Solving Blood Relation Code Questions

This question asks us to determine the relationship between two individuals, K and R, based on a given expression involving coded relationships. We need to decode the symbols and build the family structure step by step.

Understanding the Code Language

The problem provides a simple code language for blood relations:

• A % B means A is the father of B.
• A # B means A is the brother of B.
• A $ B means A is the wife of B.

Analyzing the Expression: K $ H % Y # M # R

Let's break down the given expression part by part:

1. K $ H: According to the code, A $ B means A is the wife of B. So, K is the wife of H. This tells us K is female and H is male. K and H are a married couple.
2. H % Y: According to the code, A % B means A is the father of B. So, H is the father of Y. This means Y is a child of H. Since K is the wife of H, K is the mother of Y.
3. Y # M: According to the code, A # B means A is the brother of B. So, Y is the brother of M. This tells us Y is male. Y and M are siblings, and Y is older than M or simply a male sibling. Since Y is a child of H and K, M is also a child of H and K.
4. M # R: According to the code, A # B means A is the brother of B. So, M is the brother of R. This tells us M is male. M and R are siblings. Since M is a child of H and K, R is also a child of H and K.

Building the Family Structure

From the analysis above, we can piece together the family relationships:

• K is the wife of H.
• H is the father of Y.
• Y is the brother of M.
• M is the brother of R.

This implies that H and K are the parents, and Y, M, and R are their children (siblings). K is the mother and H is the father of Y, M, and R.

Determining the Relationship of K to R

Based on the family structure derived:

• K and H are parents of Y, M, and R.
• K is the mother.
• H is the father.

The question asks how K is related to R. Since R is a child of K and H, and K is the mother, K is the mother of R.

Therefore, K is the Mother of R.

Additional Information: Types of Blood Relations

Blood relation questions test your ability to decode relationships and construct a family tree. Relationships can be broadly categorized:

• Paternal Relations: Relations on the father's side (father, grandfather, grandmother, uncle, aunt, etc.)
• Maternal Relations: Relations on the mother's side (mother, grandfather, grandmother, uncle, aunt, etc.)
• Marital Relations: Relations through marriage (husband, wife, in-laws).
• Sibling Relations: Brothers and sisters.
• Children/Grandchildren: Direct descendants.

Carefully decoding each part of the expression and assigning genders where possible is key to solving these problems accurately. Drawing a diagram can often help visualize the relationships.
