A parcel delivery company delivered 103,600 packages last year, when its average employment was 83 drivers. This year, the firm handled 112,160 deliveries with 93 drivers. What was the percentage change in productivity over the past years?

-3.38%

Explanation:

The percentage change in productivity over the past years will be calculated thus:

The Productivity will be the total packages handled divided by the number of drivers employed.

Last year Productivity will be:

= 103600/83

= 1248.19 packages per driver

This year Productivity will be:

= 112160/93

= 1206.02 packages per driver

Therefore, the percentage change in productivity = (This year Productivity - Last year Productivity) / (Last year Productivity) ×100

= [(1206.02-1248.19) / (1248.19)] × 100

= -42.17/1248.19 × 100

= -3.38%
