It takes 2 hours on the grinding/cutting machine and 3 hours on the sprayer to manufacture a pedestal lamp.

On any day, the sprayer is available for at the most 20 hours and the grinding/cutting machine for at the most 12 hours. The profit from the sale of a lamp is Rs. 25 and that from a shade is Rs. 15.
