a. The productivity of the line is 220 valves per hour.
b. The labor productivity will be increased by 25%.
a. The productivity of the line is
= Number of valves produced ÷ number of hours × increased percentage
= 1,600 valves ÷ 8 hours × 1.10
= 220 valves per hour
b. The labor productivity will be increased by
= Increase in production ÷ Number of valves produced
= 2,000 ÷ 1600
= 1.25
So, the labor productivity will be increased by 25%.
