John has 1,210 Dogs in his house. If exactly 40 percent of all dogs in home are tagged, what percent of the untagged dogs must be tagged so that half of all dogs in the home are tagged?
Choose the correct choice from the following choices:	A) 25.5	B) 30.33	C) 33	D) 37	E) 16.6
All dogs =1210   Currently Tagged = 1210*40/100= 
<gadget id="calculator">1210*40/100</gadget>
<output>484</output>
484   So Untagged dogs= 1210 - 484= 
<gadget id="calculator">1210 - 484</gadget>
<output>726</output>
726   Half of all dogs=605   The number of dogs to be tagged to make half of all dogs tagged = 605-484= 
<gadget id="calculator">605-484</gadget>
<output>121</output>
121   So now the question remains - 121 is how much percentage of untagged dogs (726)= 121 * 100 /726   = 16.6%   Answer (16.6)
<result>E</result>
