# RBI Grade B Reasoning | Critical Reasoning Concepts | Mixed Type Questions

The RBI Grade B recruitment notification for the year 2018 was released recently. This much-awaited exam is just about 40 days away and we are positive that, at this stage, your preparations must be in full swing. In our last few posts about the RBI Grade B exam, we have shared:

In this article, let’s dive a little deeper and look at one of the most discussed topics of RBI Grade B preparation, i.e. Critical Reasoning. Here, we will be looking at the following:

• Importance of Critical Reasoning In RBI Grade B Exam
• Critical Reasoning: Basic Definitions & Concepts
• How To Solve Mixed Type or Combination Sets In RBI Grade B Critical Reasoning | Solved Examples [Concept VIDEO]

RBI Grade B Reasoning | Importance of Critical Reasoning

Critical reasoning is one of the most important question types for the reasoning section of the RBI Grade B exam. In fact, in the last year’s RBI Grade B phase-I exam, 10 out of the 60 questions asked in reasoning fell under the topic of critical reasoning. The following table shows the number of critical reasoning questions asked in the RBI Grade B phase-I exam over the last three years.

 RBI Grade B Exam Year Critical Reasoning Questions Total Reasoning Questions 2015 8 60 2016 13 60 2017 10 60 *Please note these are approximate numbers. May vary across slots

Based on the above the table, it is evident that critical reasoning forms an important part of the reasoning section. Now that we have established how important the topic is, let us move on to some basic concepts and finally the concept video.

RBI Grade B Reasoning | Basic Definitions & Concepts

The key to solving critical reasoning questions lies in a good understanding of the definitions of terms like assumptions, inferences, threats, cause, and effect etc. So make sure you revise these before you watch the video. Following are the important definitions.

• Logic is a system of reasoning that allows us to arrive at conclusions using available data and critically check the validity of these conclusions.
• Argument / Stimulus: An argument is set of two or more propositions (called premises) in such a way that all but one of them (premises) provide support for the remaining one (conclusion).
• The line of reasoning: The transition or moment from premises to the conclusion, the logical connection between them, is called the line of reasoning.
• Assumption: the unstated premises that make or break the conclusion of the argument/ stimulus
• Conclusion: Contains the central idea of the argument. This is what all arguments and assumptions are trying to prove. In short, Conclusion = Premises + Assumption (the one that links the premises)
• Inference: are un-stated partial conclusions that can be drawn from the given premise. They do not contain the central idea, but they lead to/support the central idea. An inference can serve as a link in the line of reasoning but is not the same as a conclusion. A conclusion invariably addresses the central idea of the stimulus whereas inference serves only to support the conclusion. There can be many inferences; such as immediate inference, followed by final inference before it leads to the conclusion.

While individual question types such as statements, assumptions, inferences etc are asked frequently in the exam, most people face problems while solving critical reasoning questions of mixed type. These questions usually have a long passage followed by a set of questions, each asking a different thing.

Here we bring you a critical reasoning video in which you can solve mixed type questions along with the expert and understand the approach.

Hope this helps. All The Best!
