An object when placed in water floats with one-third of its volume outside water. If it is placed in a liquid 'X', it floats with $\frac{3}{4}$ of its volume outside the liquid. Density of the liquid
'X' is:

• A

  $\frac{8}{3} \mathrm{gm}/\mathrm{cc}$

• B

  $\frac{7}{2} \mathrm{gm}/\mathrm{cc}$

• C

  $\frac{11}{3} \mathrm{gm}/\mathrm{cc}$

• D

  $\frac{17}{5} \mathrm{gm}/\mathrm{cc}$
