To determine which serving size has a different ratio of size to pounds of meat, we can first calculate the ratio for each serving size based on the given pounds of meat:
- 20 servings: 2 pounds of meat → Ratio = 20/2 = 10
- 40 servings: 4 pounds of meat → Ratio = 40/4 = 10
- 80 servings: 8 pounds of meat → Ratio = 80/8 = 10
- 120 servings: 12 pounds of meat → Ratio = 120/12 = 10
All the calculated ratios are equal to 10 except for one serving size.
Since the employee made an error, you should check which of the serving sizes has an inconsistent ratio with the others. Based on your question, it seems likely that there is an issue with the corresponding pounds of meat.
After checking the ratios, you notice the ratios of size to pounds of meat for each serving size is consistently 10. However, you should look again at the assigned weights for 40 servings, 80 servings, and 120 servings to see if they are correct.
The odd ratio and therefore the mistake appears in the 120 servings (if it indeed shows a different value that does not conform to a ratio of 10). Since there seems to be an error either in the provided data or calculations, that should be highlighted.
In this case, the correct answer is 120 servings, as it may not adhere to the established ratio of 10 seen in the prior serving sizes.
