    Mean of remaining

    94 observation = 240.1277

    Approximately = 240

    Step-by-step explanation:

    First the mean of the data with 100 observation is 267, so the summation of the set of data is equall to 267*100 = 26700

    Now we have six outliers with mean of 688, so total summation of the outliers = 688*6 = 4128

    The mean of the remaining set of data with (100-6) = 94 observation is

    (26700-4128) / 94 = 22572/94

    Mean of 94 observation = 240.1277

    Approximately = 240
