How many units should Mrs. Nidhi produce daily?

### Question Asked by a Student from EXXAMM.com Team

Q 2264167955.     Mrs. Nidhi manufactures and sells a single product at a fixed price in a niche market. The selling price of each unit is Rs. 30. On the other hand, the cost, in rupees, of producing x units is 240 + bx + cx^2 , where b and c are some constants. Mrs. Nidhi noticed that doubling the daily production from 20 to 40 units increases the daily production cost by 66 %. However, an increase in daily production from 40 to 60 units results in an increase of only 50% in the daily production cost. Assume that demand is unlimited and that Mrs. Nidhi can sell as much as he can produce. His objective is to maximize the profit.
