Question

7. A body floats in water with 40% of its volumeoutside water. When the same body floats in oil,60% of its volume remains outside oil. The relative
density of oil is
(a)0.9
(b)1.2
(c)1.5
(d)1.8​

Answer 1

Explanation:

If you mean petroleum (aka oil for producing gasoline, etc.) the average density is about 800Kg/m3 or 0.8g/cm3. In comparison to water its specific gravity is 0.8. Looking online I see oils ranging from 0.7 to 0.98g/cm3 so most are less dense than water
