Question

Ice sinks in methanol, but floats on water. From this we can conclude

Answer 1

Answer

The density of ICE is LESS than that of water and more  than methanol

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
