Understanding Blood Relation Codes

This question asks us to determine the relationship between two individuals, N and F, based on a coded expression. We are given a set of codes representing different family relationships:

  • ‘A # B’ means ‘A is the brother of B’ (A is male).
  • ‘A @ B’ means ‘A is the daughter of B’ (A is female).
  • ‘A & B’ means ‘A is the husband of B’ (A is male, B is female).
  • ‘A % B’ means ‘A is the wife of B’ (A is female, B is male).

We need to decode the expression ‘D @ N @ H & Y @ F % V’ step by step to build a family tree and find the relationship between N and F.

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

Let's break down the given expression from right to left or left to right, linking the relationships:

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

Building the Family Tree

Based on the decoded relationships, we can construct the family tree:

  • F % V means F is the wife of V. So, F and V are a married couple, with F being female and V being male.
  • Y @ F means Y is the daughter of F. Since F is married to V, Y is the daughter of both F and V. (Y is female)
  • H & Y means H is the husband of Y. So, H is married to Y. (H is male)
  • N @ H means N is the daughter of H. Since H is married to Y, N is the daughter of both H and Y. (N is female)
  • D @ N means D is the daughter of N. (D is female)

Let's visualize the connections:

V (Male) ---married to--- F (Female)

                        | <-- child

                         Y (Female)

                         | ---married to--- H (Male)

                         | <-- child

                         N (Female)

                         | <-- child

                         D (Female)

Determining the Relationship between N and F

We want to find out how N is related to F.

From our family tree:

  • Y is the daughter of F.
  • N is the daughter of Y.

Since N is the daughter of Y, and Y is the daughter of F, N is the daughter of F's daughter.

Conclusion

The relationship between N and F is that N is the daughter's daughter of F.

Expression Segment Relationship Implied Gender
F % V F is wife of V F (Female), V (Male)
Y @ F Y is daughter of F Y (Female)
H & Y H is husband of Y H (Male)
N @ H N is daughter of H N (Female)
D @ N D is daughter of N D (Female)

Therefore, tracing the lineage from F to N: F is the parent of Y, and Y is the parent of N. Specifically, Y is F's daughter, and N is Y's daughter. This makes N the daughter of F's daughter.

Code Meaning A's Gender B's Gender
A # B A is brother of B Male Can be Male/Female
A @ B A is daughter of B Female Can be Male/Female
A & B A is husband of B Male Female
A % B A is wife of B Female Male

Additional Information: Solving Blood Relation Puzzles

Solving blood relation questions with coded relationships involves careful step-by-step decoding and often building a visual family tree or diagram. Here are some tips:

  • Identify the gender of individuals based on the codes. Some codes, like 'husband' or 'wife', define both genders in the pair, while others, like 'brother' or 'daughter', only define the first person's gender.
  • Break down the expression into smaller segments.
  • Link the segments to connect individuals. For example, if A @ B and B # C, you know A is B's daughter and B is C's brother. This connects A and C.
  • Draw a diagram or tree structure to represent the relationships. Use symbols like circles for females, squares for males, double lines for marriage, and single lines for parent-child or sibling relationships.
  • Trace the relationship path between the two individuals mentioned in the question.
  • Practice with different types of codes and expressions to improve speed and accuracy.
