The correct option is B 13103
Let V be the volume of iceberg and let x be the fraction of volume above water.
Using law of floatation,
Weight of the floating body = Weight of liquid displaced by part of the floating body inside the liquid.
Therefore, Vρiceg=(1−x)Vρwaterg
Using the value of ρice and ρwater, we get
(1−x)=9001030
⇒x=13103
