In the following question below are given some
statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: All Tables are Chairs. Some Tables are Desks. Conclusions: I. Some Desks are not Chairs. II. Some Chairs are Desks. III. All Chairs are Tables.Solution
Some Tables are Desks (I) → Conversion → Some Desks are Tables (I) + All Tables are Chairs (A) → Some Desks are Chairs (I) → Conversion → Some Chairs are Desks (I). Hence conclusion I does not follow but conclusion II follows. All Tables are Chairs (A) → Conversion → Some Chairs are Tables (I). Hence conclusion III does not follow.
