      It's not that the water really becomes the solute, The mass percent could also be of the solvent rather than the solute. Water will not be solute. The solute is always the one in lower quantity. Don't write it in the exam that water becomes the solute

      To get the v% ,you have to first get the volume of solution.which is volume of solute + volume of solvent,i.e 150ml volume of solvent plus 25ml volume of soulute.. although methanol and water are substances that can be used in dissolving i.e they can both be seen as solvent.But, since the volume of water in this case is higher than that of methanol,he simply made methanol the solute and water the solvent.
