      Question

      Mixture 'A' contains 20% water and rest milk which is equal to 60% of quantity of water in mixture 'B' (milk + water). Ratio of quantity of milk in mixture 'A' and mixture 'B' is 2:3, respectively. If difference between total quantity of mixture 'A' and mixture 'B' is 184 litres, then find the difference between quantities of water in given two mixtures.

      A 128 litres Correct Answer Incorrect Answer
      B 110 litres Correct Answer Incorrect Answer
      C 138 litres Correct Answer Incorrect Answer
      D 150 litres Correct Answer Incorrect Answer
      E 120 litres Correct Answer Incorrect Answer

      Solution

      Let quantity of water in mixture 'B' be '5x' litres Quantity of milk in mixture 'A' = 0.6 Γ— 5x = '3x' litres Total quantity of mixture 'A' = (3x/0.8) = 3.75x litres Quantity of water in mixture 'A' = (3.75x βˆ’ 3x) = 0.75x litres Quantity of milk in mixture 'B' = (3x Γ— 3/2) = 4.5x litres Total quantity of mixture 'B' = (5x + 4.5x) = 9.5x According to the question, (9.5x βˆ’ 3.75x = 184) Or, (5.75x = 184) Or, x = 32 Required difference = 5x βˆ’ 0.75x = 4.25x = 4.25 Γ— 32 = 136 litres
