In a math competition with 1000 students, the students are numbered as follows: 0001, 0002, 0003, ..., 1000. A sample of size 50 is to be drawn using systematic sampling, which divides the 1000 students into 50 groups. If the first group is numbered 0001, 0002, 0003, ..., 0020, and the randomly selected number from the first group is 0015, what is the 40th number that will be drawn?
