A solid of density $900\ kg/m^3$ floats in oil as shown in the given diagram. The oil floats on water of density $1000\ kg/m^3$ as shown. The density of oil in $kg/m^3$ could be:
(a) 850
(b) 900
(c) 950
(b) 1050
"
A solid of density $900\ kg/m^3$ floats in oil as the density of solid is less than that of oil.
And the oil floats in water as its density is less than that of water. so, the density of oil must be between $900\ kg/m^3$ to $1000\ kg/m^3$.
So, the density of oil could be $950\ kg/m^3$.
Therefore, option (c) is correct.
