Solution A contains 15% bleach per liter and solution B contains 45% bleach per liter. If solution A and solution B are mixed in a 1 to 1 ratio, what fraction of the mixed solution is NOT bleach?	Select the correct option:	A) 1/3	B) 7/10	C) 2/5	D) 1/4	E) 2/3
Amount of bleach in solution A: 15/100   Amount of bleach in solution 7/10: 45/100   Amount of bleach in 1 liter of mixed solution: 1/2 x (15/100) + 1/2 x (45/100) = 60/200 = 3/10   Amount of solution that is not bleach: 1-3/10=7/10   Answer is 7/10
