions: A man is speaking to a woman while pointing to a person. The man says: “His mother is the only daughter of your father.” The pronoun “his” refers to the person being pointed at. We are asked: How is the woman related to that person? We assume the father mentioned is the woman's biological father and that “only daughter” means he has exactly one daughter. Concept / Approach: The central phrase is “only daughter of your father”. Since the man is addressing the woman, her father's only daughter must be the woman herself, because if there were any other daughters, the term “only” would not be correct. Once we identify the mother of the person in the photograph as the woman herself, it becomes straightforward to see what relationship she has with him. Step-by-Step Solution: Step 1: Interpret “your father” as the father of the woman being addressed. Step 2: The expression “the only daughter of your father” means that the woman is the single female child of her father. Therefore, the only daughter is the woman herself. Step 3: The man says, “His mother is the only daughter of your father.” So the mother of the person being pointed to is the woman. Step 4: If the woman is the person's mother, the person in the photograph must be her son. Step 5: Therefore, the woman is the mother of that person. Verification / Alternative check: We can restate the sentence by substituting “the woman” for “only daughter of your father”: “His mother is the woman.” This clearly shows that the woman occupies the role of mother for the person referenced. No other interpretation is consistent with the word “only” in the original statement. Why Other Options Are Wrong: “Aunt” would apply if the woman was a sister of the person's father or mother, but the statement clearly says she is the mother herself. “Wife” would describe her relationship to another adult, not to the person being pointed at. “Daughter” reverses the relationship, suggesting that the woman is the child of the person in the picture, which contradicts the information given. Common Pitfalls: Examinees sometimes confuse whose father or mother is being referred to and mis-assign the “only daughter” label. Keeping track of pronouns (“your”, “his”) and explicitly replacing them with the correct names in a rough diagram helps avoid such logical slips. Final Answer: The woman is related to the person as his mother.

Question 5

A girl introduced a boy as "the son of the daughter of the father of my uncle." How is the boy related to the girl?

Accepted Answer

Introduction / Context: This blood-relation puzzle has a layered description involving “the son of the daughter of the father of my uncle”. It is a classic examination question designed to test whether you can carefully unpack nested relationships and correctly identify the final familial connection. The pronoun “my” refers to the girl who is introducing the boy. Given Data / Assumptions: The speaker is a girl. She describes a boy as: “the son of the daughter of the father of my uncle.” We assume a typical family tree where “uncle” means the brother of one of her parents. We are asked how this boy is related to the girl. Standard exam convention usually assumes straightforward relationships (no step-siblings or adoptions) unless stated. Concept / Approach: To solve nested relationship phrases, it is helpful to decode them from inside out. We start by identifying the “father of my uncle”, then his “daughter”, and finally “the son” of that daughter. Once we turn each phrase into a familiar family role (such as grandfather, mother, etc.), the final relationship usually becomes clear. We also follow the common exam assumption that all siblings mentioned here belong to the same nuclear family. Step-by-Step Solution: Step 1: Identify “my uncle”. For a girl, an uncle is typically the brother of her father or the brother of her mother. Step 2: The “father of my uncle” is the same as the girl's grandfather (on whichever side this uncle belongs to). Step 3: The “daughter of the father of my uncle” means a daughter of this grandfather. Under the usual exam assumption, this includes the girl's mother or the girl's aunt. In many standard solutions, this daughter is taken to be the girl's mother. Step 4: The “son of the daughter of the father of my uncle” is then the son of that daughter, that is, the son of the girl's mother. Step 5: The son of the girl's mother is the girl's brother (they share both parents). Verification / Alternative check: We can rewrite the full expression using the more familiar labels identified. The boy is introduced as “the son of my mother”. That is exactly what we call a brother. Because the speaker is a girl, her mother's son is her brother, not herself. Hence the boy must be her brother. Why Other Options Are Wrong: “Son” would suggest that the boy is the girl's own child, which is not supported by any part of the chain. “Uncle” would apply if the boy were a brother of one of her parents, but the chain clearly makes him a descendant of her mother, not a sibling of her mother or father. “Son-in-law” is irrelevant, as no information about marriage of the girl's children is given. Common Pitfalls: Candidates often get lost in the multiple “of the” phrases and misread the generational direction. A good strategy is to replace each step with a simple label (grandfather, mother, brother) on a rough diagram before going to the next step. This structured approach helps prevent confusion in nested expressions. Final Answer: The boy is the girl's brother.

Question 6

Pointing to a lady, a girl said, "She is the daughter-in-law of the grandmother of my father's only son." How is the lady related to the girl?

