You have a 2 litre jug of 3.5% milk (milk that contains 3.5% fat). how much skim milk (0% fat) do you need to add to it to obtain milk which will have 2% fat?

Total amount of skim milk needed to be added = 0.83 liters

Step-by-step explanation:

Required fat in the resultant milk = 2%

Current amount of fat in the milk = 3.5%

So, 1 - 0.57 = 0.43 liters of skim milk to be added per liter to make the quantity of fat 2% in the whole milk.

Quantity of milk present = 2 liters

So, total amount of skim milk needed to be added = 2 × 0.43

                                                                                       = 0.83 liters

can i see the following ?
