Syllogism is one of the most important and interesting topics in Reasoning and Solving Syllogism is always fun if you understand the shortcuts. If you understand the below concepts I assure you that you can solve 5 syllogism problems in just 2 min.

Syllogisms often appears as a part of Logical Reasoning or Verbal Reasoning. It consists of some premises (statements) and one or more conclusions. The conclusions are derived from the given statements. The statements and conclusions may often seem to be illogical or go against what we know to be facts according to our daily lives. But we MUST assume the statements to be true. Whether the conclusion is true or not in the context of the true statements given, is what the question is about in syllogisms.

Have a Pen with you. Go through all the concepts one by one. Understand how to draw Venn Diagrams for each concepts. Then understand how the conclusion are made for each concepts.(Just don’t Scroll down fast!!!).

Then work out the problems.

I insist you again. GO ONE BY ONE. Understand it. Then go to the next one. Make sure you are thorough enough with the given concepts.

You don’t need to memorize any statements or any conclusions. All you need is to UNDERSTAND.

Believe Me. It’s very simple. It is not ROCKET SCIENCE.

With the introduction of new pattern questions on syllogism in Bank exams it has become important to use short method to solve such lengthy syllogism questions. Most of the students use Venn Diagram method to solve syllogism. No doubt the method is easy to use, but it is time taking to solve the new Reverse Syllogism questions by Venn Diagram, in which you have to check each option to satisfy the condition given in the question. So switching to RULES for SOLVING SYLLOGISM is best way to solve such question in short time.

The first step is to make a Venn diagram. Second step is deriving the conclusion. Let’s go to all possible concepts. (Concepts = Statements)

CONCEPT 1 Some A is B.

The Diagram for Some A is B is

A and BThe possible conclusions are,

1) Some A is B

2) Some B is A


 CONCEPT – 2 – Some A is B and Some B is C

The Diagram is,

A and B and C

Now the Possible Conclusions are,

Between A and B                                                             Between B and C

Some A is B                                                                      Some B is C

Some B is A                                                                       Some C is B

There is no DIRECT CONNECTION between A and C. So it is not possible to derive any conclusion between A and C.


CONCEPT 3 – All A is B

The Diagram is,All A is B

The Conclusions are,

All A is B.

Some A is B.

Some B is A.


IMPORTANT NOTE : WHEN THE STATEMENTS ARE POSITIVE, THE CONCLUSIONS MUST BE POSITIVE.

CONCEPT 4 – All A is B and All B is C

ABC

The Conclusions are,

Between A and B             Between B and C                          Between A and C                        

All A is B.                         All B is C.                                    All A is C.

Some A is B.                    Some B is C.                               Some A is C.

Some B is A.                    Some C is B.                               Some C is A.


 Concept 5 – Some A is B. All B is C.

JJThe possible conclusions are,

Between A and B                Between B and C                  Between A and C

Some A is B                       All B is C                               Some A is C

Some B is A                       Some B is C                           Some C is A

————————————–Some C is B


 Concept 6 – All A is B and Some B is C

nn

The possible conclusions are,

Between A and B                          Between B and C

All A is B                                       Some B is C

Some A is B                                  Some C is B

Some B is A

There is no DIRECT CONNECTION between A and C. So it is not possible to derive any conclusion between A and C.


 

Concept 7 – All B is A and All C is Akk

The Possible Conclusions are,

Between A and B                                 Between A and C

All B is A                                              All C is A

Some B is A                                         Some C is A

Some A is B                                         Some A is C

There is no DIRECT CONNECTION between B and C. So it is not possible to derive any conclusion between B and C.


