Can anybody help me on this one

A ship sails from sea water into fresh water and therefore sinks slightly.When its load of 600000kg is removed,its returns to its original level.Assuming the sides of the ship are vertical at the water line,find the mass of ship before it was unloaded.

I fail to understand because we don't have the weight of the ship.

You need the ratio R of the densitiy of ocean water to fresh water.

(W+600000)/W=R

Of course, if you look up R and then solve for W, it will be the answer to your question! Do you see why?
