    A milkman makes 20% profit by selling milk mixed with

    water at Rs.8 per litre. If the cost price of pure milk is Rs. 10 per litre then the ratio of milk and water in the given mixture.
    A 2:1 Correct Answer Incorrect Answer
    B 1:2 Correct Answer Incorrect Answer
    C 1:3 Correct Answer Incorrect Answer
    D 3:1 Correct Answer Incorrect Answer

    Solution

    Cost price of 1 liter mixture = 8 x 100/120 = Rs.20/3 Cost of water = Rs. 0 It means in the mixture there is only milk's cost which is Rs.20/3. Remaining cost = Rs. (10-20/3) = Rs. 10/3 Water/milk = cost of water which is mixed in place of milk/cost of milk which is mixed Water/milk = (10/3)/ (20/3) = 1/2 Milk water = 2:1 The ratio of milk and water is 2:1.
