$27+N$

It's not really a difficult task in resolving Algebraic word problems

You just have to note this following principles..

$"sum of"$ is same thing as $+$ in Algebra

$"of"$ $color(white)$ is same thing as $xx$ in Algebra

$"is"$ $color(white)$ is same thing as $=$ in Algebra

In this case we have $"the sum of 27 and"$

Note that $->$ The sum of, has already given you a clue that it's $+$

Hence The sum of 27 and N means $27 + N$

Hope this is explicit..
