Solving Blood Relations: Finding the Relationship Between E and I

This question involves decoding relationships based on given symbols. We need to analyze the expression step-by-step to build the family tree and determine how E is related to I.

Understanding the Relationship Codes

Let's first understand the meaning of each symbol given in the problem:

• P × Q means P is the wife of Q.
• P + Q means P is the father of Q.
• P ÷ Q means P is the daughter of Q.
• P - Q means P is the son of Q.

Analyzing the Expression: E ÷ F + G - H ÷ I

We will break down the given expression part by part from left to right to determine the relationships:

1. E ÷ F: According to the code, 'P ÷ Q' means 'P is the daughter of Q'. So, E is the daughter of F. This tells us E is female, and F is a parent of E.
2. F + G: According to the code, 'P + Q' means 'P is the father of Q'. So, F is the father of G. This tells us F is male, and G is a child of F.
3. Combining the first two parts (E ÷ F and F + G): E is the daughter of F, and F is the father of G. This means E and G are siblings, both being children of F. E is female, and F is male.
4. G - H: According to the code, 'P - Q' means 'P is the son of Q'. So, G is the son of H. This tells us G is male, and H is a parent of G.
5. Combining the parts so far (E ÷ F, F + G, and G - H): E is the daughter of F, F is the father of G, and G is the son of H.
   • We know F is the father of G, and G is the son of H. This implies that H must be the other parent of G, i.e., the mother of G.
   • Since F is the father and H is the mother of the same child (G), F and H are a married couple, where F is the husband and H is the wife.
   • We also know E is the daughter of F. Since F and H are married, E is also the daughter of H.
   • So, E and G are siblings, children of both F (father) and H (mother). E is female, and G is male.
6. H ÷ I: According to the code, 'P ÷ Q' means 'P is the daughter of Q'. So, H is the daughter of I. This tells us H is female, and I is a parent of H.

Establishing the Relationship Between E and I

Let's connect the relationships we have deduced:

• E is the daughter of H (from step 5).
• H is the daughter of I (from step 6).

If H is the daughter of I, then I is the parent of H (either father or mother). Since E is the daughter of H, who is herself the daughter of I, E is two generations below I.

Specifically, E is the child of H, and H is the child of I. This makes E the grandchild of I. Since E is female (as determined in step 1 and 5), E is the granddaughter of I.

Summary of Relationships

Putting it together:

• F is father of G and parent of E. F is male.
• G is son of H and child of F. G is male.
• H is parent of G and parent of E. H is daughter of I. H is female.
• E is daughter of F and daughter of H. E is female.
• I is parent of H.

So, H is the daughter of I, and E is the daughter of H. Therefore, E is the granddaughter of I.

Additional Information on Blood Relation Questions

Blood relation questions in reasoning tests often involve decoding relationships from symbols or descriptions. The key is to build a clear picture, often a family tree, step by step. Always pay close attention to the gender of each person when it is specified, as it is crucial for determining the exact relationship (e.g., son vs. daughter, grandmother vs. grandfather, grandson vs. granddaughter).

Practice different types of coding and relationship descriptions to improve your ability to quickly and accurately trace the connections between individuals mentioned in the problem. Breaking down complex expressions into smaller, manageable parts is a very effective strategy.
