Correct Answer - Option 2 : 75 %
Given:
Quantity of pure milk = 72 liters
Quantity of water = 24 liters
Formula use:
Quantity of Product = Quantity of pure milk + Quantity of water
Percentage of milk in the product = (Quantity of milk / Quantity of Product) × 100
Calculation:
Quantity of Product = Quantity of pure milk + Quantity of water
⇒ Quantity of Product = 72 + 24
⇒ Quantity of Product = 96 liters
Now,
Percentage of milk in the product = (Quantity of milk / Quantity of Product) × 100
⇒ Percentage of milk in the product = \({72\over 96}×100\)
⇒ Percentage of milk in the product = 75%
Therefore, the percentage of milk in the resultant product is 75%.
Hence, the correct answer is 75%.
