Answer: 8

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 (x+x+2x+2x+3x+3x)/(6)=8\\\\\Rightarrow (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=}(8+8)/(2)\\\\\Rightarrow \text{Median=}8
