In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
(A) If only conclusion I follows
(B) If only conclusion II follows
(C) If either I or II follows
(D) If neither I nor II follows and
(E) If both I and II follow.
Statements: All bags are cakes. All lamps are cakes.
Some lamps are bags.
No lamp is bag.
Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow
Since the middle term 'cakes' is not distributed even once in the premises, no definite conclusion follows. However, I and II involve only the extreme terms and form a complementary pair. So, either I or II follows.
How can we tell that they involve only in the extreme terms and form a complementary pair.

Both the terms are universal affirmative then conclusion also in universal affirmative?

Fellas why using technicals words just can body put it in simple way to understand this problem.

When no conclusion can be drawn then why can't be the answer be option (D) If neither I nor II follows ?

It is possible that lamps and bags from different groups within the group of cakes or it is possible that some bags and lamps are common?

Answer is D i think..as common term is not distributed in statement..
(Tue, Jul 19, 2011 02:38:04 PM)
Ya. No conclusion follows. Since the middle term is not at all distributed.

Let us assume that bag=X, cake=Y & lamp=Z, then from d question it is clearly indicated that X=Y & Z=Y, that means some X=Z which is written in conclusion 1.
But it's contrast statement "NO LAMP IS BAG" is written conclusion 2. so i think the option 1 is the right ans. can any one tell
whether i'm right or wrong ?

Whats exactly a complementary pair?
Please answer me.

This question has multiple choices if we go by venn diagram approach. So we must go by selecting the middle term approach which give us unique answer with no conclusion can be drawn as mid term is not distributed.

Let us assume that bag=X, cake=Y & lamp=Z, then from d question it is clearly indicated that X=Y & Z=Y, that means either some X=Z
or it may be no terms of z match with the x terms.So c is correct option.

According to the rule book to the Deduction.
Rule: Atleast one middle term in the premise should be distributed to give conclusion. If both are undistributed then no conclkusion.
In the given question both are undistributed hence no conclusion.

Please any can explain clearly?
(Tue, Jan 22, 2013 11:30:56 AM)
Only the 1st conclusion follows. The two statements are universal affirmative, so in this case the answer should be either universal affirmative or particular affirmative, there can't be a negative statement as conclusion.

How to find extreme terms in logical reasoning?

What is extreme term and how to find it?
(Fri, Sep 13, 2013 07:51:45 PM)
All (Universal affirmative statement) bags (+) are cakes (-).
All (Universal affirmative statement) lamps (+) are cakes (-).
Here the middle term is cakes (both are minus). At least one plus (+) should contain to follow the conclusion). So here both are minus. Answer is no conclusion.
(Thu, Sep 26, 2013 01:46:39 PM)
Since middle term is not distributed no conclusions can be drawn.
(Fri, Oct 25, 2013 05:02:28 PM)
So. If the task were to find SP conclusion - then there should be no conclusion since M was undistributed in both premises.
However, if we draw some circles - we will see that either I or II follows. (that is why we cannot make SP conclusion. But can solve this task).

Please explain extreme terms?
(Wed, Nov 6, 2013 01:08:08 PM)
If the middle term is not distributed then how could we drawn any conclusion i.e. the answer must be no conclusion and as far as the given options is concerned the answer must be neither I nor II rather than the either I or II.
Please reply what is the correct answer I'm quiet confused.

Guys do these all kinds of logical deductions by drawing vernier diagrams, then you will not get confusion.
