A.正常廢品數(shù)量=(投入生產(chǎn)數(shù)量-在產(chǎn)品數(shù)量)×正常廢品率
B.正常廢品數(shù)量=(月初在產(chǎn)品數(shù)量+本月投產(chǎn)數(shù)量)×正常廢品率
C.正常廢品數(shù)量=(月初在產(chǎn)品數(shù)量+本月投產(chǎn)數(shù)量-總廢品數(shù)量-月末在產(chǎn)品數(shù)量)×正常廢品率
D.正常廢品數(shù)量=(月初在產(chǎn)品數(shù)量+本月投產(chǎn)數(shù)量-月末在產(chǎn)品數(shù)量)×正常廢品率
E.非正常廢品數(shù)量=總廢品數(shù)量-正常廢品數(shù)量
