Bill made a profit of 10% by selling a product. If he had purchased that product for 10% less and sold it at a profit of 30%, he would have received $ 63 more. What was his original selling price?	Choices:
A) $770  B) $660  C) $700  D) $990  E) $840
Let the original purchase price be X   So original selling price at 10% profit = 1.1X   If product is purchased at 10% less of original = 0.9X   Profit of 30% on this price = 1.3(0.9X)   He would have received $63 more in second scenario =&gt; 1.3(0.9X) - 1.1X = 63   =&gt; 0.07X = 63   =&gt; X = $900   Original purchase price = $900   Hence, original selling price (at 10% of profit) = 1.1(900) = $990   Option $990
