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.

HAI DEEPTHI.......This is Harmandeep Singh
would u please explain me these term
A-->E (A conversion is E)
E-->E
and as well as in ur 1st example those lines meaning i.e."then conclusion will comes as some actors are dancers or some dancers are actor or some singers are actors or
some dancers are the singers"
eg:1.Some actors are singers.
2.All the singers are dancers
as per the rule E+A=E
first see common in both sentences is singers that singers is cancelled then conclusion will comes as some actors are dancers or some dancers are actor or some singers are actors or
some dancers are the singers
eg:1.All books are trees.
2.All trees are lions.
as per the rule A+A=A ,A-->E
then conlusion is All books are lions or some lions are books or some trees are books or some lions are trees

HAI DEEPTHI.............THIS IS AMRUTHA
CAN U EXPLAIN BELLOW WHICH IS WRITEN BY U
let ALL=A,SOME=E
formula
A+A=A
A+E=NO CONCLUSION
E+E=NO CONCLUSION
E+A=E

There is farmula if some + all = some
statement is 1- Some actors are singers.
2- All the singers are dancers.
Than as per rule some will come and singers is comman for both sentences hence that would be cancelled and conlusion will come as ---- some actors are dancers.
statement is 1- Some actors are singers.

Hello friends I have a short technique,
In here no need to draw diagram. If two statement is given then 1st look the mediator if it contain ALL, NO then close ur eyes and sure that it is distributiv if the mediator have no ALL, No then the conclusion has a -ve term.
Let eg
some actor are dancer
all dancer are singer
ANS; some actor are singer/some singer are actor
some actor are dancer
some dancer are singer
ANS; some singer are not dancer

Does the logical deduction step of conversion and implification is also applied here along with the venn diagram to get the conclusion?
