and B work together to process a batch of parts, which takes 20 days to complete. A first processes alone for 14 days and then performs a new task. B takes over and processes alone for 10 days. At this time, a total of (3/5) of this batch of parts has been processed ), if the rest of the parts are still processed by B alone, how many days will it take?
