Solution

The correct option is B 7.2
A vessel contains oil density =0.8gm/cm3
Mercury density =13.6gm/cm3
Total weight is balanced by the displaced volumes of the two different fluids. Let it s and volume id v and te density is n.
Then the equilibrium condition should be
vmg=v/2(0.8)g+v2×136gn=0.4+6.8=7.2gm/cm3
