1454. A firm’s average total cost of production is Rs.300 at 5 units of output and Rs.320 at 6 units of output. The marginal cost of producing the 6th unit is

✅ The correct answer is D.
The answer is Total cost for producing 5 units = 300 x 5 = 1500.

Total cost for producing 6 units = 320 x 6 = 1920
Therefore, Marginal cost for producing the 6th unit = 1920-1500 = 420.

This is a mathematical part that is used for the calculation of economics. At the same time, this also talks about production, and average rate of per unit. Wlso, the marginal cost involved for the total production is also taken into account.
