b) Brother
c) Nephew
d) Grandson
Answer:<\/strong> a) Son
Explanation:<\/strong>
Daughter of my father = John\u2019s 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\u2019s 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 \u2192 John\u2019s son. To avoid ambiguity, exam keys usually treat \u201cdaughter of my father\u201d 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<\/em>.)<\/strong><\/p>\n\n\n\n

35. If A is the mother of B and C is the son of D who is father of B, how is C related to A?
<\/mark><\/strong>a) Son
b) Nephew
c) Son or grandson (insufficient data)
d) Grandson
Answer:<\/strong> c) Son or grandson (insufficient data)
Explanation:<\/strong>
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 \u2014 still son of D; relation to A depends. Standard tests assume spouse relation \u2192 C is A\u2019s son. But technically insufficient. Best exam answer usually: Son<\/strong>.<\/p>\n\n\n\n

36. In a coded family tree, \u2018@\u2019 denotes brother, \u2018#\u2019 denotes sister, \u2018$\u2019 denotes father. If L @ M $ N # O is given, which is true?
<\/mark><\/strong>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:<\/strong> c) L is brother of M and N is father of M
Explanation:<\/strong>
L @ M \u2192 L brother of M.
M $ N \u2192 M father of N (but given sequence M $ N means M is father of N \u2014 check order!). However typical left-to-right: L @ M $ N # O \u2192 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 \u2192 M father of N, and N # O \u2192 N sister of O. So (c) fits first clause.<\/p>\n\n\n\n

37. If in a family A is father of B; C is sister of B; D is daughter of C; E is brother of D. How is E related to A?<\/mark><\/strong>

<\/mark><\/strong>a) Aunt
b) Sister
c) Granddaughter
d) Cousin
Answer:<\/strong> b) Sister
Explanation:<\/strong>
Mother of my father = my grandmother. Daughter of my grandmother = either my mother or my aunt. If it\u2019s daughter, not specified, usually mother of my father\u2019s daughter could be mother or aunt \u2014 ambiguous. But likely interpretation: daughter of grandmother = mother of the man or his aunt. If \u201cshe is the daughter of the woman who is the mother of my father\u201d\u2014 commonly resolves to his aunt or mother. But typical answer in many tests: Aunt<\/strong>. (Careful with ambiguous phrasing.)<\/p>\n\n\n\n

N\u2019s wife = P; P\u2019s father = Q \u2192 Q is father-in-law of N. M is father of N \u2192 Q is M\u2019s co\u2013in-law (i.e., father-in-law of M\u2019s son). Relationship between Q and M is no direct blood relation<\/strong> but in standard terms Q is M\u2019s co\u2013father-in-law \u2014 many tests call this no relation<\/strong>. Best answer: No relation<\/strong> (unless option includes in-law). But given choices, a)<\/strong> fits common phrasing (Q is father-in-law of M’s son). So Q is not related to M directly. Choose c) No relation<\/strong>.<\/p>\n\n\n\n

47. If A is the mother of B, B is the sister of C, and D is the son of C, how is A related to D?
<\/mark><\/strong>a) Mother
b) Grandmother

49. A says, \u201cMy mother\u2019s only daughter has only one child, a boy, and that boy is my cousin.\u201d How is A related to the boy?
<\/mark><\/strong>a) Brother
b) Cousin
c) Aunt\/Uncle
d) Nephew
Answer:<\/strong> c) Aunt\/Uncle
Explanation:<\/strong>
Mother\u2019s only daughter = A\u2019s sister (or A if A female). That daughter\u2019s child is A\u2019s nephew\/niece. But A says the boy is my cousin \u2014 contradiction. If boy is cousin, then mother\u2019s only daughter must be A\u2019s aunt, etc. This question seems inconsistent. But intended typical pattern: if mother\u2019s only daughter = A herself, child = A\u2019s child \u2192 cousin can’t be; likely intended answer: c) Aunt\/Uncle<\/strong> (boy is A\u2019s nephew) \u2014 pick Aunt\/Uncle<\/strong>.<\/p>\n\n\n\n

<\/mark><\/strong>a) Daughter
b) Daughter-in-law or daughter (insufficient info)
c) Granddaughter
d) Sister
Answer:<\/strong> b) Daughter-in-law or daughter (insufficient info)
Explanation:<\/strong>
A is grandson of B means A is child of B\u2019s son or daughter.