Accepted Answer

Introduction / Context: This question tests the ability to decode a slightly long description of family relations and identify how a particular lady is related to the girl who is speaking. The phrase “daughter-in-law of the grandmother of my father's only son” must be interpreted step by step to avoid confusion. Such questions are quite common in bank and SSC aptitude exams. Given Data / Assumptions: The speaker is a girl. She says about a lady: “She is the daughter-in-law of the grandmother of my father's only son.” “My father's only son” refers to the single male child of her father. We assume standard, straightforward family relationships without step-relations unless explicitly mentioned. Concept / Approach: The description involves three levels: the girl and her father, her father's only son, and that boy's grandmother. Then we look at who is the daughter-in-law of that grandmother. The main trick is to correctly understand who “my father's only son” is, and whose grandmother is being referred to. After that, identifying the daughter-in-law of that grandmother reveals whether the lady is the girl's mother or some other female relative. Step-by-Step Solution: Step 1: Interpret “my father's only son”. The speaker is a girl, so her father's only son must be her brother (if she has one) and there is exactly one such boy. Step 2: The “grandmother of my father's only son” is the grandmother of this brother. But that same grandmother is also the girl's grandmother, because they share the same father. Step 3: So, “the grandmother of my father's only son” is simply the girl's grandmother (most likely the father's mother in a typical puzzle). Step 4: The lady in question is described as the “daughter-in-law” of this grandmother. A daughter-in-law of the girl's grandmother will be the wife of one of the grandmother's sons. Step 5: One such son is the girl's father. His wife is the girl's mother, who is a daughter-in-law of the girl's grandmother. Under usual exam assumptions, this is the intended relationship for the lady being pointed at. Verification / Alternative check: We can substitute labels: grandmother = G, her son = F (the girl's father), and F's wife = M (the girl's mother). M is a daughter-in-law of G. The girl is a child of F and M. The described lady therefore matches the position of the girl's mother. Any other daughter-in-law of G, such as an aunt, is not singled out in the puzzle, and typical solutions treat the direct parent-child link as the intended one. Why Other Options Are Wrong: “Sister-in-law” would be the wife of the girl's brother or the sister of her husband, not the daughter-in-law of her grandmother. “Aunt” could be another daughter-in-law of the grandmother, but the question structure in standard reasoning books usually takes this configuration as describing the girl's mother, not her aunt. “Can't be determined” is incorrect at exam level because the intended standard assumption points to the direct relationship of mother and daughter. Common Pitfalls: A common mistake is to start combining too many hypothetical relatives (multiple sons of the grandmother) and conclude that the answer is indeterminate. In typical test settings, unless multiple possibilities are explicitly highlighted, puzzles like this are meant to be solved using the most direct and obvious family links. Final Answer: The lady is related to the girl as her mother.

Question 7

P is the brother of Q and R. S is R's mother. T is P's father. Which of the following statements cannot be definitely true?

Accepted Answer

Introduction / Context: This reasoning question asks you to identify which one of the given statements cannot be definitely concluded from the information provided. It is not about which statement is impossible, but rather which statement is not guaranteed to be true in every valid family arrangement consistent with the given clues. Understanding the difference between “possible” and “definitely true” is the key here. Given Data / Assumptions: P is the brother of Q and R, so P, Q and R are siblings and P is male. S is R's mother. T is P's father. Standard exam convention assumes siblings share the same parents unless stated otherwise, so P, Q and R typically have the same mother and father. We must decide which of the given four statements cannot be asserted as definitely true. Concept / Approach: First, we interpret “brother of Q and R” in the usual exam sense: P, Q and R are children of the same parents S (mother) and T (father). Then we check each option to see whether it must follow in all such cases or whether, in at least one consistent interpretation, it might fail. The subtle point is about the gender of Q, which is not specified. Step-by-Step Solution: Step 1: If S is R's mother and P is the brother of R, then in standard reasoning puzzles S is also the mother of P and Q. Step 2: Similarly, if T is P's father and P is the brother of Q and R, T is also taken as the father of Q and R. Step 3: Under these assumptions, T is Q's father. So the statement “T is Q's father” must be true. Step 4: Since S is the mother of R and siblings typically share parents, S is also P's mother. So “S is P's mother” is definitely true as well. Step 5: P is explicitly stated to be male (“brother”), and S is his mother, so “P is S's son” is also definitely true. Step 6: However, the statement “Q is T's son” assumes that Q is male. The question does not specify Q's gender; Q could be either a son or a daughter of T. Step 7: Because we cannot be certain that Q is male, we cannot say with certainty that “Q is T's son” is true. Q might instead be T's daughter. Verification / Alternative check: Consider two possible family configurations consistent with the clues. In one, Q is male; then the statement “Q is T's son” is true. In another, Q is female; then the statement becomes false and the correct description would be “Q is T's daughter”. Since both configurations are consistent with the question stem, the statement about Q being T's son is not definitely true. Why Other Options Are Wrong: Each of the other three options follows directly from the standard assumption that P, Q and R are full siblings with common parents S and T. There is no scenario under that convention in which T is not Q's father, S is not P's mother, or P is not S's son. Common Pitfalls: Many students mistakenly look for logical impossibility instead of “not definitely true”. Others overlook unspecified gender and assume that every child mentioned without a label is male. Always pay close attention to which individuals have clearly stated genders (like “brother”) and which do not. Final Answer: The statement that cannot be definitely true is “Q is T's son.”

Question 8

There are six persons A, B, C, D, E and F in a family. 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. Who is the mother?