Concept 8 – No A is Bmm

The Possible Conclusions are,

No A is B

No B is A

Some A is not B

Some B is not A


 

When NO comes in Statement, Some-not should follow in Conclusion

 Concept 9 – All A is B and No B is C

mm

The Possible Conclusions are,

Between A and B                  Between B and C                  Between A and C

All A is B                               No B is C                               No A is C

Some A is B                          No C is B                               Some A is Not C

Some B is A                          Some B is not C

—————————————-Some C is not B


Concept 10 – All A is B and No A is C

mm

The Possible Conclusions are,

Between A and B                Between A and C                 Between B and C

All A is B                             No A is C                              Some B is not C

Some A is B                        No C is A

Some B is A                        Some A is not C

————————————–Some C is not A


 Concept 11 – Some A is B; No B is C

mmThe Possible Conclusions are,

Between A and B                  Between B and C                 Between A and C

Some A is B                          No B is C                               Some A is not C

Some B is A                          No C is B

—————————————-Some B is not C

—————————————–Some C is not B


 Concept 12 – Some A is B; No A is C

mm

The Possible Conclusions are,

Between A and B                Between A and C                Between B and C

Some A is B                         No A is C                            Some B is not C

Some B is A                         No C is A

——————————————-Some A is not C

——————————————-Some C is not A


Note: In all the above, the conclusions are made based on the statements. There in only one case where the conclusions are determined based on the conclusion itself. It is called as Merging Concept.


 MERGING CONCEPT

This concept is applicable when more than one conclusion does not follows.

Rules:

The two non-following conclusions must be of same character.

One conclusion must be positive (All/Some)

One conclusion must be negative (No/Some-not)

Let me explain this concept with some examples.


Example 1:

Stmt : All Lotus are Flowers; No Lilly is Lotus.

Conclusion: No Lilly is a flower; Some Lilly is Flowers.

The first step is to draw Venn Diagram. mm

Now Check the conclusions.

No Lilly is a flower. (It’s not true)

Some Lilly is flowers (It is also not true)

Two conclusions are false. And Both are same Characters (Lilly and Flower). One is Positive and one is negative. It satisfies all the rules of Merging Concept.

So the Answer is Either (i) or (ii) Follows.


Example 2

Stmt : Some Cameras are Radios; Some Statues are Cameras.

Conclusion : Some Radios are statues; No Radio is a Statue.

mm

Conclusion 1 : Some Statues are Radios (It is false) (No direct relation between Statue and Radio)

Conclusion 2: No Radio is a Statue (It is False) (It is a negative conclusion) (When statements are positive, conclusions must be positive).

Now Check for merging concept.

Two Conclusions are False.

They are of same character. One is Positive and other is Negative.

Answer is Either (I) or (II) Follows


POSSIBILITY

Whenever the term “Possibility” OR “Can” comes in Conclusion, We need to check this simple table.

mm

Let me explain you guys with an example.

Statements:

Some Mangoes are Apples; Some Bananas are Apples; Some Branches are Bananas

Conclusions:

Some Mangoes are Bananas

Some Branches Being Apples is a Possibility

Some Branches are Mangoes

All Apples Being Mangoes is a Possibility

The First Step is to draw Diagram.

mm

Conclusion 1: It is False. (No Direct Connection between them).

Conclusion 2: No relation between Branches and Apples. “Possibility” is there. (Chk Table) (It is True)

Conclusion 3: It is False (No Direct relation)

Conclusion 4: Between Apples and Mangoes “Some” can come. “Possibility is there” (Check Table). It is also true.

So the conclusion is II and IV Follows.

Important Rules:

  • Draw Venn Diagrams(Basic Diagram & Possibility Diagram) according to the Statement.
  • If the conclusion does not satisfy the Basic Diagram then there is no need to check the possibility diagrams.
  • If the conclusion satisfies the Basic Diagram then it must satisfy all possibility diagrams.
  • The first Venn diagram in all images shown below are Basic Diagrams & remaining are Possibility Diagrams.

All A are B:

Some A are B:

Some A are not B:

Example:

Statements:
All Circles are Squares
Some  Squares are Roses

Conclusion 1: Possibility Diagram
csr-poss

Conclusion 2: Possibility Diagram
csr-poss-two

Conclusions:
I. All Roses being Square is a possibility
II. Can all Circles be Roses
Both (I) and (II) follow

I will start with explaining basic syllogism terminology which will be followed by practical examples.

syllogism basics

Some

some case syllogism

NO

no case syllogism

Case #   All – Some

Let!
           You have 1000 $ in your pocket.One of your friend needs 600 $ to pay his Bill.He wants to borrow money from you.He comes to you and say,”Do you have 600 $ ?.What would you say,”Afcoss Yes!”.Even if He ask for 1 $, or 999 $ .Your answer will always “Yes!”.
So Overall you had 1000 $ which is called “All ” or All of the money you had & What is your friend want some of the money like here 600 or it could be 1$ or 999 $ and what we call that some portion of money out of it.or ” Some”.
That’s why In ” All ” Case, “Some” is always true.

