Answers with Explanation:

1. All audis are toyotas (A) +All toyotas are volvos (A) =A+A=A=All audis are volvos (A).Hence I does not follow.

Again, some audis are hyundais (I)→conversion→Some hyundais are audis(I)+All audis are toyotas(A)=I+A=I=Some hyundais are olders (I).Hence the possibility in II exists. Hence conclusion II follows.

Answer: (b)

2. All bluebells are buttercups (a)+No buttercup is a clover (E)=A+E=E=No bluebell is a clover (E).Hence conclusion II follows.

Now, No bluebell is a clover (E) +All clovers are daisys (A) =E+A=O* =Some daisys are not bluebells. Hence the possibility in I exists. Hence conclusion I also follows.

Answer: (e)

3. All CPUs are mouses (A) →conversion → Some mouses are CPUs(I)+No CPU is a book (E)=I+E=Some mouses are not books (O).Hence the possibility in II exists. Hence conclusion II follows.

Again, All CPUs are mouses. 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 things 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.

Answer: (d)
