Say a recliner is actually worth $100   If she sells 100 recliners then she earns $10000   After the discount of 20%, she will earn $80 per recliner and she sells 40% more ie.,140 recliners   Hence her sales tields 140*80= 
<gadget id="calculator">140*80</gadget>
<output>11_200</output>
$11200   Increase in sales=11200-10000=$1120   So% increase = 1120*100/10000= 
<gadget id="calculator">1120*100/10000</gadget>
<output>56/5 = around 11.2</output>
11.20%   11.2% is the answer
<result>C</result>
