Discussion Forum : Logical Deduction - Section 1 (Q.No. 2)
Directions to Solve
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.
Give answer:
- (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.
Conclusions:
- Some lamps are bags.
- No lamp is bag.
Answer: Option
Explanation:
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.

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.

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.

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.
or it may be no terms of z match with the x terms.So c is correct option.

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 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 ?

Ya. No conclusion follows. Since the middle term is not at all distributed.
