The ratio of the number of parts produced by a factory in January to February is 4:5. Later, the production technology was improved, and the ratio of the number of parts produced in March to the total output of the previous month was 4:3, and 1610 more parts were produced in March than in February. May I ask: How many parts did this factory produce in the first quarter?
某厂一月份与二月份生产零件的个数比为4：5．后来改进生产技术，三月份生产的零件个数与前丽个月的总产量之比为4：3，且三月份比二月份多生产了1610个零件．请问：这家工厂第一季度共生产多少个零件？
