An ice-berg of density 900 kgm - 3 is floating in water of density 1000 kgm - 3 . The percentage of volume of ice-berg outside the water is
Options
- A20   %
- B35   %
- C10   %
- D11   %
Correct answer
C. 10   %
Step-by-step solution
Let the volume of ice-berg is V and its density is ρ . If this ice-berg floats in water with volume V in inside it, then V in σ g = V ρ g σ = density of water ⇒   V in = ρ σ · V ⇒   V out = V - V in = σ - ρ σ   V = 1000 - 900 1000   V = V 10 ⇒   V out   / V = 0 . 1 = 10   %
