Question

    In the question below some statements are given followed by three conclusions 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 the given conclusion definitely follows from the given statements, disregarding commonly known facts.

    Statements: Only a few Computer are Monitor.

    No Monitor is a Scanner. Only a few Scanner is Printer. Conclusions: I. All Printers can never be Monitors. II. All Computers can never be Scanners. III. Some Printers can be Computers.
    A Only Conclusion I follows Correct Answer Incorrect Answer
    B Only Conclusion II follows Correct Answer Incorrect Answer
    C Only Conclusion III follows Correct Answer Incorrect Answer
    D Only Conclusion I and II follow Correct Answer Incorrect Answer
    E All Conclusions I, II, and III follow Correct Answer Incorrect Answer

    Solution

    No Monitor is a Scanner (E) + Only a few Scanner is Printer (I) → Some Printer are not Monitor (O*) → Probable conclusion → All Printer can never be Monitor. Hence conclusion I follows. Only a few Computer are Monitor (I) + No Monitor is a Scanner (E) → Some Computer are not Scanner (O) → Probable conclusion → All Computer can never be Scanner. Hence conclusion II follows. Only a few Computer are Monitor (I) + No Monitor is a Scanner (E) → Some Computer are not Scanner (O) + Only a few Scanner is Printer (I) → Probable conclusion → Some Printer can be Computer (I). Hence conclusion III follows.
