The total cost of production at different output levels for a firm are tabulated below. What is the profit-maximizing level of output at a market price of Rs 10?
QTC (Rs)115222327431538649763
5
Let us add the MC column to the table
QTC (Rs)MC (Rs)1151522273275431453876491176314
At an output level of 5, MC =7 < P=10
At an output level of 6, MC =11 > P=10
Hence, the profit is maximum at an output level of 5 because the 6th unit will incur a loss.
