Solution Y is 30 percent liquid X and 70 percent water. If 4 kilograms of water evaporate from 8 kilograms of solution Y and 4 kilograms of solution Y are added to the remaining 6 kilograms of liquid, what percent of this new solution is liquid X?	Choose the correct choice from the following:  A) 40%  B) 41 1/2%  C) 44%  D) 45%  E) 46%
In 8 kilograms of solution Y there are   0.3*8= 
<gadget id="calculator">  0.3*8</gadget>
<output>2.4</output>
2.4 kilograms of solution X;   After 4 kilograms of water are replaced by 4 kilograms of solution Y, to the existing 2.4 kilograms of solution X, 0.3*4=1.2 kilograms of solution X are added, so in the new solution of 8 kilograms there are 2.4+1.2= 
<gadget id="calculator">2.4+1.2</gadget>
<output>3.6</output>
3.6 kilograms of solution X, which is  3.6/8*100= 
<gadget id="calculator"> 3.6/8*100</gadget>
<output>45</output>
45% of this new solution.   Answer: 45%.
<result>D</result>
Solution Y is 30 percent liquid X and 70 percent water. If 4 kilograms of water evaporate from 8 kilograms of solution Y and 4 kilograms of solution Y are added to the remaining 6 kilograms of liquid, what percent of this new solution is liquid X?
