Important Syllogism Questions for IBPS Clerk 2025, Download Free PDF

Syllogism for IBPS Clerk 2025: Syllogism i a high-weightage topic of the Reasoning Ability section. To solve Syllogism questions effectively, it is essential to understand the fundamental rules and logical relationships between the given statements. In this article, we are providing the detailed concept of Syllogism along with the systematic solution strategies, solved examples (with step-by-step reasoning), and a large practice set of important questions.

What is Syllogism

Syllogism is an important topic in the reasoning ability section of IBPS RRB PO and Clerk exams. It tests your logical reasoning and ability to conclude from given statements. Typically, 4 to 5 questions on this topic are included in both the preliminary and mains exams for the IBPS RRB Clerk and PO positions.

Types of Syllogism

In Competitive Examination, Syllogism is a very important topic as this topic can help you to fetch 2 – 3 marks in both the preliminary and mains examinations. To cover this topic, first go through the basic concepts of syllogism and then solve the advanced questions of syllogism. To master the topic, you should practice more and more questions related to different types of syllogisms.

Types of Syllogism:

1. Basic Syllogism: In this type of syllogism questions, the statements are 100% true and the conclusion must be 100% true.

Example:

Statement: All Ball is Oval. Some Oval is Circle.

Conclusion: Some Ball is Circle.

The above conclusion is definitely false as we cannot derive any relationship between Ball and Circle from the above statement.

2. Complimentary pairs (Either – Or Case): In this type of syllogism questions, the statements are 100% true and two conclusions together can be partially true. Here are three cases when ‘Either-Or’ follows:

a. Some + Some not

b. Some + No

c. All + Some not

Example:

Statement: All Ball is Oval. Some Oval is Circle.

Conclusion: 

1. Some Ball is Circle – False (As, there is no relation between Ball and Circle)

2. No Ball is Circle – False (As, there is no relation between Ball and Circle)

But if we consider both the conclusions together, then either conclusion 1 or conclusion 2 is true as this is a complementary pair. If we consider the first conclusion to be true, the second conclusion is false and if we consider the second conclusion to be true, then the first conclusion is definitely false. So, both the conclusions together can be partially true.

3. Only – Only a few: This type of syllogism is a conditional-based syllogism. This is one of the most important concepts to be covered in syllogism, as the questions based on ‘only – only a few’ is confusing. If a statement says ‘only a few A is B’, then only a certain part of A is ,B and the remaining part is not B, and if a statement says ‘Only A is B’, then All B is A, such that B can be only part of A.

4. Possibility-based Syllogism: In this type of syllogism, the conclusion is based on possibilities e.g., if ‘All A is B’ and ‘No A is C’, then ‘Some C being B is a possibility’ is definitely true. In such type of syllogism, ‘can be’ or ‘possibility’ keywords are used.

5. Coded Syllogism: This type of syllogism usually comes in the Mains examination, in which a comparison between two elements is usually defined by code, i.e., symbol, number, etc.

For example: In A&B, ‘&’ represents ‘some’, so we can interpret ‘Some A is B’.

6. Reverse Syllogism: This type of syllogism also comes in Mains examination. In this, few conclusions will be given, and you have to find out which statements given in the options will let follow all these conclusions.

Basic Rules for Solving Syllogism Questions in the IBPS Clerk Exam

To solve Syllogism questions effectively, it is important to understand the basic rules and logical relationships between the given statements. The easiest and most reliable way to do this is by using Venn diagrams. Below are the basic rules you need to remember:

• All + All = All:
  If the statements are “All A are B” and “All B are C,” you can directly conclude “All A are C.”
  
• All + No = No:
  If the statements are “All A are B” and “No B are C,” the conclusion will be “No A are C.”
  
• All + Some = No Conclusion:
  If you have “All A are B” and “Some B are C,” you cannot establish any definite relationship between A and C.
  
• Some + All = Some:
  If the statements are “Some A are B” and “All B are C,” the conclusion will be “Some A are C.”
  
• Some + No = Some Not:
  If you have “Some A are B” and “No B are C,” you can conclude “Some A are not C.”
  
• Some + Some = No Conclusion:
  If the statements are “Some A are B” and “Some B are C,” no definite relationship can be drawn between A and C.

Complementary Pairs in Syllogism

1. Either–Or Case:
   Out of the two given conclusions, exactly one must be true and the other must be false.
   Example:
   • Statement:
     1. Some A are B
     2. Some C are B
   • Conclusion:
     1. Some A are C
     2. Some A are not C
2. Neither–Nor Case:
   Neither of the given conclusions is true, not be derived from the given statement.

Example:

• Statement:
  1. All A are B
  2. Some B are C
• Conclusion:
  1. All A are C
  2. No A are C
