Answer:
25% of the Order was missing.
Step-by-step explanation:
The bookstore ordered a total of 80 Books of Marketing. Out of 80, they got 60 Books. So a total of 20 books were less.
When taking it in percentage, if we divide the no of books received by the total no of books, we would get the percentage of books received. So here is the calculation:
Total Number of Books Ordered: 80
Total Number of Books Received: 60
Percentage of Books Received: (60/80) * 100 = 25%
