Quantity of milk in 180 ml of mixture = 180 × 15/(15 + x) Quantity of water in 180 ml of mixture = 180 × x/(x + 15) According to question; {2700/(15 + x) + 65}/{180x/(x + 15) + 55} = 2/1 Or, 2700/(15 + x) + 65 = 360x/(x + 15) + 110 Or, (2700 – 360x)/(x + 15) = 45 Or, 2700 – 360x = 45x + 675 Or, 405x = 2025 Or, x = 5
