List of top Economics Questions on Cost Function and Marginal Cost asked in CUET (PG)

Consider the following statements: A. Average Fixed Cost always decline with increase in output, B. Marginal Cost intersects AVC and ATC at their minimum point, C. Learning Curve implies cost rises with accumulated output, D. In the long run, all costs are variable, E. Longrun Average Cost is envelope of Shortrun Average Cost curves.

If \(TC=\frac{Q^3}{3}+20\), what will be \(MC\)?

Derivative of Average cost \((AC)=5+\frac{2}{Q}\) is:

Total cost curve of a firm is a

For a manufacturing firm, the cost function is given by \(C = q^{3} + 2q^{2} + q + 1.\) The marginal and average costs at \(q = 10\) units are respectively given by:

Given a cubic cost function C(Q) = Q³ + Q² + Q + 1, arrange total cost (TC), Marginal Cost (MC), Average Cost (AC), Average Fixed Cost (AFC) in increasing order when Q = 2.
(a) AFC 
(b) TC 
(c) MC 
(d) AC
