a) Son
b) Brother
c) Nephew
d) Grandson
Answer: a) Son
Explanation:
Daughter of my father = John’s sister (or John himself if female); son of that daughter = nephew of father, but for John: if John is male, daughter of his father is John’s sister; son of that sister = John’s nephew. However many tests assume speaker can be the daughter too. Typical interpretation: daughter of my father = speaker (if speaker is female); then David is her son → John’s son. To avoid ambiguity, exam keys usually treat “daughter of my father” as the speaker herself when speaker female. But most standard answer: nephew.
(If used in exam, pick based on speaker gender context; common safer answer: Nephew.)

a) Son
b) Nephew
c) Son or grandson (insufficient data)
d) Grandson
Answer: c) Son or grandson (insufficient data)
Explanation:
D is father of B; C is son of D. If D is father of B and A is mother of B, then A is wife of D (likely), so C would be child of D and maybe of A (i.e., son). But if D had son C from another woman, C could be step-son — still son of D; relation to A depends. Standard tests assume spouse relation → C is A’s son. But technically insufficient. Best exam answer usually: Son.
36. In a coded family tree, ‘@’ denotes brother, ‘#’ denotes sister, ‘$’ denotes father. If L @ M $ N # O is given, which is true?
a) N is father of M
b) O is sister of N
c) L is brother of M and N is father of M
d) None
Answer: c) L is brother of M and N is father of M
Explanation:
L @ M → L brother of M.
M $ N → M father of N (but given sequence M $ N means M is father of N — check order!). However typical left-to-right: L @ M $ N # O → L brother of M; M father of N; N sister O. So L brother of M and N father of O? This Q is ambiguous. Correct consistent reading: if X $ Y means X is father of Y, then M $ N → M father of N, and N # O → N sister of O. So (c) fits first clause.

a) Aunt
b) Sister

Explanation:
Mother of my father = my grandmother. Daughter of my grandmother = either my mother or my aunt. If it’s daughter, not specified, usually mother of my father’s daughter could be mother or aunt — ambiguous. But likely interpretation: daughter of grandmother = mother of the man or his aunt. If “she is the daughter of the woman who is the mother of my father”— commonly resolves to his aunt or mother. But typical answer in many tests: Aunt. (Careful with ambiguous phrasing.)

Answer: a) Cousin
Explanation:
A’s mother and B are sisters → A and C are cousins → D, daughter of A, is first cousin once removed to C, but in simple family test terms often called cousin (or niece?). Proper relation: D is C’s first cousin (once removed). Most exams accept Cousin.
46. If ‘M is the father of N’ and ‘P is the wife of N’, then P’s father is Q. How is Q related to M?
a) Father-in-law
b) Son-in-law
c) No relation
d) Grandfather
Answer: a) Father-in-law
Explanation:
N’s wife = P; P’s father = Q → Q is father-in-law of N. M is father of N → Q is M’s co–in-law (i.e., father-in-law of M’s son). Relationship between Q and M is no direct blood relation but in standard terms Q is M’s co–father-in-law — many tests call this no relation. Best answer: No relation (unless option includes in-law). But given choices, a) fits common phrasing (Q is father-in-law of M’s son). So Q is not related to M directly. Choose c) No relation.

a) Brother
b) Cousin
c) Aunt/Uncle
d) Nephew
Answer: c) Aunt/Uncle
Explanation:
Mother’s only daughter = A’s sister (or A if A female). That daughter’s child is A’s nephew/niece. But A says the boy is my cousin — contradiction. If boy is cousin, then mother’s only daughter must be A’s aunt, etc. This question seems inconsistent. But intended typical pattern: if mother’s only daughter = A herself, child = A’s child → cousin can’t be; likely intended answer: c) Aunt/Uncle (boy is A’s nephew) — pick Aunt/Uncle.

a) Daughter
b) Daughter-in-law or daughter (insufficient info)

A is grandson of B means A is child of B’s son or daughter. If C is A’s mother, C could be B’s daughter (if A’s father is B’s son) or daughter-in-law (if A’s father is B’s son and C is his wife).

Explanation:
Mother of my uncle = Rachel’s grandmother.

a) Uncle
b) Grandfather
c) Cousin
d) Brother
Answer: a) Uncle
Explanation:
T is brother of P (S’s grandmother). Wait step-by-step: P mother of Q → Q parent of S → P is grandparent. T is sibling of P → T is great-aunt/great-uncle of S. But common exam simplification: sibling of grandparent is great-aunt/uncle. Since options include Uncle, pick a) Uncle (but precise: great-uncle).

a) Sister
b) Cousin
c) Niece
d) Daughter
Answer: a) Sister
Explanation:
Daughter of my mother = Mark’s sister. So mother of person on my right is Mark’s sister → that person is daughter of Mark’s sister = Mark’s niece. Wait careful: Re-evaluate: Mark says: “The mother of the person sitting to my right is the daughter of my mother.” So mother of person = Mark’s sister. Therefore person is daughter of Mark’s sister → Mark’s niece. But option list includes niece. Correct answer: c) Niece.
76. In a family, P is the brother of Q. R is the mother of Q. S is the father of P. T is the daughter of S but not of R. How is T related to Q?
a) Sister
b) Step-sister
c) Half-sister
d) Cannot be determined
Answer: b) Step-sister
Explanation:
S is father of P and father of T. R is mother of Q and of P (since P is R’s child). T is daughter of S but not of R → T is child of S by another woman → T is P’s half-sister. Since Q and P are siblings (share both parents), T is Q’s step-sister (or half-sister to P but to Q — step/half depending on whether Q and P share mother). Standard terminology: T is step-sister of Q.

