The following table shows the total cost schedule of a competitive firm. It is given that the price of the good is Rs 10. Calculate the profit at each output level. Find the profit maximising level of output.
Output | TC (Rs.) |
---|---|
0 1 2 3 4 5 6 7 8 9 10 |
5 15 22 27 31 38 49 63 81 101 123 |
Quantity Sold |
Price | TC | TR = P x Q | Profit = TR - TC |
---|---|---|---|---|
0 | 10 | 5 | 10x0=10 | 0 - 5 = -5 |
1 | 10 | 15 | 10x1=10 | 10 - 15 = -5 |
2 | 10 | 22 | 10x2=20 | 20 - 22 = -2 |
3 | 10 | 27 | 10x3=30 | 30 - 27 = 3 |
4 | 10 | 31 | 10x4=40 | 40 - 31 = 9 |
5 | 10 | 38 | 10x5=50 | 50 - 38 = 12 |
6 | 10 | 49 | 10x6=60 | 60 - 49 = 11 |
7 | 10 | 63 | 10x7=70 | 70 - 63 = 7 |
8 | 10 | 81 | 10x8=80 | 80 - 81 = -1 |
9 | 10 | 101 | 10x9=90 | 90 - 101 = -11 |
10 | 10 | 123 | 10x10=100 | 100 - 123 = -23 |
Profit maximising output is where the difference between TR and TC is the maximum. This exists at 5 units of output, where firm is earning profit of Rs 12.
The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.
A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?

Compute the total revenue, marginal revenue and average revenue schedules in the following table. Market price of each unit of the good is Rs 10.
Quantity Sold | TR | MR | AR |
---|---|---|---|
