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 $ 70 more. What was his original selling price? Answers:	A) $770	B) $660	C) $700	D) $1100	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 $70 more in second scenario =&gt; 1.3(0.9X) - 1.1X = 70   =&gt; 0.07X = 70   =&gt; X = $1000   Original purchase price = $1000   Hence, original selling price (at 10% of profit) = 1.1(1000) = $1100   Option $1100
