    Input:    85   16  36  04  19   97   63   09
    Step I: 97   85   16   36   04   19   63   09
    Step II: 97   85   63   16   36   04   19   09
    Step III; 97   85   63   36   16   04   19   09
    Step IV: 97   85   63   36   19   16   04   09
    Step V; 97   85   63   36   19   16   09   04
     
    Study the above arrangement carefully and then answer the following questions:
    Which one of the following would be the last step for the input below?
    Input: 03 31 43 22 11 09

    A) Step II                          

    B) Step III         

    C) Step IV             

    D) Step V

    Correct Answer: D

    Solution :

    Direction: In the given arrangement, the numbers have been arranged in descending order (from left to right) in a sequence.
    Input :     03 31 43 22 11 09
    Step I :      43 03 31 2 11 09
    Step II :    43 31 03 22 11 09
    Step III :   43 31 22 03 11 09
    Step IV  :  43 31 22 11 03 09
    Step V: 43 31 22 11 09 03
    Clearly, Step V is the last step for the given input.
