    Answer : Option C

    Explanation :


    When the process is not up to infinite, use this formula:
    N ((2^t)-1 / 2^t), where the N is the digit, and t is the number of times the digit is repeated.
    i.e., the number is 13, so we have: 13 ((2^7)-1 / 2^7) =13(127/128)
    Hence, the required value is 13(127/128)
