Write the following sets in roster form :
$C = \{ x:x{\rm{ }}$ is a two-digit natural number such that sum of its digits is $8\} $
$C = \{ x:x{\rm{ }}$ is a two-digit natural number such that the sumof its digits is $8\} $
The elements of this set are $17,26,35,44,53,62,71$ and $80$ only.
Therefore, this set can be written in roster form as $C=\{17,26,35,44,53,62,71,80\}$
