In a mixture of 80 litres of milk and water, 25% of the mixture is milk. How much water should be added to the mixture so that milk becomes 20% of the mixture?
20 litres
30 litres
25 litres
24 litres
15 litres
Total Mixture = 80L
Milk = 80 x 0.25 => 20L
Water = 60L
As per the question,
Total Quantity x 20/100 = 20
Total Quantity = 100L
Quanity Increased/Water Added = 100-80 => 20L
