In a company, the total customer calls on Monday, Wednesday and Friday are 15,500 and the total calls on Tuesday and Thursday are 12,500. The average calls on Saturday and Sunday are 7,000. What are the average calls per day in a week?
- A6500
- B7500
- C7000
- D6000
Solution & Step-by-step Explanation
To find the average calls per day for the entire week, we need to calculate the total number of calls across all 7 days and divide it by 7.
Step 1: Calculate total calls for each group of days
Total calls on Monday, Wednesday, and Friday (3 days) = 15,500
Total calls on Tuesday and Thursday (2 days) = 12,500
Total calls on Saturday and Sunday (2 days) = Average×2=7,000×2=14,000
Step 2: Calculate total calls in the week
Total Calls=15,500+12,500+14,000=42,000
Step 3: Calculate average calls per day
Average Calls Per Day=
7
Total Calls
=
7
42,000
=6,000
Step 1: Calculate total calls for each group of days
Total calls on Monday, Wednesday, and Friday (3 days) = 15,500
Total calls on Tuesday and Thursday (2 days) = 12,500
Total calls on Saturday and Sunday (2 days) = Average×2=7,000×2=14,000
Step 2: Calculate total calls in the week
Total Calls=15,500+12,500+14,000=42,000
Step 3: Calculate average calls per day
Average Calls Per Day=