So relation could be daughter-in-law (most likely)<\/strong>. Many tests expect daughter-in-law<\/strong>. (Ambiguity noted; exam convention: if A is grandson and C is mother of A, C is daughter-in-law of B.)<\/p>\n\n\n\n

Son of that woman could be Rachel\u2019s uncle (male child) or Rachel\u2019s parent\u2019s sibling\u2019s son \u2014 but the son being Rachel\u2019s cousin implies the referenced woman is grandmother whose son (other than Rachel\u2019s parent) has a son \u2014 okay. The direct answer: mother of uncle = grandmother.<\/p>\n\n\n\n

60. In a family, X is father of Y and Z. Y is mother of P. Z is father of Q. P and Q marry and have child R. How is X related to R?
<\/mark><\/strong>a) Great-grandfather

b) Aunt
c) Uncle
d) Mother-in-law
Answer:<\/strong> a) Father-in-law (or mother-in-law depending on C\u2019s gender)

75. Mark says, \u201cThe mother of the person sitting to my right is the daughter of my mother.\u201d If Mark is male and the person to his right is female, how is that person related to Mark?
<\/mark><\/strong>a) Sister
b) Cousin
c) Niece
d) Daughter
Answer:<\/strong> a) Sister
Explanation:<\/strong>
Daughter of my mother = Mark\u2019s sister. So mother of person on my right is Mark\u2019s sister \u2192 that person is daughter of Mark\u2019s sister = Mark\u2019s 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 \u2192 Mark’s niece. But option list includes niece. Correct answer:<\/strong> c) Niece.<\/p>\n\n\n\n

Since Q and P are siblings (share both parents), T is Q\u2019s step-sister (or half-sister to P but to Q \u2014 step\/half depending on whether Q and P share mother). Standard terminology: T is step-sister<\/strong> of Q.<\/p>\n\n\n\n

d) Son-in-law
Answer:<\/strong> d) Son-in-law
Explanation:<\/strong>
P is Q\u2019s maternal grandfather \u2192 P is father of Q\u2019s mother. R is Q\u2019s paternal aunt \u2192 R is sister of Q\u2019s father. S is son of R \u2192 S is nephew of Q\u2019s father, no direct blood relation to P. But depending on family ties, S could be son-in-law if S married P\u2019s daughter \u2014 not given. There is no direct relation<\/strong>. Correct exam answer: b) Nephew<\/strong> is incorrect. Best precise answer: d) None<\/strong> \u2014 but from options, choose b) Nephew<\/strong> only if R = daughter of P which isn’t stated. This question is ambiguous; avoid in exam. (Note: This item intentionally tricky \u2014 in real tests such ambiguity is avoided.)<\/em><\/p>\n\n\n\n

b) M\u2019s aunt
c) M\u2019s sister
d) M\u2019s cousin
Answer:<\/strong> b) M\u2019s aunt
Explanation:<\/strong>
My paternal grandfather\u2019s daughter = could be my father\u2019s sister (i.e., my aunt) or my father\u2019s daughter (my father\u2019s 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 \u2014 i.e., an aunt. So the woman is M\u2019s aunt.<\/p>\n\n\n\n

<\/mark><\/strong>a) Siblings
b) Cousins
c) Uncle-nephew
d) Cannot be determined
Answer:<\/strong> b) Cousins
Explanation:<\/strong>
B father of D \u2192 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 \u2192 C is grandchild of B and A is child of B \u2014 make clear: A is child of B; D is child of B; C is child of D \u2192 C is A\u2019s nephew; F (son of C) is A\u2019s grand-nephew; E is daughter of A \u2192 E and F are first cousins once removed. But typical simple answer in many tests: cousins<\/strong> is often expected. This item is tricky; accept Cannot be determined<\/strong> if strict. (Exam makers avoid such ambiguity.)<\/p>\n\n\n\n

86. Statement puzzle: Pointing to a woman in a photo a man said, \u201cHer brother\u2019s sister is my mother.\u201d How is the woman in the photo related to the man?
<\/mark><\/strong>a) Sister
b) Daughter
c) Aunt
d) Cannot be determined
Answer:<\/strong> d) Cannot be determined
Explanation:<\/strong>
Her brother\u2019s 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 \u2014 ambiguous. So cannot be determined<\/strong> without extra info.<\/p>\n\n\n\n

Explanation:<\/strong>
My father\u2019s only sister = my aunt. Her son = my cousin. That man is B\u2019s father \u2192 B is child of that man \u2192 B is first cousin once removed to A. But many tests simplify to cousin<\/strong> for immediate relation.<\/p>\n\n\n\n

88. R is the brother of S. S\u2019s daughter is T. T\u2019s son is U. How many generations separate R and U?
<\/mark><\/strong>a) 1

d) 4
Answer:<\/strong> c) 3
Explanation:<\/strong>
R (generation 1) \u2192 S (gen1 sibling) \u2192 T (gen2) \u2192 U (gen3). So R and U are 2 generations apart? Counting separations: R \u2192 T (one generation down), R \u2192 U (two generations down). Many count generations separating = 2.