Example:

Statement : All A are B.
Possible Diagram
Conclusion
All A are B             ✓
Some A are B         ✓
Some B are A         ✓
Some A are not B   ✘
Some B are not A   ✘
syllogism shortcuts
sets
Now Here we can see that A contains set of numbers. So we call it is as Set A and Same for B ‘Set B’.
All the numbers in A is contained by B hence All A is B true But All the numbers in B is not in A or not contain by A so All B is A → False.
Now Let understand How All A is B → True But All B is A → False
Let  Box A & Box B . Here We can see that Box B is inside the Box A Hence Box B can fit into Box A but Box A cannot fit into Box B.
some cases syllogism

Case #    Some – Some Not

syllogism tricks
Assume you have given the exam & you passed with some marks that mean you got some marks and some or not. Even if you passed the exam with 99% marks still you missed the 1%. So Even 99% is count under the same case.and 1% is also counted in some case.hence In ‘Some’ case ‘Some Not’ is true.
Statement : Some A are B

Conclusion
All B are A        ✘
Some B are A    ✓
No A is B          ✘

Statement : Some A are not B
Possible Diagram
syllogism
Explanation

Here we see that Set A & Set B has some common values hence we can say that Some A is B & Some B is A But there also some values which are not common in both A & B.So We can also say that Some A are not B & Some B are not A.

Case #    No- Some Not

no some not syllogism trick
Assume You have no money in your pocket.So if you got no money.It means also that some money is not in your pocket.Having No means also some not.

syllogism shortcut tricks

Statement Some A are B, Some B are C

syllogism shortcut
Conclusion
syllogism
 
Explanation (Simple case A,B & C) :
 Let A, B & C are three person. A & B know each other. B & C know each other But B knows both.Now, Will A talk about C? Answer is ‘Not!,Neither Positive Nor Negative’ because he doesn’t know him.So conclusion C is False.
Possibility Case (Conclusion : D,E & F) :
Now Let’s take a look at conclusion E.Now Suppose there is raining outside your home and someone comes to you and say there is a possibility to rain today.What would you say to him,’Mad!”The Same scenario is here By looking at diagram it clearly says that Some B are A then how could say it is ‘possible’ which is actually there.Hence Possibility makes it wrong or false the conclusion.So Conclusion E is wrong.
Now talk about conclusion F which says Some A are not c which we don’t know but it says to let it is a ‘possibility’ so anything could be possible which doesn’t make our statement wrong or contradict with statement.If we make it like this below:
syllogism
We talk here about possibility which could be anything which especially not contradict with our statement.So F which was False in Simple Case but When we talk about the possibility is becoming true.
Let another example for this.Now Let There is a cloudy sky outside your home.Someone comes to you and say ,” There is a possibility that there might be rain today”, Now you have no idea whether it rain today or not.So you might be say ,” Bro! It is possible”.Now here you cannot talk about negative because in Syllogism Negative Answer will never be there.

Tricks to Solve Reverse Syllogism

Syllogism is a game played with circles logically. Usually statements will be given and we have to find the appropriate conclusion which follows the statements. In Reverse Syllogism, as the name suggest, Conclusions will be given and we have to find the appropriate statements which satisfies the conclusions.
It may seems like a lengthy process, But if you are strong in basic concepts of syllogism along with some elimination tricks, you can master this topic.
Let us brush up some basic concepts of syllogism with some examples.

Example.1

Statement: All A are B 

Possible Conclusions:

1. Some A are B
2. Some B are A
3. Some B are not A

Example. 2

Statement: Some B is C 


Possible Conclusions:

1. Some C is B
2. Some B is not C
3. Some C is not B
4. All B are C is Possible/ All B may be C
5. All C are B is Possible

Note: Some B are C is Possible cannot be a conclusion
May be/ Can be means Possibility
At least some means Some
Very few means Some

Example. 3

Statement: No C is D 


Possible Conclusions:

1. No D is C
2. Some C are not D
3. Some D are not C
4. All C can never be D
5. All D can never be C
Now let us combine all the statements of the above three examples. 

