The "N- 1" ordering mode has been popularized all over the country, and catering associations such as Xianning City, Hubei Province and Xinyang City, Henan Province have issued proposals one after another, advocating catering enterprises in their jurisdictions to promote the "N- 1" ordering mode, that is, N- 1 person ordering.
Not long after the introduction of "N- 1", Liaoning introduced the "N-2" ordering mode, that is, 10 guests can only order eight people's dishes, and when the dishes are not enough, they can increase them appropriately to prevent waste.
For example, if 9 people (6 women and 3 men) have dinner, it can be judged that the number of cold dishes is 9*0.5=4.5, and the number of hot dishes is 9* 1.2= 10.8. Because there are more women than men, the number of dishes is generally even, so we can discard the numbers after the decimal point.
That is, this meal has 14 dishes, including 4 cold dishes and 4 hot dishes 10.
Thirdly, the choice of vegetarian dishes in hot dishes. From "234", we can know that:
Boutique/vegetarian dishes are1.8 = 9 * 20%;
Semi-vegetarian is 2.7 = 9 * 30%;
Pure meat is 3.6 = 9 * 40%;
Because there are more ladies in this meal, you can increase vegetarian dishes and semi-vegetarian dishes and reduce pure meat. The final product is 1, vegetarian dishes 2; Semi-vegetarian is 3; Pure meat is 3; Tang 1.
