Understanding Blood Relations and Symbols

This question involves understanding relationships defined by specific symbols. We are given three rules that define the relationships between two people, denoted by A and B:

• A @ B means A is the husband of B.
• A & B means A is the mother of B.
• A # B means A is the daughter of B.

We need to use these rules to decode a longer expression and determine the relationship between two individuals mentioned in it.

Decoding the Given Expression

The expression given is G @ V & K @ P # J. We need to break this down into smaller parts based on the symbols:

1. G @ V
2. V & K
3. K @ P
4. P # J

Let's decode each part using the given rules:

• G @ V: Using the rule A @ B means A is the husband of B, this means G is the husband of V. This tells us G is male and V is female. Since G is the husband of V, V is the wife of G.
• V & K: Using the rule A & B means A is the mother of B, this means V is the mother of K. We already know V is female. This tells us V has a child named K.
• K @ P: Using the rule A @ B means A is the husband of B, this means K is the husband of P. This tells us K is male and P is female. Since K is the husband of P, P is the wife of K.
• P # J: Using the rule A # B means A is the daughter of B, this means P is the daughter of J. We already know P is female. This tells us J is the parent of P (either father or mother, the gender of J is not determined by this relationship alone).

Determining the Relationship: G and P

Now let's combine these relationships to find out how G is related to P:

• From G @ V, G is the husband of V.
• From V & K, V is the mother of K.
• Since G is V's husband and V is K's mother, G must be the father of K.
• From K @ P, K is the husband of P.

We know G is the father of K, and K is the husband of P. This means K is G's son. P is married to K. Therefore, P is the wife of G's son.

The father of one's son's wife is the father-in-law.

So, G is the father-in-law of P.

Step-by-Step Blood Relation Solution

Let's list the derived relationships and trace the path from G to P:

1. G is the husband of V (from G @ V).
2. V is the mother of K (from V & K).
3. Combining 1 and 2: G is the father of K.
4. K is the husband of P (from K @ P).
5. Combining 3 and 4: G is the father of K, and K is the husband of P. Therefore, P is the wife of G's son.
6. The father of one's son's wife is the father-in-law.

Thus, G is the father-in-law of P.

We can also represent this structure:

Putting it together: G (Male) is married to V (Female). V is the mother of K (Male, from K @ P). So, G is the father of K. K (Male) is married to P (Female). Therefore, G is the father of K, who is married to P. G is P's husband's father, which means G is P's father-in-law.

Revision Table: Key Relationships

Additional Information: Blood Relation Concepts

Blood relation questions test your ability to decode relationships and trace connections within a family tree. Key concepts include:

• Generations: Understanding who belongs to which generation (e.g., parents, children, grandparents, grandchildren).
• Gender Identification: Determining the gender of individuals based on the relationship descriptions (e.g., husband is male, mother is female, daughter is female).
• Tracing Paths: Following the sequence of relationships provided in the expression to link the individuals in question.
• In-laws: Understanding relationships created by marriage, such as father-in-law, mother-in-law, son-in-law, daughter-in-law, brother-in-law, sister-in-law.

Practice with different types of symbolic representations and longer expressions can help improve speed and accuracy in solving blood relation problems.
