If \( Y \) is directly related to \( X \), we can express this relationship as:

\[
Y = kX
\]

where \( k \) is the constant of variation.

We are given that \( Y = 81 \) when \( X = 27 \). We can use this information to find \( k \):

\[
81 = k \cdot 27
\]

To solve for \( k \), divide both sides by 27:

\[
k = \frac{81}{27} = 3
\]

Thus, the constant of variation \( k \) is \( 3 \).
