Jug contains water and orange juice in the ratio 5:7 . another jug contains water and orange juice in ratio 7 : 2 . In what proportion should these 2 liquids be mixed to give a water and orange juice in ratio 3 : 4	Select
A) 4 : 5 B) 85 : 3 C) 88 : 3 D) 2 : 3 E) 87 : 7
Let x ml of Jug 1 be mixed with y ml of jug 2   5x/12 + 7y/9 = 3/7*(x+y)   7x/12 + 2y/9 = 4/7 *(x+y)   =&gt; (15x + 28y)/36 = 3/7 * (x+y)   =&gt; 105x + 196y = 108x + 108y   =&gt; 88y - 3x = 0   =&gt; x/y = 88/3   Answer - 88 : 3
