Question
Three statements are given, followed by three
conclusions numbered I, II, and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: All phones are tablets. No tablet is a calculator. All drives are calculators.       Conclusions: I. Some drives are phones. II. Some calculators are phones. III. No tablet is a drive.Solution
All phones are tablets (A) + No tablet is a calculator (E) → No phone is a calculator (E) + Some calculators are drives (I) → Some drives are not phones (O*). Hence neither conclusion I nor II follow. All drives are calculators (A) + No calculator is a tablet (E) → No drive is a tablet (E) → Conversion → No tablet is a drive (E). Hence conclusion III follow.
