Understanding Blood Relation Symbols

In blood relation questions, specific symbols are used to represent different relationships between individuals. It is crucial to first understand what each symbol signifies.

  • ‘A @ B’ means ‘A is the husband of B’. This implies B is the wife of A.
  • ‘A & B’ means ‘A is the mother of B’. This implies B is the child of A.
  • ‘A # B’ means ‘B is the daughter of A’. This implies A is the parent of B, and B is female.

Decoding the Blood Relation Expression: G # H & I @ J & K

Let's break down the given expression step by step to determine the relationships:

The expression is: G # H & I @ J & K

We analyze it segment by segment:

  1. G # H: Using the rule ‘A # B’ means ‘B is the daughter of A’, this means ‘H is the daughter of G’. From this, we know H is female, and G is her parent (either father or mother).
  2. H & I: Using the rule ‘A & B’ means ‘A is the mother of B’, this means ‘H is the mother of I’. Since H is the mother of I, we confirm H is female, which matches the previous step. I is the child of H.
  3. I @ J: Using the rule ‘A @ B’ means ‘A is the husband of B’, this means ‘I is the husband of J’. From this, we know I is male, and J is his wife (female).
  4. J & K: Using the rule ‘A & B’ means ‘A is the mother of B’, this means ‘J is the mother of K’. From this, we know K is the child of J. Since J is the wife of I, K is also the child of I.

Determining the Relationship: H to J

We want to find out how H is related to J based on the decoded relationships:

  • From step 2, we know that H is the mother of I.
  • From step 3, we know that I is the husband of J.

Combining these two facts:

H is the mother of I, and I is the husband of J. This means H is the mother of J's husband.

The mother of one's husband is known as the Mother-in-law.

Therefore, H is the mother-in-law of J.

Final Answer Relationship

Based on the analysis of the given expression and symbols, H is related to J as her mother-in-law.

Additional Information: Understanding Blood Relation Concepts

Blood relation problems often require you to build a family tree or diagram based on the given coded relationships. Key concepts include:

  • Generations: Identifying individuals belonging to the same generation (siblings, cousins), the generation above (parents, aunts, uncles), or the generation below (children, nephews, nieces).
  • Gender Identification: Determining the gender of each individual based on the relationship definitions. For example, 'husband' implies male, 'wife' implies female, 'mother' implies female, 'father' implies male, 'son' implies male, 'daughter' implies female. Some relationships like 'parent' or 'child' might not initially specify gender unless stated otherwise or deduced from other relations.
  • Tracing the Path: To find the relationship between two individuals, trace the connections through the chain of relationships provided in the expression.
  • In-law Relationships: These relationships are formed through marriage (e.g., mother-in-law, father-in-law, brother-in-law, sister-in-law).

Practicing various types of blood relation puzzles helps in quickly decoding the symbols and tracing the relationships accurately.
