A tech support team resolves 45 tickets in 9 hours. If 3 members leave and workload stays same, each remaining member has to work 25% longer. How many were there originally?
Correct answer: C. 12
- A. 6
- B. 9
- C. 12
- D. 15
Explanation
The total task is resolving 45 tickets in 9 hours, which means the team resolves 5 tickets per hour. Initially, with 12 members, each member resolves 3.75 tickets in 9 hours. When 3 members leave, there are 9 members left. These 9 need to resolve the same 45 tickets, resulting in each member resolving 5 tickets in 9 hours. This is a 33.33% increase in workload per member. Consequently, the original team size that aligns with a 25% increase in workload per member when 3 members leave must be 12, which is the correct answer. Other options do not align with the given workload distribution and percentage increase.
