  3. Ta = 5N
    TB = 7N
    Ta/TB = Ss-Sa/Ss-Sb
    5/7= Ss-1/Ss-0.85
    5Ss-4.25 = 7Ss-7
    Ss=1.375
    Where, Ss: Specific density of solid body
    Sa: Specific density of water
    SB: Specific density of oil
    Ta: Apparent weight of body in water
    TB : Apparent weight of the body in oil
