In the given data, the class intervals are equal, i.e. 10. Hence, it can be assumed that class intervals of open-end classes are also equal to 10. This implies that the lower limit of the first class-interval is zero (i.e. 0–10) and the upper limit of the last class interval is 50 (i.e.40–50).

Thus, the arithmetic mean can be calculated by arranging the frequency distribution.
