Question

If arithmatic mean of a series 45 and median 40 .then calculate the value of mode ?​​

Answer 1

the answer will be 30..........

Answer 2

Given:

Arithmetic mean of the series = 45

Median of the series = 40

To find:

The value of mode of the series.

Solution:

From the Karl Pearson's empirical relationship we know that:

Mean - Mode = 3(Mean - Median)

Putting the values we get:

45 - mode = 3(45 - 40)

45 - mode = 15

mode = 45- 15

mode = 30

Therefore the value of mode of the series will be 30.
