AI explanation

After transferring 150 cc of milk to the cup, the cup contains 150 cc of milk and 500 cc of water. The 150 cc transferred back contains three-tenths milk and seven-tenths water, meaning 105 cc of milk remains in the cup and 105 cc of water enters the glass. The two quantities are equal, giving a ratio of 1 to 1.
