    Question

    A 250 litres mixture contains only water and phenyl in

    the ratio 3:2, respectively. If 60 litres of this mixture is replaced with 90 litres of alcohol, then what will be the ratio of quantity of water to that of alcohol in the resultant mixture?
    A 12:17 Correct Answer Incorrect Answer
    B 17:15 Correct Answer Incorrect Answer
    C 19:15 Correct Answer Incorrect Answer
    D 21:17 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Initial quantity of water in the mixture = 250 × (3/5) = 150 litres After removing 60 litres of the mixture, quantity of water = (250 – 60) × (3/5) = 190 × (3/5) = 114 litres Therefore required ratio = 114:90 = 19:15
