What type of egg will yield 11 and one-half average-size omelettes?

This question is a bit of a trick! You can't determine the type of egg needed based solely on the number of omelettes. Here's why:

* Egg Size Varies: Egg sizes differ, even within the same "type" of egg (e.g., large, medium, small).

* Omelette Size Varies: The size of an omelette depends on the amount of ingredients used, the cook's preference, and the size of the pan.

To answer this question more accurately, you need more information:

1. Average Omelette Size: How many eggs are typically used per omelette?

2. Egg Size: Are you using large, medium, small, or extra-large eggs?

Example:

* Average Omelette: 2 eggs

* Egg Size: Large

* Omelettes Needed: 11.5

In this scenario, you would need 23 large eggs (11.5 omelettes x 2 eggs per omelette).
