Solving Blood Relation Questions
Blood relation questions involve understanding the relationships between different members of a family. To solve these problems, it's helpful to build a family tree or list the relationships given in the statements.
Analyzing the Given Relationships
Let's break down the information provided step by step:
- "C is the son of A". This tells us A is the parent of C, and C is male.
- "A is not the mother of C". Since C is the son of A, and A is not the mother, A must be the father of C. So, A is male.
- "D and C are a married couple". This means D and C are spouses. Since C is male, D must be female (wife of C).
- "E is the brother of C". This means E and C are siblings, and E is male.
- "F is the daughter of D". This means D is the parent of F, and F is female. Since D is married to C, and D is the mother of F, C must be the father of F.
- "G is the brother of A". This means G and A are siblings, and G is male.
Constructing the Family Linkages
Based on the analysis, we can establish the following connections:
- A (Father) <--> C (Son)
- C (Husband) <--> D (Wife)
- E (Brother) <--> C (Brother)
- D (Mother) <--> F (Daughter)
- C (Father) <--> F (Daughter) (Implied from C being married to D, the mother of F)
- A (Brother) <--> G (Brother)
So, C is the father of F, and D is the mother of F.
Determining the Relationship between E and F
We need to find how E is related to F.
We know that:
- E is the brother of C.
- C is the father of F.
If C is the father of F, then E, being the brother of C, is the brother of F's father.
The brother of one's father is known as one's Uncle.
Therefore, E is the Uncle of F.
Checking the Options
Let's look at the given options:
- Uncle
- Father
- Sister-in-law
- Brother
Our derived relationship is Uncle, which matches Option 1.
Detailed Relationship Derivation Table
| Statement | Inference | Relationship |
|---|---|---|
| C is son of A; A is not mother of C | A is Father of C | A(+), C(+) |
| D and C are married couple | D is Wife of C | C(+) <-> D(-) |
| E is brother of C | E is sibling of C | E(+) |
| F is daughter of D | D is Mother of F | D(-) <-> F(-) |
| (From D & C married, D mother of F) | C is Father of F | C(+) <-> F(-) |
| E is brother of C; C is father of F | E is brother of F's father | E is Uncle of F |
Thus, E is the uncle of F.

Additional Information on Solving Blood Relation Puzzles
Solving blood relation puzzles effectively requires careful reading and step-by-step deduction. Visual aids like family trees can be very helpful. Assigning symbols for gender (e.g., + for male, - for female) and relationships (e.g., double arrow for marriage, single arrow for parent-child, horizontal line for siblings) can simplify complex problems.
Always start with the most direct relationships given and build outwards. Sometimes, combining two statements reveals a crucial link that helps solve the puzzle. Pay close attention to words like 'son', 'daughter', 'brother', 'sister', 'husband', 'wife', 'father', 'mother', as they define the specific type of relationship and gender.
Consider all possibilities that fit the initial statements before making a final conclusion. Practice with different types of blood relation questions to improve speed and accuracy.
