$27 + N$

Explanation:

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

You just have to note this following principles..

$\text{sum of}$ is same thing as $+$ in Algebra

$\text{of}$ color(white) is same thing as $\times$ in Algebra

$\text{is}$ color(white) is same thing as $=$ in Algebra

In this case we have $\text{the sum of 27 and}$

Note that $\to$ 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..
