68. A restaurant's best-selling dish is its signature pizza. To bring this pizza to the customers plate, 20 minutes of normal time is required by each worker for which each worker is rewarded a 10 percent allowance. What would be the standard time for preparing a single signature pizza?
Answer: B
The standard time for preparing a single signature pizza is 22 minutes.
To calculate the standard time for preparing the pizza, we take the normal time of 20 minutes and add a 10 percent allowance, which amounts to 2 additional minutes. Therefore, the total standard time is 20 minutes plus 2 minutes, equaling 22 minutes.
A) 2 minutes
This option is incorrect because it significantly underestimates the time required to prepare the signature pizza. The normal time required is 20 minutes, and this option does not take into account any allowances.
B) 22 minutes
This option is correct as it includes the 10 percent allowance on the normal time of 20 minutes. The calculation shows that the standard time for preparing the pizza, including the allowance, is indeed 22 minutes.
C) 200 minutes
This option is incorrect as it vastly overestimates the preparation time for the pizza. The normal time is only 20 minutes, and there is no scenario provided that would justify such an inflated time requirement.
D) 20 minutes
While this option reflects the normal time required to prepare the pizza, it fails to account for the additional 10 percent allowance that is standard in this context. Therefore, it does not represent the standard time, which should be higher.
Conclusion
The correct answer of 22 minutes accurately incorporates the additional time allowance based on the normal preparation time. All other options fail to reflect either the proper calculations or the required allowances, underscoring the importance of accounting for standard time in operational assessments.
