The concentration of spirit in three different vessels A, B and C are 45%, 30% and 12% respectively. If 4 litres from vessel A, 5 litres from vessel B and 6 litres from vessel C are mixed, find the concentration of spirit in the resultant solution. Choose the correct choice from the following choices:  A) 32.80%  B) 26.80%  C) 34%  D) 24.62%  E) 36%
Quantity of spirit in new solution=(4*45/100)+(5*30/100)+(6*12/100)=1.8+1.5+0.72= 
<gadget id="calculator">1.8+1.5+0.72</gadget>
<output>4.02</output>
4.02 liters   So % concentration of spirit=100*4.02/(4+5+6)= 
<gadget id="calculator">100*4.02/(4+5+6)</gadget>
<output>26.8</output>
26.80%   ANSWER:26.80%
<result>B</result>
