I'm not understanding the solution. Please explain it clearly.

Bulk modulu is the ratio of direct stress to the corresponding volumetric strain.

No, it is wrong because bulk modulus is the ratio of shearstress to the shear strain.

Block modules = sherstress/shearstrain.

Here, K=dp/(-dv/v).

K = direct stress/volumetric strain.
