Question

Mode=400 and median=500 find mean

Answer 1

Here is your answer buddy,

$\textbf{Given}$

Mode = 400
Median = 500

$\textbf{Now}$

We need mean.

So, We know that,

$\textbf{Mean - Mode = 3(Mean - Median)}$

Now, as per question,

Mean - 400 = 3(Mean - 500)

=> Mean - 400 = 3Mean - 1500
=> Mean - 3Mean = -1500 + 400
=> - 2Mean = -1100
=> Mean = $\textbf{550}$
( Minus and Minus get cancelled)

Hope this helps you.
