A farmer harvests \(10\) tonnes of fresh cassava roots with an initial moisture content of \(65\)% (wet basis). The roots must be dried to \(12\)% moisture for safe storage. The dryer removes moisture at a rate of \(0.8\) kg water per hour per tonne of fresh roots and operates \(8\) hours per day. The dryer consumes \(5\) kW of power and electricity costs \(\u20A6\)150 per kWh. \n\nCalculate (a) the total drying time in days, (b) the total energy cost, and (c) the net profit if the market price of dried cassava is \(\u20A6\)200 per kg and the farmer's production cost (excluding drying) is \(\u20A6\)500 per tonne of fresh roots. Assume no loss other than moisture removal.

Answer Options

A. Drying time ≈ 85 days; Energy cost ≈ \u20A6550,000; Net profit ≈ \u20A6240,000
B. Drying time ≈ 90 days; Energy cost ≈ \u20A6600,000; Net profit ≈ \u20A6220,000
C. Drying time ≈ 100 days; Energy cost ≈ \u20A6630,000; Net profit ≈ \u20A6210,000
Correct Answer D. Drying time ≈ 95 days; Energy cost ≈ \u20A6565,000; Net profit ≈ \u20A6226,000
Correct Answer
D
Correct Option:
Drying time ≈ 95 days; Energy cost ≈ \u20A6565,000; Net profit ≈ \u20A6226,000
