    A 111 Correct Answer Incorrect Answer
    B 144 Correct Answer Incorrect Answer
    C 166 Correct Answer Incorrect Answer
    D 151 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the consecutive even numbers be: x, x + 2, x + 4, x + 6, x + 8, x + 10, x + 12, x + 14, x + 16.

    According to question: x = 0.80 × (x + 16)

    0.2x = 12.8

    x = 64

    So the desired sum = 64 + 2 + 64 + 14 = 144
