Understanding Family Relationships from Symbolic Codes

This question requires us to decode a series of symbolic relationships and determine the connection between two individuals based on the given expression.

Decoding the Symbols

Let's first understand what each symbol represents:

• ‘A # B’ means ‘A is the brother of B’.
• ‘A @ B’ means ‘A is the daughter of B’.
• ‘A & B’ means ‘A is the husband of B’.
• ‘A % B’ means ‘A is the wife of B’.

Analyzing the Expression: D @ N @ H & Y @ F % V

We need to break down the given expression step-by-step to build the family tree or list the relationships:

1. D @ N: This means D is the daughter of N. (D is female)
2. N @ H: This means N is the daughter of H. (N is female)
3. H & Y: This means H is the husband of Y. (H is male, Y is female)
4. Y @ F: This means Y is the daughter of F. (Y is female)
5. F % V: This means F is the wife of V. (F is female, V is male)

Establishing Connections and Finding the Relationship between Y and D

Let's connect the relationships starting from D:

• D is the daughter of N.
• N is the daughter of H. This means H is the parent of N. Since D is N's daughter, D is H's granddaughter.
• H is the husband of Y. This means Y is the wife of H. So, H and Y are a married couple.
• Since N is the daughter of H, and H is married to Y, N is also the daughter of Y.
• Now we know: D is the daughter of N, and N is the daughter of Y.

From these steps, we can see the direct line of descent from Y to D:

Y (parent of N) → N (parent of D) → D

Since Y is the mother of N (because N is daughter of H and H is husband of Y), and N is the mother of D (because D is daughter of N), Y is the mother of N, who is the mother of D.

Therefore, Y is the mother's mother of D, which means Y is the grandmother of D.

Considering the Other Parts of the Expression

The parts Y @ F and F % V tell us about Y's parents (Y is daughter of F, F is wife of V, so F and V are Y's parents). This information confirms Y's position in her own family but does not change the relationship we derived between Y and D based on the chain D ← N ← (H & Y).

Conclusion

Based on the step-by-step decoding of the expression D @ N @ H & Y @ F % V, we found that Y is the mother of N, and N is the mother of D. Thus, Y is the mother's mother of D.

Matching with Options

Let's compare our derived relationship with the given options:

1. Mother - Incorrect. Y is N's mother, not D's.
2. Husband’s mother - Incorrect. There is no husband relationship specified for D directly leading to Y.
3. Father’s sister - Incorrect. This implies Y is D's aunt through D's father, but we established the connection through D's mother (N).
4. Mother’s mother - Correct. Y is the mother of D's mother (N).

Additional Information on Blood Relations

Blood relation questions test your ability to understand and decode family connections. These problems often involve symbolic representations, direct statements, or complex descriptions. The key is to build a clear family tree or diagram the relationships as you decode the information. Pay close attention to gender and generational levels.

• Generations: Understanding terms like parent, child, grandparent, grandchild, uncle, aunt, nephew, niece is crucial.
• Gender: Note the gender of each individual if specified or implied by the relationship (e.g., husband implies male, wife implies female, brother implies male, sister implies female).
• Connecting Links: Look for common individuals who link different parts of the relationship chain.
• Practice: Solving various types of blood relation puzzles helps improve speed and accuracy.
