Solving Blood Relations: Decoding the Expression

Blood relation questions test your ability to understand and decipher relationships presented in coded form. We are given a set of symbols, each representing a specific relationship. We need to apply these definitions to a given expression to find the relationship between two individuals.

Understanding the Code

Let's first list out the meaning of each symbol provided:

• % means 'is brother of'
• & means 'is the mother of'
• × means 'is the husband of'
• # means 'is sister of'
• $ means 'is the son of'
• @ means 'is the father of'

Analyzing the Given Expression

The expression is: A % D $ F # B % E × S

We will break down the expression segment by segment, from left to right, to determine the relationships.

1. A % D: According to the code, '%' means 'is brother of'. So, A is brother of D. This tells us A is male.
2. D $ F: According to the code, '$' means 'is the son of'. So, D is the son of F.
3. F # B: According to the code, '#' means 'is sister of'. So, F is sister of B. This tells us F is female.
4. B % E: According to the code, '%' means 'is brother of'. So, B is brother of E. This tells us B is male.
5. E × S: According to the code, '×' means 'is the husband of'. So, E is the husband of S. This tells us E is male and S is female.

Building the Family Tree

Now let's combine these individual relationships to establish the connections between the individuals:

• A is brother of D. (A and D are siblings. A is male.)
• D is son of F. Since D is male, F is a parent of D.
• F is sister of B. F is female. So F is the mother of D (and A, since A and D are siblings).
• F is sister of B, and B is brother of E. This means F, B, and E are siblings. F is female, B is male, and E is male.
• E is husband of S.

Let's summarize the key connections relevant to A and E:

• A is the son of F.
• F is the sister of B.
• B is the brother of E.

Since F is the sister of B and B is the brother of E, it implies that F, B, and E are siblings. F is female, B is male, E is male.

Now, let's connect A to E:

• A is the son of F.
• F is the sister of E (since F, B, and E are siblings and F is female).

So, A is the son of E's sister. The son of one's sister is a nephew.

A is male, which fits the role of a nephew.

Therefore, A is the nephew of E.

Determining the Relationship of A to E

From our analysis:

• A is son of F.
• F is sister of B.
• B is brother of E.

Since F is sister of B and B is brother of E, F is also sister of E.

So, A is the son of F, and F is E's sister.

This means A is the son of E's sister.

The relationship of A to E is that A is E's nephew.

Conclusion

Based on the step-by-step decoding of the blood relation expression, we determined that A is the son of E's sister, making A the nephew of E.

Additional Information on Blood Relations Reasoning

Blood relations questions often appear in competitive exams. They can be presented in various forms:

• Coded Relations: Like the problem above, where symbols represent relationships.
• Dialogue/Conversation Based: A person points to another and describes a relationship.
• Puzzle Based: A set of statements about family members from which you deduce relationships.

Tips for solving blood relation problems:

• Carefully read the code or statements.
• Draw a family tree diagram. Use symbols for gender (e.g., + for male, - for female) and relationships (e.g., double line for marriage, single line for siblings, downward line for parent-child).
• Break down complex statements into simpler steps.
• Identify the genders of individuals whenever possible, as this is often crucial.
• Work from the known relationship towards the unknown one.
• Practice different types of questions to improve speed and accuracy.

Understanding common relationships like grandparent, parent, child, sibling, uncle, aunt, nephew, niece, cousin is essential.
