Question

    In a 600-gram mixture, the proportion of Component A to Component B is 3:7. If you add 20 grams of Component A and 80 grams of Component B to the mixture, what will be the new ratio of Component B to Component A in the resultant mixture?

    A 5:9 Correct Answer Incorrect Answer
    B 5:2 Correct Answer Incorrect Answer
    C 5:3 Correct Answer Incorrect Answer
    D 5:7 Correct Answer Incorrect Answer

    Solution

    ATQ, Quantity of Component A in mixture = (3/10) × 600 = 180 grams Quantity of Component B in mixture = 600 – 180 = 420 grams According to question, Desired ratio = (420 + 80):(180 + 20) = 5:2