Accepted Answer

Introduction / Context: This is a more involved blood-relation puzzle combining information about genders, parent–child relationships and counts of roles (fathers, brothers and a mother) within a six-person family. The goal is to identify the person who must be the mother based on all clues. Such questions are designed to test systematic reasoning rather than quick guessing. Given Data / Assumptions: Family members: A, B, C, D, E and F. C is the sister of F, so C is female and F is her sibling. B is the brother of E's husband, so B is male and is a brother-in-law of E. D is the father of A and the grandfather of F, so D is male and one generation above A and two above F. There are exactly two fathers in the group. There are exactly three brothers in the group. There is exactly one mother in the group. We assume standard family structure without adoptions or remarriages unless required. Concept / Approach: First we place D as a father and grandfather, then deduce who F's parent must be. From that we infer the second father and locate the single mother. We also check the count of “brothers” (males who are brothers to someone) to ensure consistency. The final configuration must satisfy all role counts and the given relationships simultaneously. Step-by-Step Solution: Step 1: D is the father of A and the grandfather of F. Therefore, A is a child of D, and F is a grandchild of D through A. So A must be a parent of F. Step 2: Since D is already one of the two fathers, A, as a parent of F, is likely the second father (so A is male). This satisfies the “two fathers” condition with D and A. Step 3: C is the sister of F, so C and F are children of A and some other parent. That other parent must be the only mother in the group. Step 4: B is the brother of E's husband. The most natural way to satisfy all relations is to take E as the spouse of A. Then B is A's brother. Step 5: If E is A's wife, and A is the father of F and C, E is their mother. So E is the unique mother in the family, fulfilling the “one mother” condition. Step 6: Now count the brothers. A and B are brothers to each other (both sons of D), and if F is male, he is a brother to C. That gives three brothers: A, B and F, matching the condition “three brothers”. Verification / Alternative check: Let us summarise the consistent family tree: D is the father of A and B. A (male) is married to E (female). A and E are the parents of C and F, where C is a sister and F is a brother. In this arrangement, fathers: D and A (two fathers); brothers: A, B and F (three brothers); mother: E (one mother). All given relational statements are satisfied and all counts match perfectly. Why Other Options Are Wrong: A cannot be the mother because A is a son of D and fits better as F's father, giving us the required two fathers. B is a brother of E's husband and therefore male, but there is no indication that B has any child; he cannot be the unique mother. C is specifically stated to be a sister of F, i.e., female, but she is in the children's generation, not a parent. Common Pitfalls: Test-takers often ignore the role counts and focus only on direct relational clues, which can lead to multiple seemingly possible arrangements. The constraints “two fathers, three brothers and a mother” are crucial and are what uniquely force E to be the mother. Always use count-based constraints carefully in such puzzles. Final Answer: The mother in the family is E.

Question 9

Pointing to a lady, a man said, "The son of her only brother is the brother of my wife." How is the lady related to the man?

Accepted Answer

Introduction / Context: This blood-relation question links the family of a lady to the wife of the man who is speaking. The challenge is to interpret the phrase “the son of her only brother is the brother of my wife” and then deduce how the lady must be connected to the man. It especially tests understanding of in-law relationships like “sister of father-in-law”. Given Data / Assumptions: A man is speaking and pointing at a lady. He says: “The son of her only brother is the brother of my wife.” “Her only brother” means the lady has exactly one brother. The son of that brother is a male child (nephew of the lady). That son is also described as “the brother of my wife”. We assume standard family structure without adoptions unless mentioned. Concept / Approach: We move step by step: first identify the lady's only brother, then his son, and then connect that son to the man's wife. From there, we can locate where the lady fits with respect to the man's in-laws. Ultimately, we want a single kinship term describing how the lady and the man are related. Step-by-Step Solution: Step 1: Let L be the lady, B be her only brother, and S be B's son. Then S is the nephew of L (because he is her brother's son). Step 2: The man says S is “the brother of my wife”. Therefore, S and the man's wife share the same parents. Step 3: That implies B and his spouse are the parents of both S and the man's wife. So B is the father of the man's wife. Step 4: So B is the man's father-in-law, because B is the father of his wife. Step 5: The lady L is the sister of B (“her only brother”), so she is the sister of the man's father-in-law. Verification / Alternative check: We can restate: Lady L's brother B has two children: S and the man's wife W. S is W's brother, as the statement says. Because W is married to the man, B is W's father and thus the man's father-in-law. L, being B's sister, is therefore the sister of the man's father-in-law. This consistent family picture supports our conclusion. Why Other Options Are Wrong: “Mother's sister” would make the lady an aunt of the man by blood, but the chain here runs through the wife's family, not the man's mother. “Grandmother” is two generations above; nothing in the wording suggests the lady is a grandparent of anyone related to the man. “Mother-in-law” would require the lady to be the mother of the man's wife, but we have already identified her as the sister of the wife's father, not his wife. Common Pitfalls: Examinees often misread “brother of my wife” as referring to the man's brother, confusing the direction of the “of” phrase. Carefully track whose brother is being discussed and draw a small diagram if necessary. Also remember that in-law relationships are defined around one's spouse, not around oneself directly. Final Answer: The lady is the sister of the man's father-in-law.

Question 10

A woman introduces a man as "the son of the brother of my mother." How is the man related to the woman?

