A certain tailor shop employs 10 workers who can normally complete an industrial order in 112 days; however, the shop is prone to power outages, and each outage results in the loss of a full day of work. After 61 days working on a particular industrial order, the shop had had 5 power outages. At the beginning of the 62nd day of work, in order to make up for the outages, the management hired 4 new workers who work at the same pace as the other employees. In the end, the order took 105 days to complete. How many power outages did the tailor shop have after it brought on the new workers?
