The winter of last year was extremely cold. Little Swan Garment Factory wanted to make a batch of down jackets. It planned to make 250 sets a day, and the work was completed in two weeks. In order to catch up with the work, it was actually completed 4 days ahead of schedule. How many sets did it actually make per day?