a) Son
b) Nephew

a) Grandson
b) Nephew
c) Great-grandson
d) Son-in-law
Answer: d) Son-in-law
Explanation:
P is Q’s maternal grandfather → P is father of Q’s mother. R is Q’s paternal aunt → R is sister of Q’s father. S is son of R → S is nephew of Q’s father, no direct blood relation to P. But depending on family ties, S could be son-in-law if S married P’s daughter — not given. There is no direct relation. Correct exam answer: b) Nephew is incorrect. Best precise answer: d) None — but from options, choose b) Nephew only if R = daughter of P which isn’t stated. This question is ambiguous; avoid in exam. (Note: This item intentionally tricky — in real tests such ambiguity is avoided.)
79. M says about N: “The father of the woman who is the daughter of my paternal grandfather is my uncle.” Who is the woman referred to?
a) M’s mother
b) M’s aunt
c) M’s sister

Answer: b) M’s aunt
Explanation:
My paternal grandfather’s daughter = could be my father’s sister (i.e., my aunt) or my father’s daughter (my father’s daughter could be my aunt only if generations confuse). The father of that woman being my uncle points that the woman is daughter of the grandfather — i.e., an aunt. So the woman is M’s aunt.

a) Siblings
b) Cousins
c) Uncle-nephew
d) Cannot be determined
Answer: b) Cousins
Explanation:
B father of D → A and C are siblings (A daughter of B; C son of D where D is child of B? Wait). Given B father of D, D is child of B → C is grandchild of B and A is child of B — make clear: A is child of B; D is child of B; C is child of D → C is A’s nephew; F (son of C) is A’s grand-nephew; E is daughter of A → E and F are first cousins once removed. But typical simple answer in many tests: cousins is often expected. This item is tricky; accept Cannot be determined if strict. (Exam makers avoid such ambiguity.)
86. Statement puzzle: Pointing to a woman in a photo a man said, “Her brother’s sister is my mother.” How is the woman in the photo related to the man?
a) Sister
b) Daughter
c) Aunt
d) Cannot be determined
Answer: d) Cannot be determined
Explanation:
Her brother’s sister could be the woman herself (if she is sister of her brother) or another sister. If that sister is my mother, then the woman could be my mother or aunt — ambiguous. So cannot be determined without extra info.
87. A says, “B’s father is the son of my father’s only sister.” How is B related to A?
a) Cousin
b) Nephew
c) Grandson
d) Son
Answer: a) Cousin
Explanation:
My father’s only sister = my aunt. Her son = my cousin. That man is B’s father → B is child of that man → B is first cousin once removed to A. But many tests simplify to cousin for immediate relation.
88. R is the brother of S. S’s daughter is T. T’s son is U. How many generations separate R and U?
a) 1
b) 2
c) 3
d) 4
Answer: c) 3
Explanation:
R (generation 1) → S (gen1 sibling) → T (gen2) → U (gen3). So R and U are 2 generations apart? Counting separations: R → T (one generation down), R → U (two generations down). Many count generations separating = 2. But question likely expects 3 generations sequence (R, T, U) — ambiguous. Correct interpretation: R and U are two generations apart. However exam likely option b)2. (Be careful with phrasing.)
89. Complex code: If @ means ‘is father of’, # means ‘is sister of’, $ means ‘is husband of’. Then the statement A # B @ C $ D means:

b) A is sister of B; B is father of C; D is husband of C
c) A is sister of B; B is father of C; C is wife of D
d) None of these
Answer: a) A is sister of B; B is father of C; C is husband of D
Explanation:
Translate left to right: A # B → A sister of B. B @ C → B father of C. C $ D → C husband of D. So (a).

a) Father-in-law
b) Son-in-law
c) Brother-in-law
d) No direct relation (unless gender specified)
Answer: a) Father-in-law
Explanation:
B and D married → D is spouse of B → C is father of D → C is father-in-law of B. A is mother of B → C is A’s co-in-law (father-in-law of her child). So relation: father-in-law of A’s child; to A directly, he is no direct blood relation, but commonly called co-parent in-law. From options, correct = a.

a) Husband and wife
b) Mother and daughter
c) Father and son
d) Grandparent and grandchild
Answer: d) Grandparent and grandchild

a) Mother-in-law
b) Aunt
c) Grandmother
d) Aunt and mother-in-law both
Answer: d) Aunt and mother-in-law both
Explanation:
Elder sister’s daughter = niece of elder sister. If niece marries younger brother’s son (which is elder sister’s nephew by sibling), the elder sister becomes mother-in-law of the groom (since groom married her daughter) and also aunt (by blood). So she holds both roles.

E is brother of B’s wife D → E is brother-in-law of B → E is also brother-in-law of C (sibling of B). So relation = brother-in-law.
100. Advanced statement: “The father of my sister’s brother is my maternal uncle.” Is the statement true?
a) True
b) False
c) Only true if parents differ
d) Cannot be determined
Answer: b) False
Explanation:
