Statements: Some bottles are not cans. All
boxes are drawers. No can is a box. Conclusions: I. Some boxes are not bottles. II. Some bottles are boxes. III. Some drawers are boxes. 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
