Question
Statements: Some mats are bedsheets. All
bedsheets are chairs. Some chairs are desks. Conclusions: I. Some desks are bedsheets. II. Some chairs are mats. III. Some mats are desks. In each question below are given three statements followed by three conclusions numbered I, II and III. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.ÂSolution
A + I = No conclusion. Hence, conclusion I and III will not follow. Some mats are bedsheets (I) + All bedsheets are chairs (A) = Some mats are chairs (I) ⇒ conversion ⇒ Some chairs are mats (I). Hence, conclusion II will follow. Alternate method: 
Conclusion I: Not necessarily true based on given venn diagram. Conclusion II: It is true based on given venn diagram. Conclusion III: Not necessarily true based on given venn diagram.
