Question 1

A clerk is asked to find the average number of customer inquiries handled per day over the past week. The daily counts were: Monday (112), Tuesday (98), Wednesday (105), Thursday (115), and Friday (100). What was the average number of inquiries per day?

Accepted Answer

106

Answer

To find the average, first sum the total number of inquiries: 112 + 98 + 105 + 115 + 100 = 530. Then, divide this total by the number of days (5). 530 / 5 = 106.

Question 2

An office supply cabinet is meant to be stocked with staples and paper clips in a ratio of 2:5. If the current inventory shows 48 boxes of staples, how many boxes of paper clips are needed to maintain the correct ratio?

Accepted Answer

120

Answer

The ratio is 2 boxes of staples for every 5 boxes of paper clips. Set up a proportion: 2/5 = 48/x. To solve for x (the number of paper clip boxes), you can see that 2 was multiplied by 24 to get 48. Therefore, you must also multiply 5 by 24. 5 * 24 = 120.

Question 3

A department is purchasing new software licenses that cost $120 each. The vendor offers a 12% discount if 20 or more licenses are purchased. If the department buys 25 licenses, what is the total cost after the discount is applied?

Accepted Answer

$2,640

Answer

First, calculate the total cost before the discount: 25 licenses * $120/license = $3,000. Next, calculate the discount amount: $3,000 * 0.12 = $360. Finally, subtract the discount from the total cost: $3,000 - $360 = $2,640.

Question 4

A clerk is reviewing a timesheet to calculate total project hours. The employee logged 3 hours and 30 minutes on Monday, 2 hours and 45 minutes on Tuesday, and 4 hours and 15 minutes on Wednesday. What is the total time spent on the project over these three days?

Accepted Answer

10 hours, 30 minutes

Answer

First, add the whole hours: 3 + 2 + 4 = 9 hours. Next, add the minutes: 30 + 45 + 15 = 90 minutes. Since 60 minutes equals 1 hour, convert the 90 minutes to 1 hour and 30 minutes. Finally, add this to the hour total: 9 hours + 1 hour and 30 minutes = 10 hours and 30 minutes.

Question 5

A clerk needs to ship a box containing 8 identical manuals. If each manual weighs 14 ounces and the empty box weighs 12 ounces, what is the total shipping weight of the package in pounds and ounces? (Note: 1 pound = 16 ounces)

Accepted Answer

7 lbs, 12 oz

Answer

First, find the total weight of the manuals: 8 manuals * 14 oz/manual = 112 oz. Add the weight of the box: 112 oz + 12 oz = 124 oz. To convert this to pounds and ounces, divide by 16. 124 / 16 = 7 with a remainder of 12. This equals 7 pounds, 12 ounces.
