Question

    In the question below some statements are given

    followed by four conclusions I, II, III and IV. 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 statements and then decide which of the given conclusion definitely follows from the given statements, disregarding the commonly known facts. Statements: Few Lamp is Post. All Post is Lighter. No Post is Cook. All Cook is Top. Conclusions: I. Few Lighter is not Cook. II. No Post is Top. III. Few Top is Lighter. IV. Few Lamp is Lighter.
    A Only conclusion I follows Correct Answer Incorrect Answer
    B Only conclusions I and IV follow Correct Answer Incorrect Answer
    C Only conclusions I, II and IV follow Correct Answer Incorrect Answer
    D Only conclusion IV follows Correct Answer Incorrect Answer

    Solution

    No Post is Cook (E) → Conversion → No Cook is Post (E) + All Post is Lighter (A) → Some Lighter are not Cook (O*). Hence conclusion I follows. No Post is Cook (E) + All Cook is Top (A) → Some Top are not Post (O*). Hence conclusion II does not follow. Some Lighter are not Cook (O*) + All Cook is Top (A) → No conclusion. Hence conclusion III does not follow. Some Lamp is Post (I) + All Post is Lighter (A) → Some Lamp are Lighter (I). Hence conclusion IV follows.