Accepted Answer

Introduction / Context: This blood-relation question involves a description of how a woman introduces a man and asks you to pinpoint the correct relationship. The core expression is “son of the brother of my mother”, which is a standard way of referring to a cousin. Decoding that phrase accurately is all that is required to answer the question. Given Data / Assumptions: The speaker is a woman. She introduces a man as “the son of the brother of my mother”. “My mother” refers to the speaker's mother. “The brother of my mother” is the speaker's maternal uncle. We assume standard family relationships with no extra complications. Concept / Approach: We can break the description into two steps: first identify who the brother of the speaker's mother is, then identify what relation his son has to the speaker. In normal family terminology, the children of one's maternal uncle are one's maternal cousins. Since the man being introduced is male, he is a male cousin of the woman. Step-by-Step Solution: Step 1: Take “my mother” as the woman's mother. Step 2: The “brother of my mother” is the woman's maternal uncle. Step 3: The man is described as “the son of the brother of my mother”, i.e., the son of the woman's maternal uncle. Step 4: A son of one's maternal uncle is a cousin (more precisely, a maternal male cousin). Step 5: Therefore, the man is the woman's cousin. Verification / Alternative check: We can express the phrase with more familiar labels: “He is the son of my maternal uncle.” Most people would immediately say this is a cousin. Since nothing in the question suggests a different or more distant relationship, this confirms the answer. Why Other Options Are Wrong: “Nephew” would mean the man is a son of the woman's sibling, but here he is a son of her uncle, not her brother or sister. “Son” would make the man a direct child of the woman, which is inconsistent with the given chain. “Uncle to grandson” is not even a standard single relationship term and clearly does not match the simple two-generation link described. Common Pitfalls: The main danger is mixing up “brother of my mother” with “mother of my brother”. Swapping the order of these words completely changes the relationship. Always read such expressions slowly and, if needed, substitute explicit names for each role to keep track of who is who. Final Answer: The man is the woman's cousin.

Question 11

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

Accepted Answer

Introduction / Context: This blood-relation puzzle combines marital relations, siblings and generational information to identify how one particular member, E, is related to another member, C. Questions of this type test whether you can build a correct family tree from multiple interconnected clues, including a widowed grandparent and a daughter-in-law. Given Data / Assumptions: A and B form a married couple, with A being male. C is the brother of A, so C is male and in the same generation as A. D is the only son of C, so D is male and one generation below C. E is the sister of D, so E is another child of C, and she is female. B is the daughter-in-law of F, whose husband has died, so F is an older female (a widow) and the mother of A (and likely of C). We assume all relationships form one consistent family without adoptions. Concept / Approach: The puzzle is solved by placing each person into a generational diagram. We identify grandparents (like F), parents (A, B, C) and children (D, E). Once we understand which generation each person belongs to and who their parents are, it becomes easy to state how E is related to C using a standard kinship term. Step-by-Step Solution: Step 1: Since A and B are a married couple and A is male, A is the husband and B is the wife. Step 2: C is the brother of A, so C is the male sibling of A and in the same generation. Step 3: D is the only son of C. Therefore, C is D's father. Step 4: E is the sister of D, so she is also a child of C (and C's spouse) and is female. Step 5: Because both D and E are described as children in relation to C, C must be their parent. D is explicitly called C's son; E, as D's sister, is C's daughter. Verification / Alternative check: To cross-check, consider the older generation: F is described as having a husband who has died. B is F's daughter-in-law, so B is married to one of F's sons. The sons indicated are A and C; A is explicitly part of the married couple with B. So F is the mother of A (and likely C), making F the grandmother of D and E. In that setup, D and E are the children of C and grandchildren of F, perfectly matching the roles. Why Other Options Are Wrong: “Sister” would describe a same-generation relationship, but E and C are in different generations; C is the parent and E is the child. “Cousin” would require D and E to belong to a different branch of the family, which contradicts the statement that C is D's father and that E is D's sister. “Mother” reverses the generational relationship; nothing suggests that E is older than C or a parent of C. Common Pitfalls: Some candidates incorrectly treat “sister of D” as implying a lateral relationship for E, forgetting that to be a sibling of D she must share the same parent C. Carefully tracing who is the child of whom prevents this error. Writing the family tree generation by generation is especially helpful in such puzzles. Final Answer: E is related to C as his daughter.

Question 12

When Anuj saw Manish, he recalled, "He is the son of the father of my daughter." Who is Manish?

Accepted Answer

Introduction / Context: This reasoning question is phrased as a memory of Anuj when he sees Manish. The key is to understand for whom the relationship is being asked and how the phrase “son of the father of my daughter” should be interpreted. At exam level, the expected answer is usually in terms of Manish's relation to Anuj's daughter, even though the wording can seem ambiguous. Given Data / Assumptions: Anuj says: “He is the son of the father of my daughter.” “My daughter” clearly refers to Anuj's own daughter. We assume standard parent–child relations and that Anuj is the biological father of his daughter. The options given (“Brother-in-law”, “Brother”, “Cousin”, “Uncle”) are all relationships normally expressed relative to a person rather than to their daughter, so we must interpret carefully. Concept / Approach: First we decode the phrase “father of my daughter”. Then we identify who is “the son” of that person. In everyday reasoning, “the son of the father of my daughter” is another child of that same father. This makes him a sibling of the daughter. Since the options include “Brother” but not “Son”, the exam expects us to express the relationship with respect to the daughter: Manish is her brother. Step-by-Step Solution: Step 1: The “father of my daughter” is Anuj himself, because Anuj is recalling this while referring to “my daughter”. Step 2: So the sentence becomes: “He is the son of Anuj.” Step 3: If Manish is the son of Anuj, then relative to Anuj, Manish is his son. Relative to Anuj's daughter, Manish is her brother. Step 4: The question “Who is Manish?” is interpreted using the set of given answers, all of which are relationship words typically used for siblings or relatives, not for children. Step 5: Among the available options, the only one that correctly captures Manish's role in this context is “Brother”, i.e., the brother of Anuj's daughter. Verification / Alternative check: Imagine a simple family: Anuj has a daughter D and a son M (Manish). For D, M is her brother. If the exam wanted Manish's relation directly to Anuj, it would have included “Son” as an option, which it does not. Hence the intended interpretation is his relationship to the daughter, leading to the choice “Brother”. Why Other Options Are Wrong: “Brother-in-law” would imply that Manish is the husband of the daughter's sister or the brother of her husband, neither of which matches the direct parent–child link indicated. “Cousin” would make Manish the child of a sibling of Anuj, not Anuj's own child. “Uncle” would place Manish one generation above the daughter, which contradicts the statement that he is the son of her father. Common Pitfalls: Some students get stuck because the obvious relationship “son” is not in the list of options. When choices are constrained, always re-read the question to see whether the relation is being asked with respect to the speaker or to another person mentioned (here, the daughter). Matching the relation to the available options is a standard checking step in MCQs. Final Answer: Manish is the brother of Anuj's daughter (and therefore Anuj's son).

