UNIT 10 – BLOOD RELATIONS
Introduction:
The questions which are asked in this section depend upon Relation.
You should have a sound knowledge of the blood relation in order to
solve the questions.
To remember easily the relations may be divided into two sides as
given below:
Relations of Paternal side:

2. Father's mother → Grandmother
3. Father's brother → Uncle
4. Father's sister → Aunt
5. Children of uncle → Cousin
6. Wife of uncle → Aunt
7. Children of aunt → Cousin
8. Husband of aunt → Uncle
Relations of Maternal side:
1. Mother's father → Maternal grandfather
2. Mother's mother → Maternal grandmother
3. Mother's brother Maternal uncle
4. Mother's sister → Aunt
5. Children of maternal uncle → Cousin
6. Wife of maternal uncle → Maternal aunt
Blood Relation: Sides
There are two main sides to blood relations:
Paternal Blood Relation: This pertains to relationships on the
father’s side, including siblings, uncles, aunts, cousins, and
grandparents (dada, dadi).
Maternal Blood Relation: This involves relationships on the mother’s
side, comprising similar familiar relationships such as siblings, uncles,
aunts, cousins, and grandparents (nana, nani).
Blood Relation: Types
Blood relation reasoning questions assess the ability to analyze
information about family connections and draw logical conclusions.
The various types of questions for Blood Relation Reasoning are as
follows:
Direct Statements: These questions provide clear statements about
relationships between family members. Candidates need to analyze
these statements and answer a question based on the information
provided.
Example: John is the son of Mary. Mary is the sister of David. How is
John related to David?
Coded Relationships: These questions use symbols or codes to
represent family members (A, B, C etc.) and their relationships (+ for
father-son, * for sister-brother etc.). Aspirants need to decipher the
code based on the given statements and solve the question.
Example: A + B means A is the father of B. C * D means C is the sister
of D. Statement 1: P + Q. Statement 2: S * T. Question: How is P
related to T?
Pointing/Introducing: These questions involve a person introducing
or pointing to another family member. you need to understand the
description and analyze the generation and gender differences to
determine the relationship.
Example: Pointing to a photo, a lady says, “This is the daughter of my
husband’s son.” How is the lady related to the person in the photo?
Family Tree: Sometimes, a question might provide a basic family
tree with some relationships filled in. You need to use the given
information to deduce the remaining relationships.
These questions can get more complex by involving multiple
generations, marriages, and in-laws. But by understanding the basic
family structure and practising these different formats, you can
develop strong reasoning skills to tackle any blood relation question
thrown your way.
