The correct answer is: A. 0% and 100%
Merrick’s multiple piece rate system is a type of incentive wage system that pays workers a piece rate for each unit of output produced, with the piece rate increasing as output increases. Under this system, ordinary piece rate is given to workers whose level of performance is between 0% and 100% of the standard output.
Option B is incorrect because it includes 120% of the standard output. Under Merrick’s multiple piece rate system, workers who produce more than 100% of the standard output are paid a premium piece rate.
Option C is incorrect because it includes 83% of the standard output. Under Merrick’s multiple piece rate system, workers who produce less than 83% of the standard output are paid a sub-standard piece rate.
Option D is incorrect because it does not include any specific percentage of the standard output.
