    Answer:

    0.333

    Explanation:

    Weight of the sinker in water = 25gf

    Weight of cork in air and sinker in water = 25gf + 2.5gf

    = 27.5gf

    Weight of the cork and sinker in water = 20gf

    Loss of weight of cork in water = 27.5- 20 = 7.5gf

    Rd of cork = weight of cork in air/ loss of weight of cork in water

    = 2.5/7.5

    = 1/3

    = 0.333

    Hence the Relative density of the cork is 0.333
