Understanding Blood Relation Coding

This question involves decoding a set of relationships represented by specific symbols in a code language. We are given the meaning of four symbols and an expression involving these symbols and letters representing people. Our task is to determine the relationship between two specific individuals mentioned in the expression based on the decoded relationships.

Decoding the Symbols in Blood Relations

First, let's list the given codes and their meanings:

• P - Q means 'P is the wife of Q'
• P $\div$ Q means 'P is the husband of Q'
• P $\times$ Q means 'P is the son of Q'
• P + Q means 'P is the daughter of Q'

Analyzing the Given Expression: H - I $\times$ J $\div$ K + G

Now, let's break down the given expression segment by segment using the decoded meanings. We will determine the relationship between adjacent pairs of letters:

• H - I: Using the rule 'P - Q means P is the wife of Q', H - I means 'H is the wife of I'. This tells us H is female, I is male, and they are married.
• I $\times$ J: Using the rule 'P $\times$ Q means P is the son of Q', I $\times$ J means 'I is the son of J'. This confirms I is male (which we already knew) and J is I's parent.
• J $\div$ K: Using the rule 'P $\div$ Q means P is the husband of Q', J $\div$ K means 'J is the husband of K'. This tells us J is male, K is female, and they are married. Since I is the son of J, and J is married to K, K must be I's mother. Also, J is I's father.
• K + G: Using the rule 'P + Q means P is the daughter of Q', K + G means 'K is the daughter of G'. This tells us K is female (which we already knew) and G is K's parent.

Establishing the Family Connections

Let's summarize the relationships we've found, focusing on the path from G to I:

1. K + G means K is the daughter of G. So, G is the parent of K.
2. J $\div$ K means J is the husband of K.
3. I $\times$ J means I is the son of J.

Combining these relationships:

• K is G's daughter.
• J is K's husband (which means J is G's son-in-law).
• I is J's son.

We need to find out how I is related to G.

• We know K is G's daughter.
• We know K is married to J, and I is J's son.
• Since K is married to J and I is J's son, K is I's mother and J is I's father.
• So, I is the son of K, and K is G's daughter.
• Therefore, I is the son of G's daughter.

This makes I the 'Daughter's son' of G.

Checking the Options

Let's compare our findings with the given options:

Based on our analysis, the relationship "Daughter's son" accurately describes how I is related to G.

Conclusion on Blood Relation Puzzle

By carefully decoding each part of the expression H - I $\times$ J $\div$ K + G using the provided code language for blood relations, we determined the familial connections between all individuals. Following the chain of relationships, we found that I is the son of K, who is the daughter of G. Thus, I is G's daughter's son.

Additional Information on Coded Blood Relations

Coded blood relation questions are common in reasoning sections of competitive exams. They test your ability to decode information and build a logical family tree or relationship map. Key strategies include:

• Identifying the gender of individuals where possible based on the relationship (e.g., wife is female, husband is male, son is male, daughter is female).
• Building the relationship chain step-by-step from left to right or right to left based on the expression.
• Representing the family structure visually can sometimes help, but for simpler expressions like this, tracing the relationships linearly is sufficient.
• Pay close attention to who is related to whom (A is the relation of B vs. B is the relation of A). The question asks how I is related to G, not the other way around.

Practicing different types of coded relationships and longer expressions helps improve speed and accuracy in solving these puzzles.
