Blood Relation

A person who is related to another by birth rather than by marriage.Blood relations of a group of persons are given in jumbled form. In these tests, the success of a candidate depends upon knowledge of the Blood Relations, some of which are summarized below. The questions which are asked in this section depend upon Relation.

Questions on Blood Relationship are related to our day to day life. We are bound by our kit hand kin through a chain of relationships. The examiner defines the simple relationships by using rather complicated set of definitions and expects from us to comprehend these definitions rather quickly.
In order to solve these problems, analyse the given statements carefully and systematically.
For examples :
(i) My father's only child means I (Myself).
(ii) Ritu's husband's father-in-law's only daughter means - Ritu (Herself).

Pay particular attention to the information given in the question itself without your personal biases and preconceived notions and assumptions coming to the fore. Questions on Blood Relationship can be solved by any of the following methods:
(i) Deduction Method and
(ii) Pictorial Method
While attempting questions on Blood Relationship, first read all the pieces of information as quickly as possible and then point out the two persons between whom relationship is to be established. Finally, try to co-relate the given relationships. While concluding relationship between two persons be careful about the sexes of the persons involved. Majority of the students tend to define or derive relationship without caring for sex of the persons. Is it possible to define relationship between two persons without knowing their sex?
 Consider the following illustration: A is the child of P and Q.
From this statement can we conclude that P is the father of A. No, it is not possible. Without knowing the sex of either P or Q, it is not possible to conclude that P is the father of A. What we can conclude from the above statement is that'P and Q are parents of A. Thus, we see that the knowledge about the sex of persons is necessary to conclude relationship between the two persons.
Some Important Tips:
(i) First of all choose the two persons, between whom relationship is to be established.
(ii) Next, pin-point the intermediate relationship i.e., such relationship through which long drawn   relationship can be established between the required persons.
(iii) Finally, conclude the relationship directly between the two persons as per the requirement of the question.
(iv) From a particular name we cannot ascertain the sex (gender) of that person. The name does not always show the gender beyond reasonable doubt.
For example, we often hear the same name for male and female in the Punjabi community.The names, Harvinder, Sukhwinder, Gurinder etc. are used for both the sexes in the Punjabi community.
There are certain other names which are used for both the sexes all over the country. For example, Suman, Kamal etc.

The list given below is quite helpful in recognising some indirect relationships and to remember easily the relations may be divided into two sides as given below:
I. Relations of Paternal side:
1.Father's father→ Grandfather
2.Father's mother→ Grandmother
3.Father's brother→ Uncle