Example. 4

Statement: 

All A are B
Some B is C
No C is D

Possible Conclusions:

1. No D is C
2. Some C are not D
3. Some D are not C
4. Some A are not D
5. Some B are not D
6. All A are C is Possible
7. No A is D is Possible
8. No B is D is Possible
9. Some A are D is Possible
10. Some B are D is Possible
11. All B can never be D
12. Some A are D (or) No A is D
13. Some B are D (or) No B is D

Now Let us discuss the elimination tricks to solve Reverse Syllogism with some examples:

Example.1

Conclusions: 

I. All A can never be B
II. Any A which is a D is also CStatements: 
A. Some A is B. All B is C. Some C is D
B. Some A are D. All A are C. No B is D
C. No A is C. All C are B. Some C is D
D. All A are C. Some C are D. No D is B
E. None of theseAnswer: Option B 


Explanation:

  • First let us take a quick scan on the statements
  • Take Option A and compare it with conclusion I,  All A can never be BSome A is B. All B is C. Some C is D (Option A is eliminated)
  • Take Option C and compare it with conclusion II  Any A which is a D is also C No A is C. All C are B. Some C is D (Option C is eliminated)
  • Now we have Option B and D
  • Take Option B and compare with both the conclusions.

Some A are D. All A are C. No B is D 

  • From the Shaded region it is clear that All A can never be B and Any A which is D is also C. (Both conclusions Follows, so Option B is the answer)
  • In Exam You can stop once you find the answer.
  • But, Now let us take Option D also and check.

All A are C. Some C are D. No D is B 

  • Here All A can never be B may or may not be true
  • Therefore, option D doesn’t follow.

Example. 2

Conclusions: 

I. Atleast Some A may be C.

II. All C being B is a Possibility.

Statements: 

A. Some A are B. Some B are C. All C are D. No A is D.
B. All A are B. No C is B. Some A is D
C. No C is A .All A are D. Some D is B
D. All A Are B. Some A are D. No D is C
E. None of theseAnswer: Option D 

Explanation:

  • First let us take a quick scan on the statements
  • Take Option B and compare it with conclusion II,  All C being B is a Possibility.  All A are B. No C is B. Some A is D (Option B is Eliminated)
  • Take Option C and Compare it with Conclusion I Atleast Some A may be C. No C is A. All A are D. Some D is B (Option C is eliminated)
  • Now we have Option A and D
  • Take Option A and Compare with both the conclusions

Some A are B. Some B are C. All C are D. No A is D. 

  • Here conclusion I don’t follow
  • Now Let us take Option D and Compare with both the conclusions

All A Are B. Some A are D .No D is C 

  • Both the Conclusions Follow. To understand the concept more easily, above diagram can be redrawn as.

