The processing of a batch of parts can be completed by the apprentice alone in 12 days. Now, the processing task of this batch of parts is assigned to the master and the apprentice at a ratio of 2:3. As a result, the apprentice only worked for 5 days due to illness, so the master did 132 more tasks than assigned. How many parts are in this batch?
