We are providing you step by step information regarding XAT 2018 Logical Reasoning (LR) preparation. What are the various sections & topics according to Exam pattern, which aspect requires extra attention & time? As you are going to appear for XAT entrance, the first thing you required to understand what Logical Reasoning is?
To solve any problem concerned to LR, you have to apply a good mathematical process step by step to draw a unique conclusion from given statements. But keep one thing directly that whatever conclusion you have drawn must satisfy all preordered statements.
Before starting preparation you required to know XAT Syllabus of reasoning & applications. Why did you require to study them? How it would help you in career prospects because you are supposed to become part of management field.
After completing your MBA Degree, when you will be working as a manager or appointer in a corporate. At that time this test will need to taken by you to hire new employees. If you are very well prepared & know all the terms & tactics concerned with logical reasoning then only you will be able to lead & judge others.
Note: If any statement is true, then there are chances of possibilities depending upon the extent of truth in that statement, whether it is clearly true, likely to be true or nearly true. And in case of the false statement, no possibilities can be considered.
According to current test requirements, Logical Reasoning is the common term which is used solely for various types of reasoning.
1. Deductive Reasoning
This test analyzes you on the basis of your ability to deduce genuine facts which is acceptable everywhere.
For e.g. Major Premise: All Human are mortal
Minor Premise: Socrates is human
Conclusion: Socrates is mortal.
Explanation: As given in the below-mentioned Venn diagram that mortality is eternal & earned by every human being. Socrates was human that is why he was mortal too
Note: Always remember that in Deductive logic you are not gathering new information. You just arrange the information which is already given in a new way but acceptable in every situation
2. Inductive reasoning
This is somewhere concerned with mathematical induction which you have studied in previous classes. To prove any statement we just followed a format more than one time, say ‘N’ number of times & then generalize the statement to give a final response.
Note: For conclusions based on the inductive reasoning you may not be 100% sure. You have to conclude on the basis of trend pertaining.
Example.1. ALL swans are white
Explanation: This conclusion is drawn by considering a large number of ‘white swans’ with no emphasis on whether any ‘black’ swan exists or not. But it is not acceptable with 100% surety that there is no ‘black’ swan exists in the world.
Inductive reasoning may be wrong, as in this case when a black swan is established it appears to be wrong. Most of the time responses satisfied the given situation.
Example. 6, 9, 12, 15, ? 2.
Response: The trend has shown that the response is 18.
Explanation: You may not be 100% sure for above response. Because it is not mentioned that to which scale the series belongs, whether temperature, hours or some other scale.
3. Abductive Reasoning
This form is very similar to the second form ‘inductive’ reasoning. It clearly depends on guesswork as its solution requires assumptions based on probability. The condition whose probability is more is considered to be more feasible.
Example: Major Premise: The box is filled with red balls.
Minor Premise: James has a red ball in his hand.
Conclusion: The red ball in James’s hand was taken out of the box.
Explanation: To solve this case we can perform only guesswork. It is just a possibility that the red ball in James’s hand was taken from the box, but it is also possible that the ball is given by someone else to James.
Keep practicing as much as questions as you can. Sometimes your attempting speed depends on logic, which is needed to solve the question at right time in the right way.
Exercise will help you a lot to manage time for a various type of questions. You will be able to identify what type of question required how much time.
Classify your problem on time span & complexity level & devote time according to requirement.
Do not solve the question in a various way anytime you attempting it. Just maintain your own mode & stick to that only otherwise you will be confused.
When you start preparing to make note of those problems which creates the issue when you have been solving them.
