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
