Question

    If the average of 19, 34, 67, 45, 28, and 'x' is 43,

    determine the value of 'x²'.
    A 3010 Correct Answer Incorrect Answer
    B 2520 Correct Answer Incorrect Answer
    C 4225 Correct Answer Incorrect Answer
    D 3621 Correct Answer Incorrect Answer

    Solution

    ATQ,

    19 + 34 + 67 + 45 + 28 + x = 43 × 6

    Or, x = 258 - (19 + 34 + 67 + 45 + 28)

    So, x = 65

    So, required value = 65² = 4225
