"When 3 is substracted" can be written as minus 3
"One third of a number" can be written as
(1)/(3) n

"The result is less than 6" can be written as < 6

Therefore we put them up together, the inequality will be

(1)/(3)n-3\ \textless \ 6

Solve for the value of n

(1)/(3)n-3\ \textless \ 6
add both side with 3

(1)/(3)n-3+3\ \textless \ 6+3

(1)/(3)n\ \textless \ 9
multiply both side by 3

$3*\ (1)/(3)n\ \ \textless \ 3 *\ 9$
n < 27

The correct answer is first option

\boxed{\boxed{ (1)/(3)n-3\ \textless \ 6;n\ \textless \ 27 }}
