Syllogism - Easiest Method to Solve Questions Based on Syllogism

Syllogism is a topic which can be confusing for those students who don't know much about it. Today we are providing you an easiest approach to solve questions based on Syllogism.


Statement 1: Some A are B

Seven kind of conclusions can be made. Try below given conclusion if  they fit in this statement

1. All A are B
2. No A are B
3. Some A are not B
4. All Bare A
5. Some B are A
6. No B are A
7. Some B are not A

Is conclusion 1 following?
Could follow.

No A are B
Impossible.

Some A are not B
It won’t follow in all the cases, but it’s possible. 

All B are A
Again, it’s possible.

Some B are A
Yes. Follow. In all cases.

No B are A
Impossible.Nahinahinahi!

Some B are not A
It could be possible. Won’t follow in all the cases, but yes, it also could be possible.




Statement 2: All A are B

Seven kind of conclusions can be made. Try below given conclusion if  they fit in this statement

1. Some A are B
2. No A are B
3. Some A are not B
4. All B are A
5. Some B are A
6. No B are A
7. Some B are not A

Some A are B?
Yes! Of course! All A are B, that means Some A are Definitely B

No A are B
Of course not!

Some A are not B?
Yes yes. Not following

All B are A
Well, can follow, if A encircles B, i.e. All A are B and All B are A

Some B are A
Of course, some B are A

No B are A
Bullshit conclusion. How can no B are A

Some B are not A
Well, look at 4th conclusion. Its possible that All B are A if A also encircles B. In that case, Some B are not A will not follow. So, there’s a possibility that this 7th conclusion will follow. Understood?




Statement 3: No A are B

Now, let’s try all these conclusions if they fit in this statement

1. All A are B
2. Some A are B
3. Some A are not B
4. All Bare A
5. Some B are A
6. No Bare A
7. Some B are not A

Conclusion 1 following?
Of course not!

Some A are B
Haha..


Some A are not B
No A are B, then Some A are also Not B.. Yes, following!

All Bare A
Clearly, not following!

Some B are A
What the hell. Not following!

No Bare A
Now this is class. Yes, follows!

Some B are not A
Of course will follow! No A are B only means, No B are A, which also means, Some B are not A



Statement 4: Some A are not B
Now, let’s try all these conclusions if they fit in this statement

1. All A are B
2. Some A are B
3. No A are B
4. All B are A
5. Some B are A
6. No B are A
7. Some B are not A

Is conclusion 1 following?

Some A are B
It could be possible! Not in all cases, but it could be possible

No A are B
Again, could be possible!

All B are A
Yes, yes. Could be possible!

Some B are A
Not in all cases, but could be possible!

No B are A
Again, it also could be possible!
