Answer 1

Explanation:

Given that the mean of the numbers is 12

`mean = (sum \: \: of \: observations)/(total \: number \: of \: observations)`

so here

let's that one as x and another one as 2x since it is given that one is twice the other

Therefore we get

`mean = (13 + x + 4 + 16 + 6 + 2x)/(6)`

Given mean = 12

`12 = (39 + 3x)/(6)`

`72 = 39 + 3x`

`3x = 33`

`x = 11`

Hence it's 11 and 22
