In what ratio should a mixture of milk and water in the ratio of 3:4 be mixed with another mixture of milk and water in the ratio 5:2 so that the resultant mixture contains equal quantities of milk and water?	Pick:
A) 3:1 B) 3:5 C) 7:8 D) 7:9 E) 9:11
First mixture: milk and water in the ratio of 3x:4x.   Second mixture: milk and water in the ratio 5y:2y.   We want their mixture to have equal quantities of milk and water: 3x + 5y = 4x + 2y --&gt; x/y = 3.   3:1nswer: 3:1.
