A parcel delivery company delivered 103,000 packages in 2009, when its average employment was 84 drivers. In 2010 the firm handled 112,000 deliveries with 96 drivers. What was the percentage change in productivity from 2009 to 2010

-4.85%

Explanation:

The computation of the change in productivity is shown below:

                  a                                b              a divided by b

Year            Packages           Drivers        Output

2009          103,000                 84            1226.19

2010           112,000                 96             1,166.67

Now the change in productivity is

= (1,166.67 - 1226.19) ÷ (1226.19)

= -4.85%
