Question
Statement : No mobiles is a charger. Some
chargers are not phones. No phone is a bell. Conclusion : I. No mobile is a bell. II. Some mobiles are not phones. III. Some chargers are mobiles. In each question below are given three statements followed by three conclusions numbered I, II and III. You have to take the three 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.Solution
No mobiles is a charger(E) + Some chargers are not phones(O) ⇒ No conclusion. Hence Conclusion I and II will not follow. No mobiles is a charger(E) ⇒ Conversion ⇒ Some chargers are not mobiles(O). Hence Conclusion III will not follow.
