Explanation:

The solution is a dilute solution of methanol. It is described as a "40% methanol" concentration which means the solution is 40% of methanol in the solution. In this solution, it is 40% of methanol and 60% of water. If any solution is to be prepared from this model, the solution must have 40% of methanol, hence to prepare a 200 mL of the same model (40%) of methanol solution, the volume of methanol would be 80 mL and the volume of water would be 120 mL.
