  • Question

  • Statements: Some pens are books. All schools are books. Some colleges are schools.

    Conclusions:

    1. Some colleges are pens.
    2. Some pens are schools.
    3. Some colleges are books.


  • Options
  • A. Only I and II follow
  • B. Only II and III follow
  • C. Only I and III follow
  • D. All follow
  • E. None of these

  • Correct Answer
  • None of these 

    Explanation
    Some pens are books. All schools are books.

    Since the middle term 'books' is not distributed even once in the premises, so no definite conclusion follows.

    Some colleges are schools. All schools are books.

    Since one premise is particular, the conclusion must be particular and should not contain the middle term.

    So, it follows that 'Some colleges are books'. Thus, III follows.

    Some pens are books. Some colleges are books.

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

    Hence, only III follows.
