Iron ore processing has two steps. Smelting and Smithing. A major steel plant on the East coast of India currently has a smelting capacity of $1000$ Metric Tons $/$ Annum and a Smithing capacity of $800$ Metric Tons$/$annum$.$ Given the nature of the business, the firm should keep processing steel continually to be profitable. The availability of war iron ore is therefore critical for the firm$$s survival. The firm operates by importing raw iron ore from Australia. Iron ore is shipped in large vessels where the cargo is heaped in the center of the ship to hold the iron ore. Each ship $($on average$)$ can transport $30$ MT of iron ore, and the trip from Australia to India takes around $2$ months. What is the number of ships the firm should deploy to transport iron ore?

The firm has recently discovered deposits of iron ore in the hinterland of India, reducing its dependence on iron ore imports. If the iron ore mine has a capacity to supply ore at the rate of $300$ MT$/$annum$,$ what is the number of ships they need to deploy for iron ore imports from Australia?
