Discussion Forum : Logical Deduction - Section 1 (Q.No. 36)
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 tubes are handles. All cups are handles.
Conclusions:
- All cups are tubes.
- Some handles are not cups.
Answer: Option
Explanation:
Both the premises are A type propositions. So, in either, the middle term 'handles' forming the predicate is not distributed. Since the middle term is not distributed even once in the premises, no definite conclusion follows

I think the answer is D. There are 2 primary approaches. If all cups are tubes (option one being correct), then option 2 can be correct or incorrect i.e. depending on whether there are other things which can be handles or not, since it doesn't specify saying, "Cups and tubes make up all the handles present".
The second conclusion (option 2) cannot be drawn if all cups are handles and there are no other handles in the world. Thus, if option 1 is true then option 2 can be happen or not based on what the term "handles" encapsulates.
If option 1 is false, then option 2 is definitely true. So since there is uncertainty on the outcome of option 2 depending on the outcome of option 1 and what the word "handles" means, it cannot be said that the second option would follow in all situations with the statements provided. So the conclusion is neither would follow for certain.

@Tarun.
How can you drive a conclusion that if all cups are handles than all handles are cups? i.e. an overlapping circles using venn diagram.

I think the answer is B.
Because if "some handles are cups" is possible then "some handles are not cup" is also possible.

There are handles which are not cups so some handles are not cups.
Following this shouldn't the answer be B?

@Anirban. I feel the same. Some handles are cups while some are not cups.
So the answer is option B.
So the answer is option B.

I think the answer should be "B" because "Handles" is the outer set of which cups is a subset.

Its not necessary that all handles are cup. Therefore, answer may be "B".

Even I feel the answer is an option B using the venn diagram.
