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 $ 56 more. What was his original selling price?	Choices
A) $770  B) $660  C) $700  D) $1100  E) $880
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 $56 more in second scenario =&gt; 1.3(0.9X) - 1.1X = 56   =&gt; 0.07X = 56   =&gt; X = $800   Original purchase price = $800   Hence, original selling price (at 10% of profit) = 1.1(800) = $880   Option $880
