Determine the relative density of the solid and of the oil

I think I have already worked out the density of the solid:

Weight of water displaced = 260N - 240N = 20N

20N / 9.8 = 2.0408kg

Water density = 1kg per litre, so there is 2.0408 litres or 2040.8 cm^3

Mass of solid = 260N / 9.81 = 26.5kg

Mass/ Vol = Density = 26.5 / 2040.8 = 0.01299 kg/cm^3

If this is correct so far, how would I go about working the density of the oil, and are these figures measures of "relative density", which I understand to just be a comparison to the density of water?

Thank you!
