Syllogism are generally solved by making Venn diagrams, but before discussing diagrams, lets discuss some important terms related to syllogism.

Every syllogism question consists of one statement based on which we have to find the conclusions or possibilities that can be derive from the given statement.

Every statement and conclusions or possibilities contains QUANTIFIERS.

QUANTIFIERS are the words that specify a quantity which can be applicable to all situations or some particular situations.

E.g. - All, No, Some, Few, Every etc.

Note - SOME can be used as ALL

SOME = AT LEAST ONE/ MINIMUM ONE
SOME = ALL

CONCLUSIONS are the derived statements which are definitely true in every situation

POSSIBILITIES are also derived statements but are true in any one or at least in one of the cases or conditions

Now, lets start discussing the concepts with the help of Venn diagrams.

Every statement is described with the basic diagrams and possibilities diagrams to explain the conclusions and possibilities.

STATEMENT 1

ALL A's ARE B's

CONCLUSION - Some B's are A's

POSSIBILITY - All B's are A's

STATEMENT 2

CONCLUSION - No B is A

POSSIBILITY - No possible cases in this case

STATEMENT 3

SOME A's are B's

CONCLUSION - Some B's are A's

POSSIBILITY - 1) All B's are A (SOME = ALL)
2) All B's are A

STATEMENT 4

SOME A's ARE NOT B's

CONCLUSION - NO CONCLUSION as there is no statement which satisfies all the diagrams.

SPECIAL CASES

It includes the cases in which either one or other condition will be true.

1) NO A IS B SOME A's ARE B's

CONCLUSION - Either 1 or 2 follows.

2) ALL A's ARE B'S SOME A's ARE NOT B's

CONCLUSION - Either 1 or 2 follows.
