500 kg of milk testing 6.5% fat to be standardized to 3.1% fat using skim milk containing 0.05% fat. Therefore, the quantity of skim milk required to be added to 500 kg whole milk will be?

500 kg of milk testing 6.5% fat to be standardized to 3.1% fat using skim milk containing 0.05% fat. Therefore, the quantity of skim milk required to be added to 500 kg whole milk will be? Correct Answer 557.38 kg

Thus mixing of 3.05 kg of 6.5% fat milk with 3.40 kg of the skim milk will yield 6.45 kg of milk containing the desired fat level i.e. 3.1%. Therefore, the quantity of skim milk required to be added to 500 kg whole milk will be (3.4 x 500)/3.05=3.05. Accordingly, 557.38 kg of 0.05% skim milk mixed with 500 kg of 6.5% fat whole milk will yield 1057.38 kg of milk having 3.1% fat.
