EXPLANATIONS
1.All registers are folders (A) +All folders are columns (A) =A+A=A=All registers are columns (A).Hence I does not follow.
  Again, some registers are files (I)→conversion→Some files are registers(I)+All registers are folders(A)=I+A=I=Some files are olders (I).Hence the possibility in II exists. Hence conclusion II follows.
Answer: (b)
2.All solutions are liquids (a)+No liquid is a mixture (E)=A+E=E=No solution is a mixture (E).Hence conclusion II follows.
  Now, No solution is a mixture (E) +All mixtures are matters (A) =E+A=O* =Some matters are not solutions. Hence the possibility in I exists. Hence conclusion I also follows.
 Answer: (e)
3.All novels are pages (A) →conversion → Some pages are novels(I)+No novel is a book (E)=I+E=Some pages are not books (O).Hence the possibility in II exists. Hence conclusion II follows.
Again, All novels are pages. Hence I follows.
Answer: (e)
4.Some doctors are intelligent (I) +No intelligent is poor (E) =I+E=O=Some doctors are not poor(O).Thus the possibility in I exists. Hence conclusion I follows. But II does not follow because ‘No intelligent is poor’.
Answer: (a)
5.All thins are circulars (A) +No circular is a metal (E)=A+E=E=No thin is a metal(E).Hence, I does not follow.
Again, No paper is thins are circulars (A) =E+A=O*=Some circulars are not papers (O*).Hence, II does not follow.
