Blood Relations Practice Test Questions - Verbal Reasoning

"Father of her uncle" is the girl's grandfather. "Daughter of [that grandfather]" is one of the grandfather's daughters -- this could be the girl's paternal aunt, OR, if "uncle" refers to her mother's brother, this grandfather is her maternal grandfather, and his daughter could actually be the girl's own mother.

"Son of [that daughter]" is then either: (a) the son of an aunt, i.e. the girl's cousin, or (b) the son of the girl's own mother, i.e. the girl's own brother.

Since "uncle" is not specified as paternal or maternal, both readings are valid, so the boy could be either the girl's cousin or her brother.

"A's son is D's brother" means A's son and D share the same parents -- so D is also A's child (A's daughter). Since C and D are sisters, C is A's daughter too.

B is A's brother, which makes B the uncle of all of A's children, including C.

So B is related to C as her Uncle.

The "brother-in-law of my friend's mother" is a person from the same generation as the friend's parents (either the friend's mother's sister's husband, or the friend's father's brother).

The girl is the youngest daughter of this person, which places the girl in the same generation as Ms. X's friend -- making her a cousin of the friend.

B's parents are D and A, so D must be A's husband (since B is a "daughter of D and A"). E is the brother of A's husband, so E is D's brother.

F is the mother of E, and since E and D are brothers (sharing the same parents), F is also D's mother.

B is the granddaughter of C, and since F already accounts for D's mother, C must be D's father (F's husband) -- completing the parent-couple {F, C} of both D and E.

Since C is the father of D and E (as brothers sharing the same parents), C is related to E as his Father.

B is the mother of C, and D is C's sister, so D shares the same mother -- D is also B's daughter.

A is married to B, and since B is confirmed as the mother, A takes the role of father in this family. So D, being B's daughter, is also A's daughter.

D is related to A as his Daughter.

R and Q are one couple; R's son is P, so R and Q are P's parents. P and U are the second couple (U is mother of T, and P's daughter is T), so U and S are also P's children.

Since P's daughter T is a granddaughter of both R and Q (T's grandparents through P), and Q's exact gender is not fixed by the clues, only the statement that does not depend on which of R/Q is male or female can be confirmed: T is granddaughter of Q.

Since C and Q are sisters and Z is the mother of Q, Z is also the mother of C.

P is the son of Z, so P is a sibling of C (and of Q).

A is the son of C. Since P is C's brother, P is A's (maternal) uncle.

D x E means D is the brother of E. E + F means E is the father of F.

So D is E's brother, and E is F's father -- meaning D is F's (paternal) uncle.

"The only son of my mother" means Suresh himself, since Suresh is stated to be the only son of his mother.

So the boy in the photograph is the son of Suresh, making Suresh the boy's father.

E is the father of B, and D is the son of E, so D is a child of E -- making D a sibling of B.

Since D is specified as a "son," D is male, so D is the brother of B.

"My son's wife" is Sharma's daughter-in-law. Her daughter (with Sharma's son) is Sharma's granddaughter.

The mother of that granddaughter is the son's wife herself -- so "she" is Sharma's daughter-in-law.

R is mother of Q, and P is Q's sister, so P is also R's daughter.

R is sister of S, and T is mother of S, so T is also R's mother (since R and S are siblings and share a mother).

So T is R's mother, and P is R's daughter -- meaning T is P's grandmother.

Dr. Madhu's brother (the engineer) is the son of Mr. Murli.

Since Dr. Madhu's brother is Dr. Madhu's own sibling, and Murli is that brother's father, Murli is also Dr. Madhu's father.

B is the son of P, so P is B's mother.

A is B's brother, so A is also P's child -- A is P's son.

Q's mother is P's sister and S's daughter, so S is also P's parent (P and Q's mother are siblings, sharing parent S).

Since P is specified as female ("sister of Q"), P is the mother of her children A and H. G, being the father of H (P's child), must be P's husband.

G is therefore married into S's family -- S's son-in-law.
