A few days are left for LIC AAO 2019 And SBI PO, Clerk Mains are lined up in the coming months. Syllogism concept is not new to the students and it asked in every exam. It is a topic that is solved in very little time and with 100% accuracy. LIC AAO 2019 Preliminary exam came with the new ways of asking the questions syllogism. The concept of Few, Only a few, and Only are coming in every exam so this topic is important. We are providing some concepts of syllogism.
First, we start with some basic concept of Syllogism-

There are three types in syllogism-

1. Positive– where we are 100% sure.
2. Negative– In this, we are sure that it doesn’t
3. Possibility– In this we are not 100% sure but Possible case may occur. In syllogism, a conclusion which is not 100% sure, it’s possibilities can happen i.e we are doubtful in saying it but the possibility may occur
1. Positive conclusion-

Example1. Statement

All books are pens.
All pens are copy.
Syllogism Concept: Concept on Few, Only a few, Only and Some not. |_3.1
Now Check for the conclusion

Conclusion
All book are copy– is right because all part of book in copy
All pen are copy-is wrong
Some books are pens– if all relation is follow then some relation is also follow
Some pens are books– is right
Some copy are pen– is right
All pens are book– This is doubtful we are only sure for some part of pen not all part of pen.

Here- In positive sentences Negative and possible conclusions are false.

2. Negative conclusion-statement
All books are pen
No pens is copy

No copy is pen– is right.

3. Possible case- In syllogism, conclusion which is not 100% sure, it’s possibilities can happen i.e we are doubtful in saying it but possibility may occurs
Statement-
All apple are mango
Some mango are orange
Conclusion-
It is possible that all mango are apple
It is possible that some orange are not apple- right
