Answer» Answer: 1/6 Step-by-step explanation: Assume 5l mix x l mixter is removed. 2x/5 water + 3X/5 milk remaining (2 - 2x/5) water + (3 - 3x/5) milk x l water is added (2 - 2x/5 + x) water + (3 - 3x/5) milk new ratio = 1:1 (2 - 2x/5 + x) = (3 - 3x/5) => 10 - 2x + 5x = 15 - 3x => 6X = 5 => x = 5/6 l in 5l ---> 5/6 l is removed => 1l ---> 1/6 l is removed |
