In the following question, three statements are given followed by four conclusions numbered I, II, III and IV. You have to take the given statements to be true even if they seem at variance with commonly known facts and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

Statements: Some pictures are frames. Some frames are idols. All idols are curtains.

Conclusions: I. Some curtains are pictures. II. Some curtains are frames. III. Some idols are frames

Answer:

Explanation:

III is the converse of the second premise and so it holds.

Some pictures are frames. Some frames are idols.

 Since both the premises are particular, no definite conclusion follows.

Some frames are idols. All idols are curtains.

Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, it follows that 'Some frames are curtains'. III is the converse of this conclusion and so it holds.

Some pictures are frames. Some frames are curtains.

Since both the premises are particular, no definite conclusion can be drawn.
