He bought some B liters of milk at 60 P money units, and added liters of water. The mixture is liters containing the B liters of milk.

His revenue upon selling all of his mixture is P money units.

Summarize:
Cost = P units
Revenue = P units
Profit = of P money units

Profit percentage based on revenue woould be , if that was what you meant; which you can simplify and compute.

If you meant, based on cost, then divide profit by cost, and then multiply by 100.
