Quizplus · Accepted Answer

To calculate productivity, we need to divide the amount of output by the amount of input (hours of work). Therefore, in 2004, productivity was 300,000/total hours worked, and in 2005, productivity was 360,000/total hours worked. Since we know that total hours worked was the same in each year, we can compare the productivity directly. 
Productivity in 2005 was (360,000/total hours worked) / (300,000/total hours worked) = 1.2 times the productivity in 2004. That means productivity rose by 20%. Therefore, the answer is C.
