Answer :
This ensures that you have enough potato to cover the necessary servings after accounting for the specified wastage percentages during both preparation and cooking.
To calculate the amount of potato needed for the recipe, considering wastage during cooking and preparation, let's break down the process step by step.
Cooking Wastage: 20% of the total cooked amount will be wasted due to cooking.
This means that only 80% of the cooked amount will be usable.
Preparation Wastage: Before cooking, 10% of the required potato amount will be wasted during preparation.
Now, let's calculate the total amount of potato needed:
Total Potato Required without Wastage:
Total Potato = 100 grams/person * 50 persons = 5000 grams
Preparation Wastage:
Preparation Wastage = 10% of 5000 grams = 0.1 * 5000 grams = 500 grams
Total Potato Needed after Preparation Wastage = 5000 grams + 500 grams = 5500 grams
Cooking Wastage:
Cooking Wastage = 20% of 5500 grams = 0.2 * 5500 grams = 1100 grams
Total Potato Needed after Cooking Wastage = 5500 grams - 1100 grams = 4400 grams
So, you would need to order 4400 grams (or 4.4 kilograms) of potato to account for both the cooking and preparation wastage for the recipe to serve 50 people, with each person requiring 100 grams of potato puree.
