A mixture contains milk and water in the ratio 5 : 1. On adding 5 liters of water, the ratio of milk and water becomes 5 : 2. What is the quantity of milk in the mixture?

प्रारंभिक अनुपात: 5x और 1x। केवल पानी मिलाया गया है। नया पानी = x + 5। अनुपात: 5x / (x+5) = 5/2 => 10x = 5x + 25 => 5x = 25। दूध (5x) = 25 लीटर।
