某企业计划生产A.B两种产品，耗用甲材料的单耗分别为10公斤和20公斤，产量分别为1000件和500件，甲材料的计划单价为10元，每次采购费用为1600元，单位材料的年保管费为其价值的40%。

甲材料的经济订货批量计算过程为：

A产品甲材料的耗用量为：10х1000=10000(KG)

B产品甲材料的耗用量为：20х500=10000(KG)

甲产品的年需要量为：10000+10000=20000(KG)

每次订货的固定成本为：1600元

年保管费用=10х40%=4(元)

所以经济订货批量：Q=(2х1600х20000/4)1/2=4000(KG)

如果每次进货量在5000公斤以上，可享受2%的折扣，此时经济批量是多少?
