A) \[3,\text{ }2\]
B) \[2,\frac{3}{4}\]
C) \[\frac{3}{2},2\]
D) \[4,\text{ }3\]
E) \[3,\frac{3}{2}\]
Correct Answer: E
Solution :
Relative density of solid \[=\frac{weight\text{ }in\text{ }air}{weight\text{ }in\text{ }air-weight\text{ }in\text{ }water}\] \[\Rightarrow \] Relative density of solid \[=\frac{120}{120-80}=\frac{120}{40}=3\] Relative density of liquid \[=\frac{weight\text{ }in\text{ }air-weight\text{ }in\text{ }liquid}{weight\text{ }in\text{ }air-weight\text{ }in\text{ }water}\] \[\Rightarrow \]Relative density of liquid \[=\frac{120-60}{120-80}=\frac{60}{40}=\frac{3}{2}\]
