Let +p+ = the original cost of the article
+p+%2B+.2p+=+250+
+1.2p+=+250+
+p+=+208.33+
-----------------
Let the percent of his profit
if he sells it for $275 = +k+
+208.33+%2B+k%2A208.33+=+275+
+208.33%2A%28+1+%2B+k+%29+=+275+
+1+%2B+k+=+275%2F208.33+
+1+%2B+k+=+1.32+
+k+=+.32+
His profit would be 32%
