    of 2:1 respectively is mixed with another 120 ml of mixture B containing milk and water in the ratio of 3:5 respectively. Find the ratio of milk to water in the resultant mixture.
    A 25:23 Correct Answer Incorrect Answer
    B 23:25 Correct Answer Incorrect Answer
    C 5:6 Correct Answer Incorrect Answer
    D 6:5 Correct Answer Incorrect Answer
    E 3:4 Correct Answer Incorrect Answer

    Solution

    Quantity of milk in 120 ml of mixture A = 2/3 × 120 = 80 ml
    Quantity of water in 120 ml of mixture A = 1/3 × 120 = 40 ml
    Quantity of milk in 120 ml of mixture B = 3/8 × 120 = 45 ml
    Quantity of water in 120 ml of mixture B = 5/8 × 120 = 75 ml
    Desired Ratio = (80 + 45):(40 + 75) = 125:115 = 25:23
