Question

In each of the following questions, two statements are given followed by two/four conclusions I, II, III and IV. You have to consider the two statements to be even if they seem to be true commonly known facts. You have to decide which of the given conclusions if any, follow from the given statements

Statements
Some stones are gold.
Some gold are banks.

Conclusions
I. Some banks are stones.
II. Some gold are stones.
III. No stone is a bank.
IV. Some banks are gold.

• A. Only conclusions II and III follow
• B. Either conclusions III or I follows
• C. Only conclusions I and IV follow
  
  
• D. Only either conclusion Ill or IV and I follow
• E. None of these

Answer 1

The correct option is B Either conclusions III or I follows

Both the premises are particular affirmative (1-type). No conclusion follows from the two particular premises.
Conclusion II is the converse of the first statement.
Conclusion IV is the converse of the second statement.
Conclusions I and Ill form a complementary pair.
Therefore, either I or III follows.
