    128 litres of mixture β€˜A’ (milk + water) contains 32

    litres more water than milk. If 25% of mixture β€˜A’, 70 litres of milk and 80 litres of water are added in an empty jar, then the quantity of milk is what percentage of the quantity of water in the jar?
    A 72% Correct Answer Incorrect Answer
    B 62% Correct Answer Incorrect Answer
    C 82% Correct Answer Incorrect Answer
    D 92% Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the quantity of milk in mixture β€˜A’ = β€˜y’ litres Then, quantity of water in mixture β€˜A’ = (y + 32) litres So, y + y + 32 = 128 Or, 2y = 128 – 32 = 96 Or, y = 96/2 = 48 So, quantity of milk in mixture β€˜A’ = 48 litres And, quantity of water in mixture β€˜A’ = 48 + 32 = 80 litres Quantity of milk in 25% of mixture β€˜A’ = 48 Γ— 0.25 = 12 litres Quantity of water in 25% of mixture β€˜A’ = 80 Γ— 0.25 = 20 litres So, quantity of milk in the jar = 12 + 70 = 82 litres Quantity of water in the jar = 80 + 20 = 100 litres So, required percentage = (82/100) Γ— 100 = 82%
