Let the marked price be \( M \). The shopkeeper sells the article at \( M - 12.5% \) of \( M \).
After giving the discount, the selling price will be \( 0.875M \).
Since the shopkeeper earns a profit of 15%, the selling price will also be \( 1.15 \times 385 \).
So, we set up the equation:
\[
0.875M = 1.15 \times 385
\]
Solving this gives \( M = 484 \).
Thus, the correct answer is 484.
