Question
Statement : Some buckets are mugs.
> Some mugs are tubs. All tubs are plastics. No plastics is a white. Conclusion : Some plastics are buckets. Some whites may be tubs. Some whites are mugs. Some plastics may not be tubs. In each of the questions below are given three statements followed by three conclusions numbered I, II and III and IV. 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
I + I =No conclusion. Hence, conclusion I will not follow. All tubs are plastics (A) + No plastic is a white (E) ⇒ No tub is a white (E) ⇒ Conversion ⇒ Some whites are not tubs (O) ⇒ Probable conclusion ⇒ Some whites may be tubs (I). Hence, conclusion II follows. Some mugs are tubs (I) + All tubs are plastics (A) ⇒ Some mugs are plastic (I) + No plastic is a white (E) ⇒ Some mugs are not whites (O).Hence, conclusion III will follow. All tubs are plastics (A) ⇒ Conversion ⇒ Some plastics are tubes (I) ⇒ Probable conclusion ⇒ Some plastics may not be tubs (O). Hence, conclusion IV follow.
