The annual salaries of four men were Rs 5000, Rs 6000, Rs 6500 and Rs 30000

(i) Find the arithmetic mean of their salaries.

(ii) Is this average typical to their salaries?

5000+ 6000+6500 +30000/4

This mean cannot he called as representative value of the series because it is very high than the actual salary of a number of persons. When the value of the item is very low or very high, then it affects the average of the series. In this case, the arithmetic mean cannot be called the representative of the series.
