In the school cafeteria, they prepare 490 servings of 50 g of boiled meat for one lunch. Meat loses 30% of its weight by cooking. How many kilograms of raw meat must the school canteen prepare for this lunch to cook?

Correct answer:

m =  35 kg

Step-by-step explanation:


m·(1-30/100) = 490 · 0.050

70m = 2450


m = 2450/70 = 35

m = 35
