A) \[\frac{3}{4}\]
B) \[\frac{4}{9}\]
C) \[\frac{2}{3}\]
D) \[\frac{9}{8}\]
Correct Answer: D
Solution :
Let the volume of the body be V and density be d. Then for the case of water \[V\times d\times g=\frac{3}{4}\times v\times {{d}_{water}}\times g\] For oil \[V\times d\times g=\frac{2}{3}\times V\times {{d}_{oil}}\times g\] \[\Rightarrow \] \[\frac{{{d}_{water}}}{{{d}_{water}}}=\frac{9}{8}\]
