Explanation

Interpreting the initial ratio as milk to water = 3:2, the 25 litres contain 15 litres milk and 10 litres water. Equalizing the quantities requires x = 5 litres of water, and restoring the original ratio requires y = 7.5 litres of milk, which is 50% more than x.

AI explanation

The initial 25 litre mixture with a milk to water ratio of 3 to 1 contains 18.75 litres of milk and 6.25 litres of water. Adding x litres of water to achieve a 1 to 1 ratio means 6.25 plus x equals 18.75, so x is 12.5 litres, and adding y litres of milk to restore the original 3 to 1 ratio means 18.75 plus y divided by 18.75 equals 3, which makes y equal to 37.5 litres. Therefore, y is 37.5 minus 12.5 all over 12.5, which is 50 percent more than x.
