An electronic product processing factory originally planned to produce 2,400 dozen computer chips in 16 days with 5 people. Later, due to the increase in orders, it adopted a new technology for production, and the work efficiency was 1.5 times that of the original one. However, it still took 8 people and 20 days to complete the production task. In this way, the subsequent increase in production is how many times the original planned production.
某电子产品加工厂原计划5人16天生产2400打计算机芯片，后来由于订货增加，采用新工艺生产，工效是原来的1.5倍，但还需要8人20天才能完成生产任务．这样后来生产的增加数是原计划生产数的多少倍．
