Hai. friends
Actually syllogism has ,the statements could therefore be classified into the following two types
a) universal propositions like"all" or " none"
ex: All lecturers are research scholars.
No student refers to research study material.
b)particular propositions like " some" or "some...not"
eg: Some vehicles are cost prohibited.
Some roads are not good.
And the syllogism statement has two types
Interference and Conversion
In interference.. there is no change in subject and predicate.
for ex:
in contraverse, conversion has interchanged their subject and predicate.
there is some simple formula that is easy to memories
Denote "All as A"
"NO as E"
"Some as I"
"Some ..not as O"
formula,
In interference
A=A
E=I
In Conversion,
A=A
E=E
I=I
Eg:
1.All Students are music lovers-A
NO music lover is cruel- E
(Here "All denotes A
so A=I and E=O)
Answer: (Interference)
Some students are music lovers
Some music lover are not cruel
(here, no change in subject(students) and predicate(music lovers)
(In Conversion)
Some music lover are students
No cruel is music lover
(here there is change in subject and predicate)

Very easy. If one is particular definitely conclusion should be particular (particular means come) without middle term.

HI, everybody
some tips to crack a syllogisms problems.
We follow the certain rules of syllogisms,
one can solve the venn diagrams and other solved by others method.
but shortcut is very simple.
Example:
some dogs are cats.
all cats are horses.
we follow the rules of syllogisms
some+all= some
and we also cancle the cats, because it is common for both the statement.
condition: 1. all dogs are horses.
2. somes dogs are horses. (answer)
3. some horses are not dogs.
we can always see the condition then solve syllogisms problem
firstly we cancle the cats matching with two statement.
and according to rules we can check (some+all= some) for two sentence syllogisms.
and after we analise some dogs are horses to match the condition.
it the answer.
