Numerical Ability and Calculation Flashcards

A clerk is tasked with ordering office supplies. They need to order 15 boxes of pens at $12.40 each, 25 notebooks at $3.50 each, and 5 printer cartridges at $45.00 each. What is the total cost of the order before sales tax?

Answer: $498.50

To find the total cost, you must calculate the cost for each item and then add them together. Pens: 15 * $12.40 = $186.00. Notebooks: 25 * $3.50 = $87.50. Cartridges: 5 * $45.00 = $225.00. Total Cost: $186.00 + $87.50 + $225.00 = $498.50.

An employee works 37.5 hours per week at a rate of $18.00 per hour. If 18% of their gross pay is deducted for taxes and 4% is deducted for a retirement plan, what is their net pay for one week?

Answer: $526.50

First, calculate the gross pay: 37.5 hours * $18.00/hour = $675.00. Next, calculate the total deduction percentage: 18% + 4% = 22%. Then, find the total deduction amount: $675.00 * 0.22 = $148.50. Finally, subtract the deductions from the gross pay to find the net pay: $675.00 - $148.50 = $526.50.

A department's budget was $12,500 for the quarter. They spent $4,500 on salaries, $2,750 on supplies, and $1,800 on utilities. What percentage of the budget remains?

Answer: 27.6%

First, sum the total expenses: $4,500 + $2,750 + $1,800 = $9,050. Next, find the remaining amount: $12,500 - $9,050 = $3,450. Finally, calculate the percentage of the budget that remains: ($3,450 / $12,500) * 100 = 27.6%.

Which of the following fractions is the largest: 3/4, 4/5, 7/8, 13/16?

Answer: 7/8

To compare the fractions, convert them to decimals. 3/4 = 0.75. 4/5 = 0.80. 7/8 = 0.875. 13/16 = 0.8125. Comparing the decimal values, 0.875 is the largest, which corresponds to the fraction 7/8.

A batch of 500 invoices needs to be processed. Clerk A can process 25 invoices per hour, and Clerk B can process 20 invoices per hour. If they work together, how many hours will it take them to process the entire batch?

Answer: 11.1 hours

When working together, their combined processing rate is the sum of their individual rates: 25 invoices/hour + 20 invoices/hour = 45 invoices/hour. To find the total time required, divide the total number of invoices by their combined rate: 500 invoices / 45 invoices/hour ≈ 11.11 hours.

If a roll of paper is 36 inches wide and a clerk needs to cut strips that are 2 1/4 inches wide, what is the maximum number of full strips that can be cut from the roll?

Answer: 16

First, convert the width of the strips to a decimal or improper fraction. 2 1/4 inches is equal to 2.25 inches. Then, divide the total width of the paper roll by the width of one strip: 36 inches / 2.25 inches = 16. Therefore, 16 full strips can be cut.
