    Answer: 11%

    Explanation:

    Given that

    X = ab^2/C. Calculate percentage error in X, when percentage error in a, b, c are 4,2 and 3 respectively.

    Percentage error of b = 2%

    Percentage error of b^2 = 2 * 2 = 4

    When you are calculating for percentage error that involves multiplication and division, you will always add up the percentage error values.

    Percentage error of X will be;

    Percentage error of a + percentage error of b^2 + percentage error of c

    Substitute for all these values

    4 + 4 + 3 = 11%

    Therefore, percentage error of X is 11%
