What are the total fixed cost, total variable cost and total cost of a firm? How are they related?
Total Fixed Cost: This refers to the costs incurred by a firm in order to acquire the fixed factors for production like cost of machinery, buildings, depreciation, etc. In short run, fixed factors cannot vary and accordingly the fixed cost remains the same through all output levels. These are also called overhead costs. Total Variable Cost: This refers to the costs incurred by a firm on variable inputs for production. As we increase quantities of variable inputs, accordingly the variable cost also goes up. It is also called Prime cost or Direct cost and includes expenses like -wages of labour, fuel expenses, etc.
Total Cost (TC): The sum of total fixed cost and total variable cost is called the total cost.
Total cost = Total fixed cost + Total variable cost
TC = TFC + TVC Relationship between TC, TFC, and TVC:
1) TFC curve remains constant throughout all the levels of output as fixed factor is constant in short run.
2) TVC rises as the output is increased by employing more and more of labour units. Till point Z, TVC rises at a decreasing rate, and so the TC curve also follows the same pattern.
3) The difference between TC and TVC is equivalent to TFC.
4) After point Z, TVC rises at an increasing rate and therefore TC also rises at an increasing rate.
5) Both TVC and TFC is derived from TC i.e. TC = TVC + TFC

What is budget line?
Explain why the budget line is downward sloping.
Suppose a consumer wants to consume two goods which are available only in
integer units. The two goods are equally priced at Rs 10 and the consumer’s
income is Rs 40.
(i) Write down all the bundles that are available to the consumer.
(ii) Among the bundles that are available to the consumer, identify those which cost her exactly Rs 40.
Suppose the demand and supply curve of commodity XX in a perfectly competitive market are given by:
qD =700 - p
qs = 500 + 3p for p ≥ 15
= 0 or 0 ≤ p <15
Assume that the market consists of identical firms. Identify the reason behind the market supply of commodity X being zero at any price less than Rs 15. What will be the equilibrium price for this commodity? At equilibrium, what quantity of X will be produced?
How are the equilibrium price and quantity affected when?
(a) Both demand and supply curves shift in the same direction?
(b) Demand and supply curves shift in opposite directions?
