Question
Statements: Some trucks are buses. All buses
are cars. All cars are bikes. Conclusions: I. Some trucks are bikes. II. Some cars are buses. III. Some trucks are cars. 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
Some trucks are buses (I) + All buses are cars ⇒ Some trucks are cars(I) + All cars are bikes ⇒ Some trucks are bikes (I). Hence, conclusion I and III follows. All buses are cars (A) ⇒ Conversion ⇒ Some cars are buses(I).Hence, conclusion II follows.
