Question 23Question →

Consider the following coded relationship definitions between two individuals:
- $A \ \tau \ B$ means ' $A$ is the father of $B$ '
- $A \ \sigma \ B$ means ' $A$ is the brother of $B$ '
- $A \ \mu \ B$ means ' $A$ is the mother of $B$ '
- $A \ \delta \ B$ means ' $A$ is the daughter of $B$ '

Based on the expression $U \ \tau \ V \ \sigma \ W \ \mu \ X \ \delta \ Y$ , how is $U$ related to $Y$ ?

Father-in-law

Father

Son-in-law

Brother-in-law

Show answer & explanation

Answer: Father-in-law

Answer

Father-in-law

Breaking down the expression:

U \ \tau \ V

means

U

is the father of

V

.

V \ \sigma \ W

means

V

is the brother of

W

, so

U

is also the father of

W

. Next,

W \ \mu \ X

means

W

is the mother of

X

. Finally,

X \ \delta \ Y

means

X

is the daughter of

Y

. Since

X

is the daughter of mother

W

and parent

Y

,

Y

must be the male parent (father) of

X

, which means

Y

is married to

W

. Since

U

is the father of

W

,

U

is the father of

Y

's wife, making

U

the father-in-law of

Y

. Thus, the correct answer is Father-in-law.

Step-by-Step Solution

1

Decode the first segment

U \ \tau \ V \ \sigma \ W

U

is a male and the father of

V

.

V

is a male and the brother of

W

. Therefore,

U

is also the father of

W

.

Since

V

and

W

are siblings, they share the same father,

U

.

2

Decode the second segment

W \ \mu \ X \ \delta \ Y

W

is female and the mother of

X

.

X

is female and the daughter of

Y

.

Since

X

is the child of both mother

W

and parent

Y

,

Y

must be the father of

X

and the husband of

W

.

3

Determine the relationship between

U

and

Y

U

is the father of

W

, and

Y

is the husband of

W

. Thus,

U

is the father-in-law of

Y

.

The father of one's spouse is defined as one's father-in-law.

Question 24Question →

Based on the family relationships described below, match each person in List I with their correct relationship to $Q$ in List II.

Family Narrative:
In a family of six members— $M, N, O, P, Q,$ and $R$ :
- $M$ is the father of $N$ .
- $O$ is the mother-in-law of $P$ .
- $P$ is the wife of $N$ .
- $Q$ is the daughter of $P$ .
- $R$ is the brother of $M$ .

Click a left item, then click its matching right item

Show answer & explanation

Answer

M

matches with Paternal Grandfather,

O

matches with Paternal Grandmother,

P

matches with Mother, and

R

matches with Grand-uncle (Brother of Paternal Grandfather).

Each member's relationship to

Q

is systematically established by building the family tree from

Q

's parents (

N

and

P

) upwards to the paternal grandparents (

M

and

O

) and collaterals (

R

).

Step-by-Step Solution

1

Determine the direct parentage of

Q

P

is the mother of

Q

, and

N

(the husband of

P

) is the father of

Q

.

Since

Q

is the daughter of

P

,

P

is her mother.

P

is married to

N

, making

N

the father.

2

Trace the paternal grandparent lineage

M

is the paternal grandfather, and

O

is the paternal grandmother of

Q

.

M

is the father of

N

(father's father = paternal grandfather).

O

is the mother-in-law of

P

, meaning

O

is the mother of

N

(father's mother = paternal grandmother).

3

Determine the relation of

R

R

is the grand-uncle (brother of paternal grandfather) of

Q

.

R

is the brother of

M

. Because

M

is the paternal grandfather of

Q

,

R

is the paternal grandfather's brother.

Question 25Question →

Read the following coded relationship definitions carefully:
- $P \div Q$ means ' $P$ is the mother of $Q$ '
- $P + Q$ means ' $P$ is the father of $Q$ '
- $P \times Q$ means ' $P$ is the brother of $Q$ '
- $P - Q$ means ' $P$ is the sister of $Q$ '

Based on the expression $J \div K + L \times M - N + O$ , how is $O$ related to $J$ ?

Great-grandson

Great-granddaughter

Paternal Great-grandmother

Cannot be determined

Show answer & explanation

Answer: Cannot be determined

Answer

Cannot be determined, as the gender of

O

is not specified in the given expression.

Tracing the expression shows that

J

is the mother of

K

,

K

is the father of

N

, and

N

is the father of

O

. This makes

J

the great-grandmother of

O

, which means

O

is the great-grandchild of

J

. Since

O

is the terminal node in

N + O

, no operation defines

O

's gender. Therefore,

O

could be either a great-grandson or a great-granddaughter, making the exact relationship impossible to determine.

Step-by-Step Solution

1

Decode the maternal and paternal lineage from the first part of the expression

J \div K

implies

J

is the mother of

K

.

K + L

implies

K

is the father of

L

.

Establishing the top two generations of the family lineage.

