Choose the most appropriate option:
A) 10%
B) 15%
C) 20%
D) 28%
E) 50%
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 60% more ie.,160 recliners   Hence her sales tields 160*80= 
<gadget id="calculator">160*80</gadget>
<output>12_800</output>
$12800   Increase in sales=12800-10000= 
<gadget id="calculator">12800-10000</gadget>
<output>2_800</output>
$2800   So% increase= 2800*100/10000= 
<gadget id="calculator">2800*100/10000</gadget>
<output>28</output>
28%   28% is the answer
<result>D</result>
