Question

I have the fallowing question and solution from a reeds naval arc book. Im just confused as to where this answer came from and the formulas used. Wondering if i could have this answer/ solution broken down and explained in detail.  

 A ship of 7000 tonne displacement has a waterplane area
of 1500 m2. In passing from sea water into river water of
1005 kg/m3 there is an increase in draught of 10 cm. Find the I
density of the sea water. 

picture of the "answer" is attached
