    observations is 130. Find the mode of the observations.
    A 128 Correct Answer Incorrect Answer
    B 142 Correct Answer Incorrect Answer
    C 140 Correct Answer Incorrect Answer
    D 136 Correct Answer Incorrect Answer

    Solution

    Mean of 15 observations = 124
    Median of 15 observations = 130
    Since,
    Mode = 3*median - 2*mean
    = 3*130 - 2*124 = 390 – 248 = 142
