Solution Y is 30 percent liquid X and 70 percent water. If 2 kilograms of water evaporate from 6 kilograms of solution Y and 2 kilograms of solution Y are added to the remaining 4 kilograms of liquid, what percent of this new solution is liquid X?	Select
A) 33%
B) 35 1/2%
C) 37%
D) 40%
E) 42%
In 8 kilograms of solution Y there are   0.3*6= 
<gadget id="calculator">  0.3*6</gadget>
<output>1.8</output>
1.8 kilograms of solution X;   After 2 kilograms of water are replaced by 2 kilograms of solution Y, to the existing 1.8 kilograms of solution X, 0.3*2=0.6 kilograms of solution X are added, so in the new solution of 6 kilograms there are 1.8+0.6= 
<gadget id="calculator">1.8+0.6</gadget>
<output>2.4</output>
2.4 kilograms of solution X, which is  2.4/6*100= 
<gadget id="calculator"> 2.4/6*100</gadget>
<output>40</output>
40% of this new solution.   Answer: 40%.
<result>D</result>
Solution Y is 30 percent liquid X and 70 percent water. If 2 kilograms of water evaporate from 6 kilograms of solution Y and 2 kilograms of solution Y are added to the remaining 4 kilograms of liquid, what percent of this new solution is liquid X?
