This is how I tried to solve it:
SG oil = density of oil / density of water
density of oil / density of water = total depth / total depth - depth oil = 0.25
This is the solution that tprh provides:
1. I don't understand their explanation of the interface thing
2. Why is the depth of water y instead of the bottom of the tube?
