percentage of milk in the mixture is​

Answer 1

Answer:

Now we have to increase the water percentage to 20%. ... Lets say we added 'x' litres of water in the mixture and quantity of milk remains constant ... Therefore, 1 part is 40/8 = 5L.

Answer 2

Milk Percentage is 80%

Step-by-step explanation:

Milk Quantity = 8 parts

Water Quantity = 2 parts

Mixture Quantity = Sum of Water and Milk Quantity  

= (2 + 8) Parts

= 10 Parts

Quantity of mixture = Quantity of milk + Quantity of water

                                = 2 parts + 8 parts

                                = 10 parts

Milk Percentage in Mixture = $\frac {Milk\ Quantity}{Mixture\ Quantity} \times 100$

                                              =$\frac {8}{10} \times 100$ = 80 %

Water Percentage = 100% - 80%  

                                = 20%
