Question

how much milk should be added in a milk solution to make milk quantity in it 75% if 80l of milk solutions has 45%milk in it​

Answer 1

Answer:400/3 L

Step-by-step explanation: 80L has 45%

                                            xL has 75%

therefore by unitary method

x=(75*80)/45

 =400/3 L

Answer 2

96 liters of milk should be added.

Step-by-step explanation:

Since we have given that

Quantity of milk solution = 80 liter

Percentage of milk = 45%

Percentage of water = 55 %

So, ratio of milk and water would be

$45:55\\\\=9:11$

So, Quantity of milk =$\dfrac{9}{20}\times 80=9\times 4=36\ liters$

Quantity of water = $\dfrac{11}{20}\times 80=11\times 4=44\ liters$

Let the M liters of milk should be added to the milk solution to make it 75% milk.

So, it becomes,

$\dfrac{36+M}{44}=\dfrac{75}{25}=\dfrac{3}{1}\\\\36+M=3\times 44\\\\36+M=132\\\\M=132-36=96$

Hence, 96 liters of milk should be added.
