Blood Relation related questions are one of the sure-shot questions in the Reasoning part. Every banking related exams and other government competitive exams include this topic.

So, keeping all these in mind, we are providing the PDF questions for Blood Relation topics, along with some solved examples.
Check the basic concepts, question types, and some tips to solve the questions. Generally, we can find three types of questions-pointed/dialogue type, short puzzles, and symbolically coded questions.
- Pointed or dialogue type question, candidates have to find the relation of persons in the question, from the relationships between other persons given in the question.
- Puzzles may be twisting and a little bit confusing, or sometimes easy ones connecting a large number of people. Candidates can draw relations and easily find the answer.
- Symbolically coded blood relation questions will have certain codes for each relation. Firstly, we have to find relations, then make a diagram and answer the question.
Representation of Relations-Family Tree Method
Hierarchy based on seven generations in blood relations questions is:
|Three generations above↑↑↑||Great grandfather Maternal great grandfather Great grandfather-in-law||Great grandmother Maternal great grandmother Great grandmother-in-law|
|Two generations above ↑↑||Grandfather Maternal grandfather Grandfather-in-law||Grandmother Maternal grandmother Grandmother-in-law|

Worked out Examples:
Dialogue or pointed:
1. If P’s the father is Q, R is the father of Q and S is P’s mother, how is R related to S?
We can represent males by + and females by -, siblings by —, and married relations by =, next-generation by a |. Also don’t guess the gender, if it is not specified in the question, leave it for cannot be determined.
2. Pointing to a photograph of a person, Mr.Akhil said, “He is the son of the only son of my mother.” How is Mr. Akhil related to that person?
Solution: Father. This is again a pointing type question. Let us check,
3. If P+Q means P is the daughter of Q; P-Q means P is the husband of Q; P*Q means P is the brother of Q.
If A+B-C, which of the following is true?
a) C is the mother of A
b) C is the sister in law of A
c) Cannot be determined
d) C is the aunt of A
4. A is the father of B. B is the only son of C. C is the daughter of D. C is the mother of E. E is the sister of F. Then how is F related to A?
d) Cannot be determined
Even though the gender of F is not specified, it is given that B is the “only son” of C. So, F will be the daughter of A.
