    Question

    A solution contains 40% sugar and the rest water. After

    adding 25 liters of water, we get another solution where the percentage of sugar drops to 20%. This solution is then combined with 15 liters of 100% sugar solution. What will be the ratio of sugar to water in the final mixture?
    A 5: 8 Correct Answer Incorrect Answer
    B 1: 1 Correct Answer Incorrect Answer
    C 2: 5 Correct Answer Incorrect Answer
    D 3: 2 Correct Answer Incorrect Answer
    E 1: 3 Correct Answer Incorrect Answer

    Solution

    Let the initial quantity of the solution = 100y  Sugar = 40y  Water = 60y  {40y}/{60y + 25} = 1/4 160y = 60y + 25  100y = 25  y = 0.25  Sugar = 40y = 10  Water = 60y + 25 = 40  Required ratio = (10 + 15)/{40} = 5: 8
