    In each of the questions below some statements are given followed by some Conclusions. You have to take the given statements to be true even, if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

    Statements:  Only a few Facebook are

    Messenger. No Messenger is Hangout. Only a few Snapchat are Whatsapp. No Whatsapp is Facebook. Conclusions: I. Some Messenger are Snapchat. II. No Snapchat is a Messenger.

    C If either conclusion I or II follows. Correct Answer Incorrect Answer
    D If neither conclusion I nor II follows. Correct Answer Incorrect Answer
    E If both conclusions I and II follow. Correct Answer Incorrect Answer

    Solution

    No Whatsapp is Facebook (E) + Some Facebook are Messenger (I) → Some Messenger are not Whatsapp (O*) + Some Whatsapp are Snapchat (I) → Hence neither conclusion I nor II follows but it will make a complementary pair i.e. I-E. Hence either conclusion I or II follows.
