A parcel delivery company delivered 103600 packages last yea

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 two years? (Negative value should be indicated by a minus sign. Round your intermediate calculations and final answer to 2 decimal places.)

Solution

Productivity = Total packages handled /No. of drivers employed

Last year Productivity = 103600/83 = 1248.19 packages per driver

This year Productivity = 112160/93 = 1206.02 packages per driver

Percentage change in productivity = ((This year Productivity - Last year Productivity) / (Last year Productivity))*100

= ((1206.02-1248.19)/(1248.19))*100 = -3.38%
