question

The temperatures of three different liquids are maintained at 15°C, 20°C, and 25°C, respectively. When equal masses of the first two liquids are mixed, the final temperature is 18°C, and when equal masses of the last two liquids are mixed, the final temperature is 24°C. What tempera-ture will be achieved by mixing equal masses of the first and the last liquid?