Question 13

Introducing a man, a woman said, "He is the only son of my mother's mother." How is the woman related to the man?

Accepted Answer

Introduction / Context: This blood-relation question asks you to interpret a description involving “my mother's mother” and “only son” and then determine how the woman is related to the man. These kinds of questions typically aim at relationships like uncle, aunt, niece or nephew, depending on which generational direction is being described. Given Data / Assumptions: The speaker is a woman. She says about a man: “He is the only son of my mother's mother.” “My mother's mother” refers to her maternal grandmother. The man is the only son of that grandmother. We assume no unusual family situations beyond this unless stated. Concept / Approach: First identify who “my mother's mother” is, then who her “only son” is, and finally describe the relationship between the speaker and that son. Generational thinking is crucial: a grandmother's son belongs to the same generation as the speaker's mother, and hence is above the speaker's generation. The opposite direction, from that man down to the speaker, yields the correct kinship term. Step-by-Step Solution: Step 1: “My mother's mother” is the woman's maternal grandmother. Step 2: The “only son of my mother's mother” is the only male child of the grandmother. That person is the brother of the woman's mother. Step 3: The brother of the woman's mother is her maternal uncle. Step 4: Thus, the man being introduced is the woman's uncle. Step 5: The question asks how the woman is related to the man. From the uncle's perspective, the woman is his niece. Verification / Alternative check: We can re-word the original statement as: “He is my maternal uncle.” If that is true, then naturally the reverse relationship is that the woman is his niece. Since the options are written from the woman's perspective in terms of her relation to him, “Niece” is the term that correctly describes her position relative to her uncle. Why Other Options Are Wrong: “Mother” would make the woman the parent of the man, which contradicts the generation difference implied by “grandmother's son”. “Aunt” would place her in the generation above the man, while she is actually a generation below. “Sister” would put them in the same generation and with the same parents, which does not fit the chain of relationships described. Common Pitfalls: It is easy to mix up whether the relation should be stated from the man's side or the woman's side. Always read carefully: “How is the woman related to the man?” means we must answer from the man's point of view. Drawing a small tree with “grandmother”, “mother”, “uncle” and “me” labelled clearly can make such questions much simpler. Final Answer: The woman is the man's niece.

Question 14

A is the father of C and D is the son of B. E is the brother of A. If C is the sister of D, how is B related to E?

Accepted Answer

Introduction / Context: This blood-relation puzzle links five people—A, B, C, D and E—and asks how B is related to E. The information includes father–child relationships, a brother relationship and a sibling relation between C and D. The question ultimately targets an in-law relation (“sister-in-law”), a common theme in such reasoning problems. Given Data / Assumptions: A is the father of C, so A is male and C is A's child. D is the son of B, so D is male and B is a parent (gender not yet specified). E is the brother of A, so E is male and a sibling of A. C is the sister of D, so C and D are siblings, and C is female. We assume siblings share the same pair of parents unless mentioned otherwise. Concept / Approach: We know that C and D are siblings, and that A is the father of C while B is a parent of D. To make them siblings in the usual sense, A and B must be the two parents of both C and D. Once we recognise A and B as a married couple, the connection between B and E (who is A's brother) becomes a typical in-law relationship: B is E's sister-in-law. Step-by-Step Solution: Step 1: Since A is the father of C and C is the sister of D, A is also a parent of D in a standard sibling setup. Step 2: D is described as the son of B. Because C and D are siblings, they typically share both parents. Therefore, B is also a parent of C. Step 3: Thus A and B together are the two parents of C and D, and are naturally treated as a married couple in typical reasoning puzzles (father and mother). Step 4: E is the brother of A, so E is the brother of the husband in this married couple. Step 5: From E's perspective, B is the wife of his brother A. So B is E's sister-in-law. Verification / Alternative check: We can assign sample roles to verify. Let A and B be a married couple. They have two children: C (female) and D (male). E is A's brother. C is the sister of D, as given. D is B's son, and C is A's daughter. In this picture, from E's viewpoint, his brother's wife B is his sister-in-law. All given relations hold and the conclusion is consistent. Why Other Options Are Wrong: “Daughter” would mean B is a child of E, which contradicts the generational information—E and A are brothers, while B is in A's generation, not a generation below. “Brother” would require B to be male and a sibling of E, whereas B is positioned as the partner of A, not as A's sibling. “Husband” would imply B is male and married to E, which does not follow from any given data. Common Pitfalls: Some students overlook that C and D being siblings, combined with “A is father of C” and “D is son of B”, almost forces A and B to be their parents together. Recognising that standard assumption is crucial to discovering the in-law relation. Drawing a simple family diagram can greatly reduce confusion. Final Answer: B is related to E as his sister-in-law.

