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 $ 49 more. What was his original selling price? Choose the correct choice from the following 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 $49 more in second scenario =&gt; 1.3(0.9X) - 1.1X = 49   =&gt; 0.07X = 49   =&gt; X = $700   Original purchase price = $700   Hence, original selling price (at 10% of profit) = 1.1(700) = $770   Option $770
