1. Production of a firm is given by the Cobb Douglas Function Q= 6K 0.6 L0.3, Find out productions for the following combinations (K=1, 1=2) and (K=2, L=4) where K and L stand for capital and Labor. What is the return to scale exhibited by the firm? (2+1)
2. The following combinations of K and L produce 25 units of product X. Graphically represent the data in the form of an isoquant. Identify the regions outside economic region of production.
3. If the unit costs of capital and labor are U$ 10 and US 20 respectively and the total cost is US 200, what is the equation of the corresponding isocost? What is the cost minimizing point of operation if the isoquant is as given in sub-question (b)? Graphically represent the above situation.
