The company itself is divided into many sub-business categories such as steak house, jewelry, frozen food, clothing, and so on. Mr. Tarun, the CEO of HSCH, seeks an investment opportunity in jewelry product line.

The machine will cost $15,000,000 with other expenses. The machine will be fully depreciated after 5 years.