2

Determine the sibling relationships in the third generation

L \times M - N

indicates that

L

,

M

, and

N

are siblings (children of

K

). Specifically,

N

is a male child of

K

.

Identifying that

N

belongs to the third generation as

K

's son.

3

Analyze the relationship to the fourth generation and test for gender clarity

N + O

shows

N

is the father of

O

. Thus,

O

is the child of

N

, making

O

the great-grandchild of

J

. However, the gender of

O

is unstated.

Evaluating whether

O

's gender can be uniquely determined.

Question 26Question →

In a family of seven members— $P, Q, R, S, T, U,$ and $V$ —spanning three generations, there are two married couples. $P$ is the brother-in-law of $R$ , who is the only daughter of $U$ . $S$ is the father of $Q$ and $P$ . $T$ is the maternal grandmother of $V$ , and $Q$ is married to $R$ . If $V$ is a male child of $Q$ and $R$ , how is $V$ related to $U$ ?

Show answer & explanation

Answer: Grandson; Maternal grandson; Grand-son; Maternal Grandson

Answer

Grandson (or Maternal grandson)

Since R is the daughter of U and the mother of V, U is the grandfather of V. Because V is male, V is the grandson (or maternal grandson) of U.

Step-by-Step Solution

1

Determine the relation between R and Q, and identify their genders.

R is the daughter of U (female). Q is married to R, which means Q is male.

Marriage in standard family tree problems consists of one male and one female.

2

Identify the maternal lineage of V.

V is the child of Q (father) and R (mother), making R the mother of V.

Since T is the maternal grandmother of V, T is the mother of R, and U is the father of R.

3

Determine the relationship between V and U.

U is the maternal grandfather of V, making V the grandson (maternal grandson) of U.

V is the male child of U's daughter R.

Show answer & explanation

Answer

The correct pairings are:

P

matches with Maternal Grandfather;

R

matches with Maternal Uncle;

T

matches with Maternal Grandmother;

V

matches with Brother or Sister (Gender undetermined).

Each member is accurately mapped by tracing lineage through

S

's mother

Q

:

P

is the father of

Q

(Maternal Grandfather),

T

is the mother of

Q

(Maternal Grandmother),

R

is the brother of

Q

(Maternal Uncle), and

V

is a sibling of

S

whose gender is not explicitly stated.

Step-by-Step Solution

1

Determine the parental generation and married couples

Since

U

is a male married to

Q

, and

P

(father-in-law of

U

) is married to

T

,

P

(male) and

T

(female) are the parents of

Q

(female).

U

is male, so

Q

must be female.

P

is

U

's father-in-law, making

P

the father of

Q

and

T

the mother of

Q

.

2

Analyze the relationship of

P

,

T

, and

R

to

S

S

is the daughter of

Q

. Thus,

P

is maternal grandfather,

T

is maternal grandmother, and

R

(brother of

Q

) is maternal uncle to

S

.

Relationships through the mother's side of the family take the maternal prefix.

3

Analyze the relationship of

V

to

S

V

is a sibling of

S

, but gender is unknown.

Without explicit mention or deduction of gender,

V

's specific relation (brother vs sister) cannot be determined.

Kinship and In-Law Relationship Deduction

Question 29Question →

A demographic research algorithm maps family lineages using the following logical operators:

• $X \nabla Y$ means $X$ is the legally recognized spouse of $Y$ .
• $X \Delta Y$ means $X$ is the biological mother of $Y$ .
• $X \Omega Y$ means $X$ is the sibling of $Y$ .
• $X \Sigma Y$ means $X$ is the child of $Y$ .

Based strictly on the relational sequence $H \Sigma G \nabla F \Delta E \Omega D$ , which of the following conclusions is logically definitive?

H is the brother of E.

E is the sister of H.

G is the father of D.

D is the son of F.

Show answer & explanation

Answer: G is the father of D.

Answer

G is the father of D.

The sequence establishes that F is the mother of E, and E is the sibling of D, making F the mother of D as well. Because G is the spouse of F, G is definitively male and thus the father of F's children. Consequently, G is definitively the father of D.

Step-by-Step Solution

1

Analyze the relationship

F \Delta E

and

E \Omega D

.

F

is the mother of

E

, and

E

is the sibling of

D

. Therefore,

F

is also the mother of

D

.

To establish the maternal lineage for the right side of the sequence.

2

Analyze the relationship

G \nabla F

.

G

is the spouse of

F

. Since

F

is a mother (female),

G

must be male.

To determine the gender and parental role of

G

.

3

Combine the findings for

G

,

F

, and

D

.

G

is the husband of

F

, and

F

is the mother of

D

. Therefore,

G

is definitively the father of

D

.

To identify the exact relationship between the male spouse and the children.

4

Evaluate the genders of

H

,

E

, and

D

.

The operators

\Sigma

(child) and

\Omega

(sibling) do not assign a gender. Thus, the exact genders of

H

,

E

, and

D

remain unknown.

To eliminate any conclusions that make assumptions about unstated genders.
