Introduction: Syllogisms

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.

There are four categories you must remember. These tell you how many objects have a certain attribute or how many you have selected.

You can select:
All (i.e. you can select every object in the group.)
Some (i.e. you can select a few objects in the group.)
None (i.e. you can leave out all objects in the group.)
Some Not (i.e. you can leave out a few objects in the group.)

1. ALL
Statement:- All A are B
Every object of Type A is also an object of Type B. You can pick any object in A and it will definitely lie in B.

2. SOME
Statement:- Some A are B
There are a few objects in A that are also in B.

3. NO
Statement:- No A are B.
When we are sure that there is nothing in A that is common with B, we say that no A are B.

4. SAME NOT
Statement:- Some A are not B.
We are sure that there are some objects of Type A that are not of Type B
