Is the typical value (as consumed) refer to the product after cooking or before cooking?
Nutrition tables give the value for the product alone, as is, unless explicitly stated otherwise. Cereal sometimes describes a serving as Xg cereal plus Yg milk of a certain fat content, for example. But there should always be the “pure” values for 100g, as most food labeling laws require. 

The product description confirms this by explicitly stating “as sold”: 


  A 1/4 pack (as sold) provides... Calories 110 5.5%, Sugar trace trace, Fat 1.5g 2.1%, Saturates 0.1g 0.5%, Salt trace trace of your guideline daily


If you check the table carefully, you’ll notice that for a 1/4 pack (slightly over 100g) the value for fat is 1.5g. This fits what the eggs in egg noodles would contribute, but is significantly less than what per the cooking instructions should be added for stir-frying.

If you want or need to calculate your calorie intake, weigh the product before your chosen preparation method and use basic maths to calculate the calories or other nutritional values. Any additions (like the aforementioned oil) need to be calculated separately.
