Understanding Blood Relation Coding Questions

Blood relation questions in logical reasoning involve decoding relationships based on a given set of codes or symbols. To solve these, we need to break down the given expression step by step and build a family tree or chain of relationships.

Decoding the Relationship Codes

The question provides the following codes for relationships:

• A + B means 'A is the father of B'
• A - B means 'A is the wife of B'
• A × B means 'A is the brother of B'
• A ÷ B means 'A is the mother of B'

Analyzing the Expression 'G ÷ H × I - J + K'

Let's break down the given expression segment by segment to understand the relationships between G and K.

The expression is: G ÷ H × I - J + K

1. G ÷ H:

   According to the code, A ÷ B means 'A is the mother of B'.

   So, G is the mother of H. (Gender of G is Female)

2. H × I:

   According to the code, A × B means 'A is the brother of B'.

   So, H is the brother of I. (Gender of H is Male)

   Since G is the mother of H, and H is the brother of I, G is also the mother of I. H and I are siblings.

3. I - J:

   According to the code, A - B means 'A is the wife of B'.

   So, I is the wife of J. (Gender of I is Female, Gender of J is Male)

   Since I is the wife of J, J is the husband of I.

4. J + K:

   According to the code, A + B means 'A is the father of B'.

   So, J is the father of K. (Gender of J is Male)

Tracing the Relationship from G to K

Now let's connect the relationships we've found:

• G is the mother of H.
• H is the brother of I.
• Therefore, G is also the mother of I.
• I is the wife of J.
• J is the father of K.
• Since I is the wife of J and J is the father of K, I is the mother of K.

We have established that:

• G is the mother of I.
• I is the mother of K.

This means G is the mother of K's mother. Therefore, G is the mother's mother of K.

Summary of Relationships

Combining the deductions, G is the mother of I, and I is the mother of K. Thus, G is K's mother's mother.

Conclusion

Based on the decoding of the expression 'G ÷ H × I - J + K', the relationship between G and K is that G is the mother's mother of K.

Additional Information: Solving Blood Relation Puzzles

Solving blood relation puzzles effectively requires a systematic approach:

• Understand the Codes: Carefully note down what each symbol or term represents in terms of relationships and gender.
• Break Down the Expression: Analyse the given coded expression segment by segment from left to right.
• Build a Family Tree/Diagram: Draw a simple diagram to represent the relationships as you decode them. Use symbols for gender (e.g., + for male, - for female) and arrows to show the direction of the relationship (e.g., parent to child).
• Note Gender Information: Pay close attention to information that reveals the gender of individuals, as this is often crucial for determining the final relationship.
• Connect the Links: Trace the path between the two individuals whose relationship you need to find by following the connections in your diagram or deduced relationships.
• Verify: Reread the question and your deduced relationships to ensure accuracy.

Practicing different types of blood relation questions with various coding patterns can help improve speed and accuracy for competitive exams.
