Problems Related To Relations

Introduction:

Mathematics is a subject learned right from childhood to our graduate degree. It has a wide number of topics covered. All the lessons learned either big or small have their own application in the real world. Problems related to relations is one such that has a huge advantage.

Relation Questions In Reasoning:

Relation questions in reasoning are taught even during the school period. In relation questions in reasoning, the reason is the ability to continuously make things sensible, apply the logic behind them, and justify them.

Relation questions in reasoning can be mainly categorized into two under logical reasoning

• Deductive reasoning
• Inductive reasoning

Deductive reasoning is also known as deductive logic is used in problems having one or more sentences. Inductive reasoning involves steps of observations to end with a general principle.  These are the two main relation questions in the reasoning involved.

Blood Relations Logical Reasoning:

Blood relations logical reasoning is one of the most interesting topics covered under Logical Reasoning. Almost all entrance exams have questions on blood relations logical reasoning. It has such great importance. Blood relations logical reasoning tests the analytical skills of a student. There are three types of questions in blood relations logical reasoning. They are as follows

1. Dialogue/ Conversation Based
2. Based on Puzzles
3. Coding-Decoding

Blood Relations Topics:

• Jumbled descriptions
• Relational puzzle
• Coded relations
• Miscellaneous questions

1. Jumbled Descriptions:

Here the question provides a description in a jumbled manner. It gives info on the relationship between two members of the family. We have to decode the descriptions that are jumbled to find the exact relationshipRelational Puzzle:

Unlike the previous question, this section will have a question that has all the information about the family members in a straightforward and simple manner. More are the number of family members. Most probably this section will have a combination of two or three families

2. Coded Relations:

In some logical reasoning, the members of the family are represented by certain codes. Symbols can also be used to represent relationships. The codes or symbols could be +._ $,*,&,#,@,! etc. The answers to these types of logical reasoning are obtained by decoding the relationships represented by the symbols. The only hard process here is that only by solving all the options given, one can arrive at the final correct answer

3. Miscellaneous questions:

Here the questions involve a combination of blood relations with either direction or seating information. One with knowledge of directions and seating information will be able to easily solve these questions

Example:

Question: On pointing to a photograph of a boy in his room, Mr Ravi said, “That boy is the son of the only son of my mother.” What is the relation of Mr Ravi to that boy?

1. Brother
2. Uncle
3. Cousin
4. Father

Solution: The boy in the photograph pointed, is the only son of the son of Ravi’s mother i.e., the son of Ravi. Hence, Ravi is the father of the boy. Hence Option D. Father is the correct answer.

This example uses decoding the jumbled descriptions.

Relationship Logical Reasoning Questions:

Relationship logical reasoning questions can be used in any environment to learn about the relationship between members. Taking an example of relationship logical reasoning questions, 

Question:

Rakesh is the son of Amir’s father’s sister. Santhosh is the son of Ramya who is the mother of Ganguly and grandmother of Amir. Arun is the father of Anushya. Arun is also the grandfather of Rakesh. Ramya is the wife of Arun.

How is Rakesh related to Ramya?

1. Nephew
2. Son
3. Grandson
4. Data inadequate

Solution:

Since Ramya is the grandmother of Amir and Amir and Rakesh are cousins (from the first statement). Rakesh should be a grandson to Ramya. Therefore the answer is Option 3. Grandson.

In this example, a question is given, to members of a family. Question is to find how Rakesh is related to Ramya. We have to understand the concept given in the question, analyze and then find the solution. This is an example of relationship logical reasoning questions.

Logical Ability Blood Relations: 

In problems on logical ability blood relations, blood relation is an important part of the reasoning section. This logical ability blood relations section is used in many competitive examinations. Based on the logical ability of blood relations information given in the problem one is required to find the particular relation between members of the family.

Conclusion:

Though it is a subject of matter learned by students, problems related to logical ability or logical reasoning is applied in our daily life. It is good if everyone is aware of the concept.
