The mean of 6 numbers is 8.

shutvik [7]

Answer: 8

Step-by-step explanation:

Given

Mean of the numbers is 8

If the ratio is 1:1:2:2:3:3

Suppose the numbers are $x, x, 2x, 2x, 3x, 3x$

Write the mean of the numbers

$\Rightarrow \dfrac{x+x+2x+2x+3x+3x}{6}=8\\\\\Rightarrow \dfrac{12x}{6}=8\\\\\Rightarrow x=4$

So, the numbers are $4, 4, 8,8 ,12,12$

As the total numbers are even, median is the sum of the middle values

$\Rightarrow \text{Median=}\dfrac{8+8}{2}\\\\\Rightarrow \text{Median=}8$
