Solving the Blood Relation Question

This question involves understanding and tracing relationships within a family structure. We are given several relationships and need to determine how two specific individuals, A and D, are related.

Understanding the Given Relationships

Let's break down the relationships provided:

A is B's sister. This means A and B are siblings.
C is B's mother. If C is B's mother, and A is B's sister, then C is also A's mother.
D is C's father. This tells us D is the father of A's mother.
E is D's mother. This relationship involves E, but it is not directly needed to find the relationship between A and D.

Tracing the Relationship between A and D

We want to find out how A is related to D. Let's use the connections we've identified:

We know C is A's mother.
We know D is C's father.
Combining these, D is the father of A's mother.

The father of one's mother is their maternal grandfather. Therefore, D is the maternal grandfather of A.

The question asks how A is related to D. If D is A's grandfather, then A must be D's granddaughter.

Conclusion

Based on the step-by-step analysis of the relationships:

C is A's mother.
D is C's father.
So, D is A's mother's father.
This makes D A's grandfather.
Therefore, A is D's granddaughter.

Individual	Relationship	Inferred Relationship to A
B	Sibling of A	-
C	Mother of B	Mother of A (since A & B are siblings)
D	Father of C	Father of A's Mother (Grandfather of A)
E	Mother of D	Great-Grandmother of A (not directly relevant to the question)

Thus, A is the granddaughter of D.

Additional Information on Solving Blood Relation Problems

Blood relation questions test your ability to understand family relationships and trace connections logically. Here are some tips for solving them:

Draw a Diagram: Creating a family tree diagram can be very helpful. Use symbols for gender (e.g., circle for female, square for male) and lines to connect generations and relationships (e.g., horizontal line for siblings/spouse, vertical line for parent-child).
Break Down Sentences: Read each statement carefully and understand the direct relationship it describes.
Connect the Dots: Start from one person mentioned in the question and link them to others based on the given relationships until you reach the person whose relationship you need to find.
Determine Gender: Pay attention to words like sister, brother, mother, father, son, daughter, etc., as they indicate gender, which is often crucial. Sometimes, the name itself might indicate gender, but rely primarily on the relationship terms unless specified.
Identify Generations: Understand which individuals belong to the same generation (siblings, cousins, spouse) and which belong to different generations (parents, grandparents, children, grandchildren).
