As,the wooden block floats with #2/5# th of its volume outside glycerine,the buoyancy force exerted by glycerine on the #3/5# th of its volume just balances its weight.

So,if the density of the block is #rho#,and #d# is of glycerine,then,

# v*rho*g = 3/5 *d*g#

so, #d/rho=5/3#

So,relative density of glycerine w.r.t wooden block is #5/3#
