Hello Sree Vardhan,
You may use the concepts of laws of floatation to solve this fluids problem.
Consider mass of the body =m
therefore weight of the body = mg
Now let σ be the density of the object and ρ is the density of the water and V is the volume of the object.
So weight = mg = Vσg
and buoyant force = Vρg
bf=n×weight= Vρg=n*Vσg= σ /ρ = 1/n.
( Specific gravity = density of object /density of water.)
Hence, answer is 1/n.
Hope this helps
Regards
