Solution Y is 40 percent sugar by volume, and solution X is 20 percent sugar by volume. How many gallons of solution X must be added to 150 gallons of solution Y to create a solution that is 25 percent sugar by volume?  Choose the correct choice from the following answers.
A) 37.5	B) 75	C) 150	D) 240	E) 450
Sol Y = 40% sugar---------------------Sol Mix = 25 % sugar-----------------Sol X = 20% sugar   Sol Y = +0.15 than Avg---------------Avg = 0.25------------------------------Sol X = -0.05 than avg   0.15 Y - 0.05 X = 0   0.15 Y = 0.05 X   X/Y = 0.15/0.05=

<output>3</output>
3:1   X:Y:Total= 3:1:4   If Y = 150 Gallons then by ratio X:Y = 3:1   X/150= 3/1   X = 150 * 3=

<output>450</output>
450 Gallons   Ans 450
<result>E</result>
Solution Y is 40 percent sugar by volume, and solution X is 20 percent sugar by volume. How many gallons of solution X must be added to 150 gallons of solution Y to create a solution that is 25 percent sugar by volume?
