SYLLOIGSMS: explanation
Statements

 Some doors are windows
All windows are floors
All floors are ceilings

Conclusions:

Some doors are floors
All windows are ceilings

Explanation:
See here in this subject and predicate will be there

Doors is subject and floors are predicate in conclusion 1.. similarly windows is subject and ceilings is predicate in conclusion 2.
So we need to solve conclusions through venn diagrams..remember we used to draw circles in our childhood the same method.

K listen..lets take statement 1

Some doors are windows so…

According to 2nd statement now we can draw


According to 3rd statement diagram becomes

Now see conclusions
Some doors are floors(see in diagram some doors are floors so it is correct)
All windows are ceilings(see all windows comes under ceilings)


Problem 2
Some doors are windows
All windows are floors
All floors are ceilings

Conclusions:

Some doors are floors
no floors are doors

solution: this is a exclusive case .. see in conclusions.. conclusion 1 is starting with some and conclusion 2 is starting with no..

this is some no  case.. so in some no case if both subject and predicate are equal.. then we can directly keep answer as 3.(either conclusion 1 is true or conclusion 2 is true)

note: in syllogisms .. we can say statement true only if it is definitely true.. if it has doubted statements we cannot decide the statement as true..
I think definitely u might not have understood this

See for example 3 u will get clear idea..

Problem 3
Some doors are windows
All windows are floors
All floors are ceilings
No ceiling is hero
Conclusions:

Some doors are not hero    
Some ceilings can be hero(this is anyway wrong..y because already in statements its given no ceiling is hero)


Here consider conclusion 1.. some doors are not hero..here we can say by diagram that some doors are not hero..so people will think it as true sentence
So that is wrong .. y because in statements he didn’t given relation about doors and hero.. so we canot conclude it as correct statement so it is false.




Problem 4:possibility cases will be there

Problem 2
Some doors are windows
All windows are floors
All floors are ceilings

Conclusions:

Is there possibility that Some doors are not  floors
no floors are doors


When we consider ..possibility cases.. consider conclusion 1: Is there possibility that Some doors are not  floors.. definitely yes.. there is a possibility
Of some doors are not floors.. so it is correct..
