    Question

    Read the given statements and conclusions carefully.

    Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statement: All Locker are Key. All Key are Window. Some Locker are Door. Conclusions: I. Some Key are Door. II. Some Window are not Lockers. III. All Window are Door.
    A Only conclusion I follows Correct Answer Incorrect Answer
    B Only conclusion I and II follows Correct Answer Incorrect Answer
    C Only conclusion II and III follows Correct Answer Incorrect Answer
    D Only conclusion I and III follows Correct Answer Incorrect Answer

    Solution

    Some Locker are Door (I) → Conversion → Some Door are Locker (I) + All Locker are Key (A) → Some Door are Key (I) → Conversion →  Some Key are Door (I). Hence conclusion I follows. All Locker are Key (A) + All Key are Window (A) → All Locker are Window (A). Hence conclusion II does not follow. All Locker are Window (A) → Conversion → Some Window are Locker (I) + Some Locker are Door (I) → No conclusion. Hence conclusion III does not follow.
