Answer:
30 percent
Explanation:
For clarification,The question says that a company prints 300 calendars in an hour,but ends up printing 90 calendars in one hour,what is then the percentage if the calendars printed?
Let's try and understand this question in a better way with another example of our own.
Assuming we are in bakery and we prepare 100 snacks with 90 minutes everyday since the day we started the job,and on a fateful day,we were only able to prepare only 50 snacks(just half of the total we are normally accustomed to),what will be the percentage of snack we prepared?
Back to the initial question
300 calendars is the norm for this company but they eventually ended up only printing out 90 calendars,the percentage of their work done will be:
90/300 × 100 = 30%
