    C 84 Correct Answer Incorrect Answer
    D 70 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    Let the three numbers be 6x, 9x, and 14x, respectively.
    ATQ,
    (6x+14x)−(6x+9x)=30
    20x−15x=30
    5x=30
    x=6
    Therefore, the largest number = 14x = 14 × 6 = 84
