                BLOOD RELATIONS of a group of persons is given in jumbled form. In the exams, the success of a candidate in the questions on blood relationships depends upon his/her knowledge about the blood relationships. The candidate should be able to work out a relationship between two people from the information given in the question. If the data is tabulated, it can help you in working out the relationship.
               The easiest and non-confusing way to solve these types of problems would be to draw a tree diagram and increase the levels in the hierarchy according to the relation: Grandfather & grandmother will come in the first stage; mother, father, uncle and aunt will come in the second stage; sister, brother and cousin will come at the third stage; niece and nephew will come in the fourth stage and finally, granddaughters and grandsons will come. The above stages are made from the point of view of an individual.
               We have to go through the series of relationships and finally determine the relationship between the two people in the question. The relationship can just be given as a simple statement or as a statement made by a person
First of all choose the two persons between whom the relation is to be established

Next pinpoint the intermediate relationship through which long relationships can be established between the requires persons

Finally conclude the relationship directly between the two persons as required in the question

To develop a blood relation tree, some standard symbols are used to indicate the relationships among the family members. It is not compulsory to follow them; You can design your own symbols to draw the family tree quickly and accurately.

To draw a family tree, first of all identify the males and the females and then try to put each member at the appropriate position in the tree.

P is male = P,   P is female = P
P and Q are married to each other P  Q
P and Q are sibling = P ↔ Q
      P and Q are R’s children = R

Approach to draw the family relations diagram

1) Identify the persons who are in the given information.

2) Identify who are male and who are female.

3) Determine the generations of family.

4) Identify the positions and generation of the family members and draw the diagram with
   relationships among family members using notations.

5) Once the diagram is filled you can Solution the given question.


If the question is "How is A related to B". Then you must know the gender of A to answer the question. Without knowing A's gender, you cannot determine the relation from A to B

If a person is Uncle or Aunt to "A", A is that person's nephew (if A is Male) or niece (if A is female)
Cousin is a common Gender (I mean, you can use this word for both Male and Female)

Ex : A says to B, "you are the son of my grandfather’s only son".
How is B related to A?
How is A related to B?

Ans :      B is Brother of A.
My grandfather’s only son = A's father (grandfather's only son means only ONE  son.. No other son and no daughter also)
                 A is either brother or sister to B
A and B are siblings. B is brother to A as we know the Gender of B. But we don’t              know the Gender of A. So we can’t say whether A is Brother or Sister to B.

Generations : 

-2 Generation : Grand father and Grand Mother (Maternal & Paternal)
-1 Generation : Mother, Father, Brother, Sister, Brother-in-Law, Sister-in-Law, Cousin
+1 Generation : Son, Daughter, Son-in-Law, Daughter-in-Law, Nephew, Niece
+2 Generation : Grand Sons and Grand Daughters
