(b) Percentage change in workforce
= $\frac{12338-17213}{17213}$ × 100
= - $\frac{4875}{17213}$ × 100% = -28.3%
Percentage change in productivity over the period 2011-2014
= $\frac{113-832}{832}$ × 100
= $\frac{29.8}{83.2}$ × 100% = 35.8%
From above solution, percentage change in production = -3%
So, the highest per cent change in the productivity over the period 2011-2014.