Question 15

There is a family of six persons A, B, C, D, E and F. Their professions are Lawyer, Doctor, Teacher, Salesman, Engineer and Accountant (one profession each). There are two married couples in the family. D, the Salesman, is married to the lady who is…

Accepted Answer

Introduction / Context: This is a combined blood-relation and logical assignment puzzle. It involves six family members, six different professions and two married couples. We have to use all the clues to reconstruct the family tree and then decide how E is related to F. The final twist is that even after determining they are siblings, the exact gender of E is not fixed, so we must check whether the relation is uniquely determined. Given Data / Assumptions: Family members: A, B, C, D, E and F. Professions: Lawyer, Doctor, Teacher, Salesman, Engineer, Accountant (all different). D is the Salesman and is married to the lady who is the Teacher. The Doctor is married to the Lawyer. F is the Accountant, the 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. There are exactly two married couples in the family. Concept / Approach: We first assign professions and marriages. Then we identify parent–child relations using the clues about daughter-in-law, grandmother and son. This will show that E and F are siblings. Finally, we check whether we can determine E's gender from the information. If we cannot, we cannot choose “brother” or “sister” with certainty, leading us to the “cannot be determined” option. Step-by-Step Solution: Step 1: Since C is the Lawyer and is the daughter-in-law of A, C is female and married to A's child. Step 2: The Doctor is married to the Lawyer, so C's spouse must be the Doctor. That spouse has to be one of the remaining family members. Step 3: D is the Salesman and married to the lady Teacher. Therefore the Teacher must be a female other than C. This lady can be A or B (E is Engineer, F is Accountant, C is Lawyer, D is Salesman). Step 4: F, the Accountant, is the son of B and brother of E. Thus E and F share parent B and another parent (implied to be C, as we will see). Step 5: A is the grandmother of F, so A is one generation above B. Since C is the daughter-in-law of A and married to the Doctor, the Doctor must be B, and C is B's wife. Step 6: Therefore, A is the mother of B (and perhaps of D), making her the grandmother of F. E and F are the children of B (Doctor) and C (Lawyer). Step 7: We already know from the data that E is the unmarried Engineer and F is the Accountant son. This makes E and F siblings, but the statement never specifies whether E is male or female. Verification / Alternative check: The complete consistent picture is: A is grandmother and Teacher (and married to D, the Salesman); B is the Doctor and child of A; C is the Lawyer and B's wife (A's daughter-in-law); E is the Engineer, an unmarried child of B and C; F is the Accountant, the son of B and C. In this model, E and F are brother and sister or possibly two brothers or a brother and a sister, depending only on E's gender, which is not specified. Thus, all clues are satisfied without fixing whether E is male or female. Why Other Options Are Wrong: “Brother” assumes E is male, but the problem never states that; only F is explicitly identified as a son (male). “Sister” assumes E is female, which again is not stated anywhere in the clues. “Cousin” is wrong because E and F clearly share a parent B and a parent C, making them siblings rather than cousins. Common Pitfalls: Many students correctly deduce that E and F are siblings but then rush to pick “brother” because the word “Engineer” might unconsciously sound masculine. Logical puzzles, however, never rely on stereotypes for gender; they require explicit information. When gender is unspecified, you cannot fix the relation as brother or sister. Final Answer: The exact relationship (brother or sister) of E to F cannot be determined from the given information.

Question 16

Rahul's mother is the only daughter of Monika's father. How is Monika's husband related to Rahul?

Accepted Answer

Introduction / Context: This blood-relation question involves two named individuals, Rahul and Monika, and an important phrase “only daughter of Monika's father”. We must carefully determine who Rahul's mother is and then infer how Monika's husband is related to Rahul. The puzzle is built around a unique daughter, which simplifies the reasoning. Given Data / Assumptions: Rahul's mother is the only daughter of Monika's father. We assume Monika is female. Monika's father has exactly one daughter. Monika has a husband whose relationship to Rahul we need to identify. Standard family structure with no step-relations is assumed unless otherwise specified. Concept / Approach: We decode “only daughter of Monika's father” first. This expression describes a single specific person in the family: the one and only daughter of Monika's father. We then identify this person as Rahul's mother. From there, understanding Monika's position in the family and the role of her husband allows us to find his relationship to Rahul. Step-by-Step Solution: Step 1: Consider Monika's father. The phrase “only daughter of Monika's father” means that he has exactly one daughter. Step 2: Since Monika herself is a daughter of her father, and he has only one daughter, that only daughter must be Monika. Step 3: The statement says that Rahul's mother is the only daughter of Monika's father. From Step 2, this means Rahul's mother is Monika. Step 4: If Monika is Rahul's mother, then Monika's husband is the father of Rahul. Step 5: Therefore, Monika's husband is related to Rahul as his father. Verification / Alternative check: We can restate the information as: “Rahul's mother is Monika.” This immediately implies that Monika's husband is Rahul's father. No other common family configuration fits the wording, given the “only daughter” condition. This confirms our conclusion. Why Other Options Are Wrong: “Uncle” would place Monika's husband as a brother of one of Rahul's parents, but he is clearly described as the husband of Rahul's mother instead. “Grandfather” would make Monika's husband one generation above Rahul's parents, which contradicts the fact that he is married to Rahul's mother. “Brother” would place him in the same generation as Rahul, which is inconsistent with him being a spouse of Rahul's mother. Common Pitfalls: Students sometimes overcomplicate the expression “only daughter of Monika's father” and imagine extra siblings, but the word “only” rules that out. Always pay attention to such restrictive words; they often reduce the problem to a single clear possibility. Final Answer: Monika's husband is Rahul's father.

