Answer 1

Step-by-step explanation:

Given that the mean of the numbers is 12

$mean = \frac{sum \: \: of \: observations}{total \: number \: of \: observations}$

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

$mean = \frac{13 + x + 4 + 16 + 6 + 2x}{6}$

Given mean = 12

$12 = \frac{39 + 3x}{6}$

$72 = 39 + 3x$

$3x = 33$

$x = 11$

Hence it's 11 and 22
