Ingredients 20623

To prepare poultry risotto for 4 diners, we need 200 g of rice, 150 g of mushrooms, 150 g of peas, 300 g of chicken, 600 ml of stock, and 5 g of salt. What amount of ingredients do we need for 10 diners?

Correct answer:

r =  500 g
h =  375 g
h₂ =  375 g
k =  750 g
v =  1500 ml
s =  12.5 g

Step-by-step explanation:

$$\begin{gathered} q=\frac{10}{4}=\frac{5}{2}=2.5 \\ r=200\cdot q=200\cdot \frac{5}{2}=\frac{200\cdot 5}{2}=\frac{1000}{2}=500\text{g} \end{gathered}$$

$h=150\cdot q=150\cdot \frac{5}{2}=\frac{150\cdot 5}{2}=\frac{750}{2}=375\text{g}$

$h_2=150\cdot q=150\cdot \frac{5}{2}=\frac{150\cdot 5}{2}=\frac{750}{2}=375\text{g}$

$k=300\cdot q=300\cdot \frac{5}{2}=\frac{300\cdot 5}{2}=\frac{1500}{2}=750\text{g}$

$v=600\cdot q=600\cdot \frac{5}{2}=\frac{600\cdot 5}{2}=\frac{3000}{2}=1500\text{ml}$

$s=5\cdot q=5\cdot \frac{5}{2}=\frac{5\cdot 5}{2}=\frac{25}{2}=12.5\text{g}$
