Answer:
97%
Explanation:
Total number of packages delivered = 3,100,000packages
Imperfect orders are as follows;
Deliveries damaged = 45,000
Packages sent to wrong address = 28000
Late deliveries =20,000
Total packages not perfectly delivered = 45000+28000+20000
= 93,000packages
Percent of orders that are not perfectly delivered = Total packages not perfectly delivered/Total packages × 100%
Percent of orders that are not perfectly delivered = 93000/3,100,000 × 100
= 0.03× 100
= 3%
Percent perfect order = 100% - Percent of orders that are not perfectly delivered
Percent perfect order = 100%-3%
Percent perfect order = 97%
