    Question

    Three statements are followed by three conclusions numbered I, II and III. You have to consider these statements to be true, even if they seem to be at variance with commonly known facts. Decide which of the given conclusions logically follow(s) from the given statement.
    Statements:
    I. Some woods are charcoals
    II.  Some petrol is diesel
    III. All diesel are fossils
    Conclusions:
    (I) Some petrol are charcoals
    (II) Some fossils are petrol
    (III) Some woods are diesel

    A.

    None of the conclusions follow

    B.

    Only conclusion II follows

    C.

    Only conclusion I and III follows

    D.

    Only conclusion I follows

    Correct option is B

    Statements:
    I. Some woods are charcoals
    II.  Some petrol is diesel
    III. All diesel are fossils
    The least possible Venn diagram is:

    (I) Some petrol are charcoals (False because its just a possibility.)
    (II) Some fossils are petrol (True because Some petrol is diesel and All diesel are fossils)
    (III) Some woods are diesel (False because its just a possibility.)
    so, Only conclusion II follows​
    Thus, correct option is (b).
