    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. Statements: All fruits are leaves. Some mangoes are rotten. All rotten are fruits. Conclusions: I. Some leaves are rotten. II. Some mangoes are fruits. III. All leaves are either rotten or mangoes.
    A Only conclusions I and II follow Correct Answer Incorrect Answer
    B All the conclusions follow Correct Answer Incorrect Answer
    C Only conclusion II follows Correct Answer Incorrect Answer
    D Only conclusions II and III follow Correct Answer Incorrect Answer

    Solution

    All rotten are fruits (A) + All fruits are leaves (A) → All rotten are leaves (A) → Conversion → Some leaves are rotten (I). Hence conclusion I follows but conclusion III does not follow. Some mangoes are rotten (I) + All rotten are fruits (A) → Some mangoes are fruits (I). Hence conclusion II follows.
