    1) Average = 1.5
    This doesn't give any information about individual prices of books.
    All we know is
    (X + y + z) = 4.5
    There are many combination which satisfy this.


    2) say x = 1.5
    we need median of 1.5 , y ,x
    Not sufficient

    combining 1 and 2
    average is 1.5 and one of the book 1.5
    That means among rest of the 2 books one book cost s more than 1.5 and one cost s less than 1.5
    or
    Both costs 1.5 each

    In both the cases 1.5 is the mean
    So C is the answer
