Question

    240 ml of mixture A containing oil and vinegar in the

    ratio of 5:3 respectively is mixed with another 120 ml of mixture B containing oil and vinegar in the ratio of 2:1 respectively. Find the ratio of oil to vinegar in the resultant mixture.
    A 23:13 Correct Answer Incorrect Answer
    B 25:15 Correct Answer Incorrect Answer
    C 21:11 Correct Answer Incorrect Answer
    D 27:17 Correct Answer Incorrect Answer
    E 24:14 Correct Answer Incorrect Answer

    Solution

    Quantity of oil in 240 ml of mixture A = 5/8 × 240 = 150 ml
    Quantity of vinegar in 240 ml of mixture A = 3/8 × 240 = 90 ml
    Quantity of oil in 120 ml of mixture B = 2/3 × 120 = 80 ml
    Quantity of vinegar in 120 ml of mixture B = 1/3 × 120 = 40 ml
    Desired Ratio = (150 + 80):(90 + 40) = 230:130 = 23:13
