What is the adjusted standard time difference found between Work Factor and MTM for an assembly operation if allowances total 15%?

To determine the adjusted standard time difference between Work Factor and MTM (Methods-Time Measurement) for an assembly operation, we first need to understand how allowances impact these two methods.

In general, Work Factor is a time measurement technique that allows for the calculation of the basic time needed to perform a task, while MTM quantifies the time required for each motion involved in the operation. Both methods factor in allowances, which are buffer times added to account for personal needs, fatigue, and delays.

Given that allowances total 15%, this percentage should be applied to the standard time calculated from both Work Factor and MTM to adjust the times for realistic work conditions. The difference in adjusted times reflects how each method accounts for these allowances.

When applying the 15% allowance, the adjusted standard time would increase based on the calculated basic times from both methods. The time difference that results is a function of the respective basic times and how the allowances apply to them.

Therefore, if the problem specifies a calculated difference and you're determining the exact number, a detailed calculation with the specifics of each method’s output would be required. However, among the provided options, the one that corresponds with the calculated difference when considering the 15% allowance is determined to be
