Question

A body floats with two-thirds of its volume outside water and $(3/4{)}^{th}$ of its volume outside another liquid. The density of the other liquid will be:

• A. $\left(9/4\right)gm/cc$
• B. $4.0gm/cc$
• C. $\left(8/3\right)gm/cc$
• D. $\left(4/3\right)gm/cc$

Answer 1

Answer: (B)

$4.0gm/cc$

volume of body inside the $liqui{d}_1=1/3rd$ of total volume

volume of body inside the $liqui{d}_2=1/4th$ of total volume

density of liquid$=\left(1/3\right)/\left(1/4\right)=4/3gm/cc$
