Which of the following is the correct empirical formula?

$\frac{ \text {Mode - Mean} }3= \text{Median – Mean}$

$\frac{ \text {Mode - Mean} }{3\times2}= \text{Median – Mean}$

Mode - Mean = Median – Mean

$\frac23$ ( Mode - Mean ) = Median – Mean

Correct option is A

Concept Used:

$Mode−Mean=3(Median−Mean)$ 

Solution:

$Mode−Mean=3(Median−Mean)$

Rearranging this, we get:

\frac{Mode−Mean}3

= Median−Mean

The correct answer is (a) (Mode - Mean)/3= Median – Mean
