Alright. Let us first find the mass of sample=31.6-30.32=1.28grams. Meaning water is included in this mass, because it then dries. So to concretize the mass of water in sample is 31.6-31.54=0.06grams.
Let us use ratio and proportion:
Mass of sample:100%
Mass of water:x
Then x =mass of water*100/mass of sample=0.06*100/1.28=4.69%
