    In 1st ques , A can be possible na. then why both are wrong , B is the answer i think

          1. Statements: Some A are B. All A are C. Some B are D. No B is E.
            Conclusions:
            I.No A is E
            II. All E are C.

            I. Either of no A is E or some A are E is possible na??

            If possible then we cannot say that I – definitely does not follow

            II. If All E are C, there is no problem, means possibility occurs of All E are C – this also means that II is not definitely false

            See the word definitely – The conclusion should not definitely follow

            In 10th Q:

            Statements: Some A are B. All C are D. No B is D. All D are E.
            Conclusions:
            I. All A are D
            II. Some C are B

            Is All A are D a possibility ?? No it is not, so this definitely does not follow

      1. mam is type ke question ke option choose karne m doubt rahta he …mam quest me pucha he ki choose the one which definitely doesnt follow….ans suppose my both the statemnt are definitely nt following thn which option i will choose , mam bas yahi confusion he ..plss clear it mam

  2. Some A are B. All B are C. No C is D. All D are E.
    Conclusions:
    I. All A are E
    II. Some B are D
    mam isme 2 kese follow karega ??

    1. .-•~¹°” Ambika : ˆ”°¹~•

      B is wrong , it is not even possible that some B are D so it will definitely not follow

      one of which definitely does not follow (or is not a possibility of occurrence).
      pehla possibility me follow hoga dekhna

  3. Aw, this was a really nice post. Finding the time and actual effort to generate a top notch article… but what can I say… I procrastinate a whole lot and don’t seem to get anything done.
