A and B cooperate to process a batch of parts, which can be completed in 8 days. In the middle, A stopped work for 3 days due to an accident, so the two of them spent 10 hours to complete the work. How many days will it take if A processes this batch of parts alone?
甲乙两人合作加工一批零件，8天可以完成．中途甲因事停工3天，因此，两人共用了10才完成．如果由甲单独加工这批零件，需要多少天才能完成？
