Verbal Reasoning - Syllogism - Discussion

Hope this will help you:

a-> universal affirmative statement. eg. all men r mortal.
e-> universal negative statement. eg. no men r animal.
i-> particular affirmative statement. eg. some men r wise.
o-> particular negative statement. eg. some men r not animal.
Now how to use in statements. easy way 4 you to remember the words(select only vowels).

Paragraph-> a+a=a.
Agree-> a+e=e.
Editor-> e+i=o.
Reason-> e+a=o.
Britain-> i+a=i.
Video-> i+e=o.

So in above e.g. its. e+a=o. but there is not sch a option and option 3 is correct. therefore only option 3. Hope you got it. If there is error let me know.

Option 1 and 2 are negatives, and it is true, if negative conclusions are true take its negation. If negation is true then negative statements will not follows, otherwise it follows.

Only conclusion (3) follow because,

According to 1 Venn diagram its follow the conclusion. But in 2 Venn diagram it does't. That's why answer is wrong.

Same its with conclusion (2) and conclusion (2) is also wrong.

Answer is 1,2,3 follows then how only 3?

Can anyone explain how only 3rd option? According to me 1, 2, 3 answer!

The statement clearly says that no door is dog but it didn't specify that no cat is door. So here door can be cat or cat can be door. So only 3 follows.

The above first statement is not clear then how can we decide the answer? There may be a chance to be some cats can be doors and can't be, will you please tell me the proper solution for this?

Yes agree to all guys as there is no other possibility except the door but as in all venn diagram problems we leave the possibility scenario here also drop 3 will be correct.

But no. 4 is not valid as the conclusion says all cats are dogs but right conclusion is all dogs are cat.

Conclusion: Some cat is not door, is correct?
