Question

If for any frequency distribution, the median is 10 and the mode is 30, then approximate value of mean is equal to:

Answer 1

Answer:

mean= (3median-mode)/2

mean=( 3*10-30)/2

mean=0

Answer 2

Answer:

The value of Mean is 0.

Step-by-step explanation:

We have :

Mode = 30 & Median = 10

We know the direct formula

3 Median - 2 Mean = Mode

If we assume the mean to be x then when we substitute the given values we get:

$3(10)-2x=30\\30-2x=30\\-2x=30-30\\-2x=0\\x=0$

So we get the value of Mean as 0
