Blood relations is an essential topic in the logical reasoning section of various competitive examinations. This topic assesses students’ analytical abilities and their ability to tackle the solution of logical issues using diagrams rather than numbers. The charts are pretty significant in this case. The correct diagrams result from the proper analysis. Blood relation is any relationship in the world formed by birth or marriage. A birth relation would be a parent, siblings, and any marriage relation established because of marriage, such as brother-in-law and mother-in-law.

Blood Relation

A blood relation between two people is described as a relationship formed through birth and marriage. Blood Relation questions require the examination of facts demonstrating the blood relationship between family members. In this, a link of connections is supplied in the information format. The candidates are quizzed about the relationship between different members based on that data.

Tips for Defining a Connection Between Two Relatives

  • Step 1: The first and most crucial step is to select the two people concerned. 
  • Step 2: Once you’ve decided on the two people, identify the transitional relationship between them, i.e. the relationship that allows a direct relation to be developed between the two people.
  • Step 3: Finally, establish the relationship between the two people.

Also, try to express the male and female members of the family using different symbols, such as squares and circles. This helps significantly to solve the problem.

Types of Blood Relations

Here are the various types of blood relations:

Pointing

In these kinds of questions, someone points to or presents someone through dialogue or another means, and candidates must determine the link between them. Here is an example of blood relation questions:

“She is the spouse of my mother’s father’s sole grandchild,” A replied, referring to a lady. What is their relationship with A?

If we create a family tree, we see that A’s mother’s father refers to A’s grandfather. A’s grandfather has just one male grandchild because the lady is that person’s wife. As a result, A is the grandchild, and the lady is A’s wife. As a result, the correct response is “Wife.”

Family Tree

In this sort of blood relation problem, information on the relation between different distinct family members will be supplied, and candidates will be required to determine the relationships between any two of them. These questions are sometimes referred to as blood-type questions. Let us consider an example of blood relation questions:

  • M’s kid is R. 
  • N’s father is H. 
  • D is R’s wife. 
  • R and N are brothers. 
  • D’s brother is K. 
  • R’s son’s name is E. 
  • A’s father is K. 
  • What is the connection between K and A?

If we look closely at the question, Kanav is Akash’s father.

Thus, the relationship between Kanav and Akash is between father and son.

Coding-Decoding Blood Relation

In these questions, family members are denoted by specific codes or symbols. Candidates must locate the correct answer by deciphering the symbols. Consider the following example of blood relation questions:

In a particular code, the blood relations are represented through the following symbols:

  • M $ N denotes that M is N’s sister.
  • M % N denotes that M is the brother of N.
  • M & N denotes that M is the mother of N.
  • M @ N denotes that M is the son of N.

Determine the connection between W and S using the following expressions: 

S % T @ U $ V $ W.

From the above statements, we can infer that-

  • S is the brother of T, T is the son of U, U is the sister of V, and V is the sister of W. 
  • Now, we do not know if W is a male or female person in the family. 
  • Thus, we can say that W is the uncle or aunt of S.

Blood Relation Chart

A blood relation chart has all the details about the indirect reference and the direct relation between two family members. It helps to solve the questions quickly by providing clarity to students about the way blood relations are represented. Here is a blood relation chart for reference:

Conclusion

Blood relations are the relations among family members based on birth or marriage. Knowledge of the family’s varied hierarchical structure, which is usually three generations above and three generations below the current generation, is helpful to find the blood relations. Blood relations entail questions to determine a relationship between family members, and applicants must answer the questions depending on the facts provided. The blood relations chart is a helpful resource to understand various blood relations.
