Understanding Blood Relations Questions

Blood relations questions test your ability to understand and decipher family relationships based on given codes or symbols. In this type of question, specific symbols represent relationships like daughter, sister, husband, etc. You need to use these definitions to trace the relationship between two individuals mentioned in the question.

Decoding the Symbols

The question provides the meaning of three symbols:

• G + H means G is daughter of H. (This tells us G is female.)
• G - H means G is sister of H. (This tells us G is female.)
• G * H means G is husband of H. (This tells us G is male and H is female.)

The Goal: Finding I as Daughter of H

We are looking for the option that correctly represents the relationship where I is the daughter of H. This means two things must be true:

1. I must be female.
2. H must be a parent of I (either mother or father).

Analyzing Each Option to Trace the Relationship

Let's break down each option symbol by symbol to find the relationship between I and H.

Option 1: I – J + F * H

We trace the relationships starting from the left:

• I – J: According to the rule 'G - H means G is sister of H', this means I is the sister of J. (This tells us I is female).
• J + F: According to the rule 'G + H means G is daughter of H', this means J is the daughter of F. (This tells us J is female and F is a parent of J).
• F * H: According to the rule 'G * H means G is husband of H', this means F is the husband of H. (This tells us F is male and H is female. F and H are married).

Combining the relationships:

• I is the sister of J.
• J is the daughter of F.
  Since I and J are siblings, and J is the daughter of F, I must also be the daughter of F.
• F is the husband of H.
  Since F is the father of I (from the previous step) and F is married to H, H must be the mother of I.

Therefore, Option 1 shows that I is the daughter of H.

Option 2: I + J - F * H

Tracing the relationships:

• I + J: I is the daughter of J. (I is female. J is a parent of I).
• J - F: J is the sister of F. (J is female).
• F * H: F is the husband of H. (F is male, H is female).

Combining the relationships:

• I is the daughter of J.
• J is the sister of F.
  So, I's mother (or father) is J, and J's sibling is F. This makes F the uncle or aunt of I.
• F is the husband of H.
  F is I's uncle/aunt, and F is married to H. If F is I's uncle (J's brother), then H is I's aunt by marriage (uncle's wife). If F is I's aunt (J's sister), this contradicts F * H where F is male. Since J is female and sister of F, F must be male or female. F*H tells us F is male. So F is J's brother (I's uncle) and H is F's wife (I's aunt by marriage).

This option shows H is related to I as an aunt by marriage, not as a parent. Therefore, Option 2 does not show I is the daughter of H.

Option 3: I – J * F + H

Tracing the relationships:

• I – J: I is the sister of J. (I is female).
• J * F: J is the husband of F. (J is male, F is female).
• F + H: F is the daughter of H. (F is female. H is a parent of F).

Combining the relationships:

• I is the sister of J.
• J is the husband of F.
  So I is the sister of F's husband.
• F is the daughter of H.
  H is the parent of F. F is married to J, and I is J's sister. So H is the parent of F, and F is married to I's brother-in-law. H is the parent of F. F is married to J. I is sister of J. Thus, H is the parent of F, who is married to the brother of I. H is the mother or father of F, and thus H is mother-in-law or father-in-law of J. Since I is J's sister, H is the mother or father of I's sister-in-law.

This option shows H is a parent of F, who is married to I's brother. This does not show I is the daughter of H.

Option 4: I * J - F + H

Tracing the relationships:

• I * J: I is the husband of J. (I is male, J is female).
• J - F: J is the sister of F. (J is female).
• F + H: F is the daughter of H. (F is female. H is a parent of F).

Combining the relationships:

• I is the husband of J.
• J is the sister of F.
  So, I's wife is J, and J's sister is F. F is I's sister-in-law.
• F is the daughter of H.
  F is I's sister-in-law, and F is the daughter of H. Since F is the daughter of H, and J is the sister of F, J is also the daughter of H. Since J is the daughter of H, and I is the husband of J, H is the parent of I's wife. H is I's parent-in-law.

This option shows H is the parent of J, and I is married to J. This does not show I is the daughter of H. Also, the first relation I * J establishes I as male, which contradicts the target of I being a daughter (female).

Summary of Relationships

Let's summarize the relationship between I and H derived from each option:

Based on the step-by-step analysis, only Option 1 results in I being the daughter of H.

Additional Information: Solving Blood Relation Puzzles

Solving blood relation puzzles effectively involves a few key strategies:

• Read the symbol definitions carefully and maybe jot them down.
• Start tracing the relationship from one end of the expression towards the other.
• Pay close attention to the gender implied by each relationship symbol. This can help eliminate options quickly if the required gender doesn't match.
• Mentally or physically draw a small family tree if the relationships become complex.
• Break down complex expressions into smaller, manageable pairs (e.g., A*B-C+D becomes A*B, then (A*B)-C, then ((A*B)-C)+D).
• Always double-check the final derived relationship against the target relationship asked in the question.

Practice with different types of blood relation coding questions will improve your speed and accuracy.
