In a thermally insulated environment, there is water with a mass of 200 gr at 20 degrees Centigrate.We drop 60 grams of ice into the water with a temperature of -40 degrees. If thermal equilibrium is maintained find the mass of ice and water in the environment?

I found the answer as:

60.0.5.10+m80=200.1.20

m of ice=35 and mass of water is 225.

According to tthe book answer is 25 and 235.
