the buoyant force acts on a body which is floacting in liquid and the direction of this force is upwards. that means buoyant force acts just opposite to the weight of the body.

Because of this the apparent weight of body floating in liquid is less than the actual weight. 

the relationship among these three is

Buoyant force = actual weight - apparent weight

or 

apparent weight  = true weight - buoyant force

Note :

if the density of the body is less than the body doesnt get immersed in the liquid completly but only a part of it gets inside the liquid we can calculate this part by equating the buoyant force with the weight of the body.