Question 17

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

Accepted Answer

Introduction / Context: This blood-relation question uses a photograph scenario and a statement made by Asha to relate herself to the man in the picture. The phrase “His mother's only daughter is my mother” is the crucial piece of information. We need to decode it carefully and then state Asha's relationship to the man. Given Data / Assumptions: Asha is pointing to a man in a photograph. She says: “His mother's only daughter is my mother.” The man in the photo is male. We assume straightforward family relations without step-relations. We must express the relationship from Asha's point of view. Concept / Approach: We first interpret “his mother's only daughter” and then link that to Asha. If that only daughter is Asha's mother, we can find the generational relationship between the man and Asha. The key is recognising that both the man and Asha are children of the same woman or of siblings, and then determining who is the uncle or niece. Step-by-Step Solution: Step 1: “His mother” refers to the mother of the man in the photograph. Step 2: “His mother's only daughter” means that this woman (his mother) has exactly one daughter. Step 3: Asha says that this only daughter is her mother. So Asha's mother is the only daughter of the man's mother. Step 4: That means the man's mother is Asha's grandmother (because Asha's mother is her daughter). Step 5: The man himself is a child of this grandmother, so he is a son of Asha's grandmother. That makes him a sibling of Asha's mother, i.e., Asha's maternal uncle. Step 6: If the man is Asha's uncle, then from his perspective Asha is his niece. Verification / Alternative check: We can rewrite the statement substituting labels: “His mother's only daughter (my mother) is the sister of the man, and I am her child.” This describes exactly the situation where the man is the woman's brother and the woman is the child's mother, which by definition makes the child (Asha) the man's niece. Why Other Options Are Wrong: “Nephew” is a male term and would be used if Asha were male. The question identifies her as Asha, typically interpreted as a female name, and we answer from her perspective. “Sister” would mean Asha and the man share the same parents, but the chain shows that her mother is his mother's daughter, putting another generation in between. “Wife” would require a marital relationship, which is not supported by any part of the description. Common Pitfalls: Students sometimes incorrectly assume that “his mother's only daughter” must be the man himself, but he is clearly identified as a male. That daughter is instead his sister, who is also Asha's mother. Being careful about gender words like “daughter” and “son” is essential to avoid such errors. Final Answer: Asha is the man's niece.

Question 18

In this blood relation reasoning question, a lady points to a photograph and tells Pramod, "I am the only daughter of this lady, and her son is your maternal uncle." Based on this information, how is the speaker related to Pramod's father?

Accepted Answer

Introduction / Context: This verbal reasoning question tests the candidate's understanding of family relationships and careful reading of phrases like maternal uncle and only daughter. The goal is to determine how the speaking lady, who is describing a photograph and her family, is related to Pramod's father. Such questions are common in competitive exams and require a clear family tree in mind. Given Data / Assumptions: • The lady points to a woman in the photograph and says that she herself is the only daughter of that woman.• The same woman in the photograph has a son, and that son is Pramod's maternal uncle.• A maternal uncle is the brother of one's mother.• Standard assumptions are used: there is no hidden adoption or remarriage unless stated, and family terms have their usual meanings. Concept / Approach: The core idea is to translate the verbal description into a simple family tree. If a person is someone's maternal uncle, he must be the brother of that person's mother. Once we identify who the mother is and to which generation the speaker belongs, we can connect her to Pramod and then to Pramod's father. The relationship of the speaker to Pramod's father then becomes straightforward: if she is Pramod's mother, she must be the wife of his father. Step-by-Step Solution: Step 1: Let the lady in the photograph be called X. The speaker says she is the only daughter of X.Step 2: X also has a son, and that son is described as Pramod's maternal uncle.Step 3: If X's son is Pramod's maternal uncle, that son must be the brother of Pramod's mother.Step 4: This means X is the mother of both Pramod's maternal uncle and Pramod's mother, so X is Pramod's maternal grandmother.Step 5: The speaker is the only daughter of X, so she must be Pramod's mother, because the only daughter of the maternal grandmother who shares the same mother and uncle relation with Pramod is his own mother.Step 6: If the speaker is Pramod's mother, then relative to Pramod's father, she is his wife. Verification / Alternative Check: As a quick check, imagine a typical family: a grandmother with two children, one son and one daughter. The son is the maternal uncle of the grandchild, and the daughter is the child's mother. That matches this situation exactly. No other role for the speaker maintains both conditions that she is the only daughter of the lady in the photo and that the lady's son is Pramod's maternal uncle. Why Other Options Are Wrong: Sister in law of Pramod's father: This would require the lady to be the sister of Pramod's mother or the wife of Pramod's father's brother, which contradicts the fact that she is Pramod's mother.Sister of Pramod's father: That would make the speaker a paternal aunt, not the daughter of Pramod's maternal grandmother in this configuration.Aunt of Pramod's father: This would push her one generation above Pramod's father, which does not fit the maternal uncle relation described.Relationship cannot be determined: The information is sufficient to infer that the speaker is Pramod's mother and therefore the wife of his father. Common Pitfalls: Candidates often confuse maternal uncle with paternal uncle and may wrongly try to connect the uncle to Pramod's father. Another common mistake is to assume that the lady in the photograph is Pramod's mother, whereas she is actually Pramod's maternal grandmother. Carefully tracking each phrase, especially only daughter and maternal uncle, prevents these errors. Final Answer: The speaker is Pramod's mother and therefore the wife of Pramod's father.

