Question
Statements: All bold are cowards. No
bold is a tall. Some tall are short. Conclusions: I. Some cowards are not tall. II. All tall are not bold. III. At least some short are not bold. In each of the questions below are given three statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of given conclusions logically follows from the given statements disregarding commonly known facts.Solution
No bold is a tall(E) ⇒ Conversion ⇒ No tall is a bold(E) + All bold are cowards (A) ⇒ Some cowards are not tall(O*). Hence, conclusion I follows but conclusion II does not follow. No bold is a tall(E) + Some tall are short(I) ⇒ Some short are not bold(O*). Hence, conclusion III follows.
