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.
2.
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.

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.

Why can't all bags be lamps? So is option 'C' correct?

All bags are cakes.
All lamps are cakes.
(Venn Diagram Approach).
Draw a rectangle, name it "cakes"
Lamps and bags will come inside this rectangle, right?
Now draw a circle inside the rectangle and name it "bags"
Now for lamps there are two cases,
i.We can draw a circle "lamps" that overlaps with "bags"
ii. We can draw a circle that is disjoint from "bags"
These are the two options. At a time only one can be true right? (Because two circles can never intersect and be disjoint at the same time).
So the answer is Either.

What exactly do we have to follow? the venn diagram approach or subject predicate distributed undistributed conclusions ?

Can anyone tell me the concept behind this types of problem?

The answer should be D as some lamps are bags and all lamps can also be bags. So here lies the confusion. So the conclusion can be challenged and thus it is D none follows.
