Explanation:
Given
Water column height![h=25\ cm](/tpl/images/1398/2035/37e31.png)
After oil is poured, the total height becomes![h'=40\ cm](/tpl/images/1398/2035/324cc.png)
Pressure at the bottom will be the sum due to the water and oil column
Suppose the density of the oil is![\rho=900\ kg/m^3](/tpl/images/1398/2035/c7c0f.png)
Pressure at the bottom
