- If the solid with a density of 900 kg/m³ is able to float in the oil and the oil, in turn, floats on water with a density of 1000 kg/m³, then indeed the density of the oil must be between the densities of the solid and the water.
- A solid of density 900 kg/m3 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/m3 to1000 kg/m3.
- Therefore, the density of oil could be 950 kg/m3.
- This density would allow the solid to float in the oil, and the oil would float on the water.
Thus, A solid of density 900 kg/m3 floats in oil. The oil floats on water of density 1000 kg/m3. The density of oil in kg/m3 could be 950 kg/m3.

Understanding the Problem
To determine the density of the oil in which the solid floats, we need to consider the principles of buoyancy.
Key Concepts
- Buoyancy Principle: An object floats when the weight of the fluid displaced is equal to the weight of the object.
- Densities Involved:
- Density of the solid = 900 kg/m3
- Density of water = 1000 kg/m3
- Density of oil = ? (to be determined)
Analyzing the Situation
1. Floating Conditions:
- For the solid to float in oil, the oil's density must be less than the density of the solid, as it is floating on the oil.
- The oil itself must be less dense than water in order to float on it.
2. Density Relationships:
- Since the solid has a density of 900 kg/m3, the density of oil must be greater than 900 kg/m3 for the solid to float.
- The oil must also be less dense than water (1000 kg/m3).
Determining the Density of Oil
Given the constraints:
- The oil density must satisfy: 900 kg/m3 < density="" of="" oil="" />< 1000="" />
The possible options for the density of oil are:
- a) 950 kg/m3
- b) 850 kg/m3
- c) 800 kg/m3
- d) 1050 kg/m3
Among these options, only 950 kg/m3 fits the requirement of being greater than 900 kg/m3 (to support the solid) and less than 1000 kg/m3 (to float on water).
Conclusion
Therefore, the correct answer for the density of oil is option a) 950 kg/m3.
