All pen are pencil (A) + All pencil are mobile(A) = All pen are mobile(A) ⇒ Conversion ⇒ Some mobile are pen(I). Hence, conclusion I will not follow. All pen are pencil(A) + All pencil are mobile(A) = All pen are mobile(A) + All mobile are laptop(A) = All pen are laptop (A) ⇒ Conversion ⇒ Some laptop are pen(I) ⇒ Probable conclusion ⇒ All laptop may be pen(A). Hence, conclusion II will follow.
