At the end of the day, February 14th, a florist had 90 roses left in his shop, all of which were red, white or pink in color and either long or short-stemmed. A third of the roses were short-stemmed, 15 of which were white and 10 of which were pink. The percentage of pink roses that were short-stemmed equaled the percentage of red roses that were short-stemmed. If none of the long-stemmed roses were white, what percentage of the long-stemmed roses were red?  Pick one
A) 20%	B) 75%	C) 50%	D) 33.3%	E) 80%
R + W + P = 90   S + L = 90   1/3 * 90= 
<gadget id="calculator">1/3 * 90</gadget>
<output>30</output>
30   Short-Stemmed White= 15   Short-Stemmed Pink = 10   =&gt; Short-Stemmed Red = 5   10/P = 5/R   =&gt; R = P/2 , P=2R   So Total Long Stemmed = 60   And Long Stemmed Red + Long Stemmed Pink = 60   So Long Stemmed Red/Long Stemmed = ?   Total White = 15 (As no Long stemmed white)   =&gt; R + 2R + 15 = 90   =&gt; 3R = 75 and R = 25   Long Stemmed R = 25 - 5= 
<gadget id="calculator">25 - 5</gadget>
<output>20</output>
20   So Long Stemmed Red/R= 20/60 = 33.3%   Answer - 33.3%
<result>D</result>
