Answer»

If the Arithmetic mean of a series is 45 and the median is 40, then CALCULATE the value of the mode of that series.

Step-by-step explanation:

  • ACCORDING to Karl Pearson's empirical relationship,
  • To find the mean, median, and mode, the FORMULA is

                  Mean - Mode = 3(Mean - Median)

Given, Mean = 45

           Median = 40

Substituting the values,

     ⇒ 45 - Mode = 3(45 - 40)

          45 - Mode = 3(5)

          45 - Mode = 15

           Mode = 45 -15

           Mode = 30

Therefore, the mode of the series is 30.
