Question

You need 76 people to process volume. You have 84 people rostered and an average of 82% attendance. Calculate VET round up.

a) 0
b) 4
c) 8
d) 12

Answer 1

To find needed VET personnel, calculate the expected attendance and subtract from the volume requirement. With 84 people rostered and an 82% attendance rate, 8 additional people are needed for VET.

Step-by-step explanation:

To calculate the number of people needed to be rostered on a Voluntary Extra Time (VET) to process a given volume when there is a known average attendance rate, follow these steps:

• Calculate the expected attendance by multiplying the total number of people rostered by the average attendance percentage.
• Subtract the required number of people to process volume from the expected attendance to find the shortfall.
• If there is a shortfall, calculate the VET needed by rounding up to the nearest whole number, as you cannot have a fraction of a person.

For the question at hand:

• Expected attendance is 84 people rostered × 82% = 68.88, which rounds to 69 people expected.
• The shortfall is 76 people needed - 69 people expected = 7 people.
• Since you can't have a fraction of a person, you round up to the nearest whole number, meaning that 8 additional people are needed for VET.

The correct answer is therefore (c) 8 additional people for VET.
