Step 1: Calculate initial water. Initial mixture is 40 liters with 10% water. पानी = 10\% × 40 \, लीटर = 0.10 × 40 = 4 \, लीटर Milk = 40 - 4 = 36 liters. Step 2: Let x liters of water be added. New water = 4 + x liters. New total = 40 + x liters. Step 3: Set up equation for 20% water. 4 + x = 20\% × (40 + x) 4 + x = 0.20(40 + x) Step 4: Expand right side. 4 + x = 8 + 0.20x Step 5: Isolate x. x - 0.20x = 8 - 4 0.80x = 4 x = (4)/(0.80) = 5 liters. Final answer: 5 लीटर
