% of sugar in water (by mass) is 1000/[1000+2000)×100=33.33
So 33.33% sugar by mass present.
Molar mass of sugar is 342
Number of miles of sugar present =1000/342
Mol=2.92 mol
Molar mass of water is 18
Number of miles of water present =2000/18
Mol= 111.11= 144.03
Total mol =2.92+111.11= 114.03
Mole fraction of sugar = 2.92/144.03 = 0.0256
Mole fraction of water = 111.11/115.03 = 0.9744
