Question
Statements : All aeroplanes are helicopters.
Some helicopters are kites. All jets are kites. Conclusions : I. Some kites not being helicopters is a possibility. II. Some jets are helicopters. III. Some kites are aeroplanes. 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 helicopters are kites(I) ⇒ Probable conclusion ⇒ Some kites may not be helicopters (I). Hence, conclusion I follows. All jets are kites(A) + Some kites are helicopters (I) ⇒ No conclusion. Hence, conclusion II does not follow. All aeroplanes are helicopters (A) + Some helicopters are kites (I) ⇒ No conclusion. Hence, conclusion III does not follow.
