The upthrust equals the reduction in weight = 200g. This is equal to the weight of water displaced by the body, so the weight (mass) of water displaced is 200g, The density of water is 1g/cc, so the volume of water displaced = volume of the body = 200cc. The body weighs 500g in air and has a volume ot 200cc, therefore its density is 500g/200cc = 2.5g/cc or a relative density of 2.5

a body cannot "weigh" 500g, because 500g is a unit of mass, not weight!
let's assume the person meant, the weight of a mass of 500g (which is about 5 Newtons).
1.the upthrust is 2 Newtons, the weight of a mass of 200g
2.the upthrust will be equal to the weight of the mass of water displaced. 200g of water weigh 2 Newtons and have a volume of 0.2 liters
3.the solid has a mass of 500g for a volume of 0.2 litres. This is 2.5 times more than the density of water
