Explanation

Pot 1: Milk:Water = 4:1 (5 parts total). Pot 2: 5:2 (7 parts). Pot 3: 6:1 (7 parts). Equal mixtures means equal volumes. LCM of 5, 7, 7 is 35. In 105 units: Pot 1 gives 84 milk + 21 water. Pot 2 gives 75 milk + 30 water. Pot 3 gives 90 milk + 15 water. Total: 84+75+90 = 249 milk, 21+30+15 = 66 water. Ratio = 249:66 = 83:22 after dividing by 3.
