The total cost incurred for 10 units is Rs. 400 and 20 units is Rs. 80...
Given:
Total cost for 10 units = Rs. 400
Total cost for 20 units = Rs. 800

To find: Marginal cost

Formula:
Marginal cost = Change in total cost / Change in quantity

Calculation:
Change in total cost = Total cost for 20 units - Total cost for 10 units
= Rs. 800 - Rs. 400
= Rs. 400

Change in quantity = 20 - 10
= 10

Marginal cost = Change in total cost / Change in quantity
= Rs. 400 / 10
= Rs. 40

Therefore, the marginal cost is Rs. 40.
