Three tubs filled with water. One hot, one roomtemp, one cold. Each tub has 60 liters of water in them. We take 30 L from the roomtemp tub and pour it into the hot tub. Take 30 L from the roomtemp tub again and pour it into the cold tub. Take 30 L from the hot tub and pour it into the roomtemp tub. Take another 30 L from the cold tub and pour it into the roomtemp tub. How much water in each tub and what temp?
