    Question

    A 250 litres mixture contains only water and phenyl in

    the ratio 4:1, respectively. If 55 litres of this mixture is replaced with 26 litres of alcohol, then what will be the ratio of quantity of water to that of alcohol in the resultant mixture?
    A 5:1 Correct Answer Incorrect Answer
    B 2:1 Correct Answer Incorrect Answer
    C 7:1 Correct Answer Incorrect Answer
    D 6:1 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Initial quantity of water in the mixture = 200 × (4/5) = 200 litres After removing 55 litres of the mixture, quantity of water = (250 – 55) × (4/5) = 195 × (4/5) = 156 litres Therefore required ratio = 156:26 = 6:1
