    Answer: Upthrust = Weight – Apparent weight

    = 0.250 kgf – 0. 150 kgf

    = 0.100 kgf

    Density = mass / volume

    volume = mass / density

    = 0.100 kg / (1000 kg / m³)

    = 0.0001 m³

    density of object  = mass / volume

    = 0.250 kg / 0.0001 m³

    = 2500 kg / m³

    upthrust of oil = Weight – Apparent weight

    = 0.250 kgf – 0.125 kgf

    = 0.125 kgf

    density = mass / volume

    = 0.125 kg / 0.0001 m³

    = 1250 kg/m³

    density of the object = 2500 kg / m³

    density of oil = 1250 kg / m³
