Apprentices A and B are discussing who should cooperate with their master to process a batch of parts. A says, "If I cooperate with the master, I will complete 20% of all the work." B says, "That's not a big deal. If I cooperate with the master, I will complete 40% of all the work." At this moment, the master arrives and tells B, "If A joins to help us, you can process 60 fewer parts." If what they said is correct, how many parts are in this batch?