Preferable method to solve Reverse Syllogisms is Elimination method. In this method, we try to eliminate the options step by a step which cannot be answer. Steps should be taken in eliminating the options are given below.
First, always identify “Universal Negative” conclusion, then eliminate those options which do not have a single universal negative statement.
Secondly, check “Particular Negative” conclusion, then eliminate those options which violates this condition.
Thirdly, check “Universal Positive” conclusion, then eliminate the option which also violate this condition.
In last, check “Particular positive” conclusion, then eliminate the option which also violate this condition.
In last the remaining option will be your answer.
Let’s discuss it with examples.
Example 1
Conclusion:
(1) No toxic is injection. (2) Some injections are glucose.
Statements: 
(A) All toxic are tablet. No tablet is glucose. Some glucose are medicine. All medicine are injection.
(B) Some toxic are tablet. All tablet are injection. Some injection are glucose. All glucose are medicine.
(C) All tablet are toxic. No injection is toxic. Some glucose are injection. All glucose are medicine.
(D) Some injection are toxic. All injection are tablet. Some toxic are glucose. All glucose are medicine.
(E) Some medicine are toxic. Some toxic are injection. Some injection are tablet. All tablet are glucose.
Solution:
In Reverse Syllogism, Conc.1is Universal negative or disjointed set. So first we will try to find out the option which has the statement following this conclusion.
We can see that, In option B, D and E, there is no negative statement. So these cannot be answer.
In option A and C, there is negative statement. In option C, you can see the statement 2 and statement 3 depict the given conclusion.So, C is the answer.
You can also check option A, but when you have got your answer, there is no use of wasting time.
Now, Question is why I checked first option C?
I checked both option A and C, but in C I found related information to Conclusion, So, I go in detail of it.
Example 2
Conclusion:
(1) No toxic is injection. (2) Some injection are not glucose.
Statements:
(a) All toxic are syrup. Some syrup are glucose. Some glucose are medicine. All medicine are injection.
(b) Some toxic are syrup. All syrup are injection. Some injection are glucose. All glucose are medicine.
(c) All syrup are toxic. Some toxic are not injection. Some glucose are injection. All glucose are medicine.
(d) Some injection are not toxic. Some injection are not syrup. Some toxic are glucose. All glucose are medicine.
(e) No medicine is syrup. All toxic are medicine. All injection are syrup. No syrup is glucose.
Solution:
In this also conclusions are “No toxic is injection” and “Some injection are not glucose”.
First we will identify the option which has statements depicting “No toxic is injection”.
Except option E, all options do not have any “Universal negative” statement. So our answer will be E.
If you have gone through meritshine video and previous article, you basics have been clear, no need to check of the option E. Still for your convenience let’s check Option E.

We can see that All toxics are medicine, All injections are syrup and no medicine is syrup. So, no toxic is injection.
All injections are syrup and No syrup is glucose. So, no injection is glucose which infers that some injection is not glucose.
Example 3
Conclusion:
(1) All toxic are injection.              (2) Some glucose are not medicine.
Statements:
(A) All toxic are syrup. Some syrup are glucose. Some glucose are injection. All medicine are injection.
(B) All toxic are syrup. All syrup are glucose. Some toxic are not medicine. All glucose are injection.
(C) All syrup are toxic. Some toxic are injection. Some glucose are injection. All glucose are medicine.
(D) Some injection are not toxic. No injection are syrup. No toxic are glucose. All glucose are medicine.
(E) No toxic is syrup. All syrup are glucose. All toxic are medicine. All toxic are injection
Solution:In this there is no universal negative statement. Now, we will first focus on Particular Negative statement.
In option A and option C, there is no negative statement, so these options are eliminated.
In option D, last statement is “All glucose are medicine” given, so it will not be the answer.
Now let’s check option E and B.
In option E, last statement has already depicted the first conclusion, but there is no restriction on Glucose and medicine. So, this will also not be our answer.

We have already eliminated four options. So the remaining will be our answer i.e. B.
Now let’s check option B. But, in exams you don’t need to check when you have elimated four options.

We know “some toxic are not medicine” means atleast one element of toxic is not medicine.
In diagram B.1, all toxic are glucose so, so at least one  element of glucose will not be medicine.
Example 4
Conclusion:
(1) Some car are bus.    (2) No bus is plane.    (3) All plane are train
Statement:
(A) Some car are not plane. All drum are train. Some bus are not plane. All planes are drums.
(B) Some bus are car. All bus are train. No plane is bus. All car are train.
(C) Some bus are car. Some car are plane. Some train are plane. No plane is bus.
(D) All bus are train. All plane are drum. Some bus are car. All drum are bus.
(E) All drum are train. No train is car. All bus are car. All plane are drum.
Solution:
In given conclusions, Conc.2 is universal negative type. So, we will first identify options which have this type of statement.
Option B, C and E are this type of statement, so options A and D are eliminated.
In option B and C, statement “No plane is bus” available. Let’s first see these both option.
In option B, there is no relation between plane and train. This option is also eliminated.
In option C, If we check Conc.3 “All plane are train” which is universal affirmative for it statements should be also universal affirmative. So, this option is also eliminated.
So, answer is E. Let’s check it also.
