      $1,428,000 is the answer I came up with. 
      I divided the $11,900 by 50 to determine how much was earned per day.  $238.
      I multiplied that by 360 to determine how much interest would be earned in one year.  $85,680
      I then divided that answer by .06 (6%) to find the principal amount invested. $1,428,000.

      Reversing the process:  $1,428,000 X 6%  DIVIDED BY 360  X 50

        I'm real sure this is the answer I came up with. Whether it is correct for the question or not, I'm not positive.
