Answer :
Final answer:
To calculate the amount of potato needed for a function serving 50 people with wastage, we can multiply the number of people by the amount per person. Accounting for the 20% wastage on cooking and 10% wastage on preparation, we find that 3600 grams of potato are needed.
Explanation:
To calculate the amount of potato needed, we will start by finding the total number of people the recipe serves, accounting for wastage. The wastage on cooking is 20%, which means only 80% of the original amount is used. The wastage on preparation is 10%, which further reduces the amount used to 90% of the 80%.
Let's calculate:
Number of people: 50
Amount per person: 100 grams
Total amount needed:
Total number of people * Amount per person = 50 * 100 = 5000 grams
Wastage on cooking reduces the amount to 80%: 5000 * 0.8 = 4000 grams
Wastage on preparation reduces the amount to 90%: 4000 * 0.9 = 3600 grams
So, you need to order 3600 grams of potato for the function.