Question 19

In this blood relation puzzle, Q's mother is described as the sister of P and the daughter of M, while S is the daughter of P and the sister of T. Using this information, how is M related to T?

Accepted Answer

Introduction / Context: This question examines the ability to track relationships across two generations. The family members Q, P, M, S and T are related through parent and sibling links, and the task is to determine the exact generational position of M relative to T. The question also highlights a typical exam trap where the gender of an ancestor is not explicitly given, so the safest description is often a neutral family term like grandparent. Given Data / Assumptions: • Q's mother is the sister of P.• Q's mother is also the daughter of M.• S is the daughter of P.• S is the sister of T, which means P is also a parent of T.• Standard family structure with no adoption or remarriage is assumed. Concept / Approach: We first identify the direct descendants of M and then determine their relationship to T. If M is the parent of Q's mother, and Q's mother is the sibling of P, that means M is also the parent of P. Then we use the fact that P is a parent of T, because S is P's daughter and T is S's sibling. Once we know that P is a child of M and T is a child of P, M must be one generation above P and two generations above T, which makes M a grandparent of T. The question does not specify whether M is male or female, so we must answer using a gender neutral term. Step-by-Step Solution: Step 1: From the statement, Q's mother is the daughter of M, so M is a parent of Q's mother.Step 2: Q's mother is also the sister of P, so P and Q's mother are siblings, both children of M.Step 3: S is the daughter of P, and S is a sister of T, so P is a parent of both S and T.Step 4: This makes P the parent of T and M the parent of P.Step 5: Therefore, M is one generation above P and two generations above T.Step 6: Being two generations above T, M is T's grandparent, but the exact gender of M is not given in the question. Verification / Alternative Check: Make a simple tree: put M at the top, with two children, Q's mother and P. From P draw two children, S and T. In that diagram, M is clearly one step above P and two steps above T. Since no information is provided about whether M is male or female, the safest and most correct description is grandparent, which covers both grandfather and grandmother. Why Other Options Are Wrong: Grandfather of T: This assumes M is male, which is not provided anywhere in the question.Grandmother of T: This assumes M is female, which is also not provided.Father of T: P is the parent directly connected to T, not M, so M cannot be T's father.Uncle or aunt of T: M is clearly two generations above T, not a sibling of a parent, so this is incorrect. Common Pitfalls: Candidates often rush and immediately label M as grandfather or grandmother, forgetting that the question does not specify a gender. Others fail to notice that M is an ancestor of both Q and T, and mistakenly place M as a parent instead of a grandparent. Drawing a quick family diagram is a very effective way to avoid these errors in exams. Final Answer: M is the grandparent of T (either grandfather or grandmother).

Question 20

In this blood relation question, Kailash points to an old man and says, "His son is my son's uncle." Based on this statement, how is the old man related to Kailash?

Accepted Answer

Introduction / Context: The question presents a classic blood relation scenario where a single sentence connects three different people. Kailash describes an old man and the old man's son in relation to his own son. We must use this information to find the relationship between the old man and Kailash. Such problems test the ability to decode phrases like my son's uncle and to distinguish between paternal and maternal uncles. Given Data / Assumptions: • Kailash points to an old man.• He says, "His son is my son's uncle."• An uncle of a child is either the brother of the child's father (paternal uncle) or the brother of the child's mother (maternal uncle).• Standard exam convention assumes the uncle mentioned in this kind of question is the paternal uncle unless there is specific information about the mother. Concept / Approach: We interpret my son's uncle as Kailash's brother in the usual exam setting. If the old man's son is Kailash's brother, then they share the same father. Therefore the old man must be Kailash's father. The key to solving the question is recognizing which person is positioned one generation above both Kailash and the old man's son and then matching that role with the description of the old man. Step-by-Step Solution: Step 1: Let the old man be X and his son be Y.Step 2: Kailash says that Y is his son's uncle.Step 3: In standard reasoning questions, my son's uncle is usually my brother, that is, the brother of the child's father.Step 4: So Y can be taken as Kailash's brother.Step 5: If Y is Kailash's brother, both Y and Kailash must be sons of the same father.Step 6: The father of Y is the old man X. Hence the old man X is also the father of Kailash. Verification / Alternative Check: Visualise a simple family: an old man with two sons. One son is Kailash, and the other is Y. Kailash has a son. The other son Y is then the paternal uncle of Kailash's child. This perfectly matches the statement his son is my son's uncle. No other role of the old man can satisfy this description as cleanly in the standard exam interpretation. Why Other Options Are Wrong: Grandfather of Kailash: If the old man were Kailash's grandfather, the old man's son would be Kailash's father, not his brother, and the description would not match.Father in law of Kailash: In that case, the old man's son would be Kailash's wife, which is impossible.Uncle of Kailash: If the old man were Kailash's uncle, then his son would be Kailash's cousin, not his son's uncle in the standard sense.Relationship cannot be determined: The information is clear enough to establish that the old man is Kailash's father under standard assumptions. Common Pitfalls: Many candidates overcomplicate the problem by considering both maternal and paternal uncles simultaneously and then feel that the relation cannot be determined. However, exam questions normally assume the paternal side unless explicitly told otherwise. Another mistake is to treat the old man as Kailash's grandfather instead of his father, which breaks the relationship described in the statement. Final Answer: The old man is the father of Kailash.
