Solution

10%

Let the volume of ice-berg is V and its density is ρ. If this ice-berg floats in water with volume Vin inside it, then Vin σg = Vρg

$V_{in} = (\frac{ρ}{σ}) V \Rightarrow V_{out} = V - V_{in} = (\frac{σ - ρ}{σ}) V = (\frac{1000 - 900}{1000}) V = \frac{V}{10} \Rightarrow \frac{V_{out}}{V} = 0.1 = 10 %$
