Question

Find the mean of the data when it us given that mode is 50.5 and median is 45.5

Answer 1

mode=3median+2mode
50.5=45.5(3)+2mode
50.5-136.5/2=mode
86/2=mode
43=mode

Answer 2

Answer:

Mean = 35.5

Step-by-step explanation:

The relation between mean, median and mode is given by

Mean – Mode = 3 (Mean – Median)

Here, Mode = 50.5

Median = 40.5

Let, mean be M .

So, by substituting the values, we get

M - 50.5  = 3(M - 40.5)

Or, M - 50.5 = 3M - 121.5

⇒ 121.5  - 50.5 = 3M -M

⇒  2M = 71

or, M = 35.5

Hence, Mean = 35.5
