The total cost of a firm is C=1/3×3 – 6×2 + 40x =15. Find the equilibrium output if price is fixed at Rs. 20 per unit.

Introduction This question is related to microeconomic concepts where cost and revenue functions are used to determine equilibrium output. In simple words, equilibrium output is the number of units where a firm achieves balance — i.e., when marginal cost (MC) equals marginal revenue (MR). If price is fixed, then marginal revenue is also fixed. In […]

The profits (in Rs. Lakhs) earned by 100 companies during the 1987-88 are shown below. Compute (a) Mean, (B) Variance, and (c) Standard deviation by using items and their squares.

Introduction Understanding how to calculate mean, variance, and standard deviation is fundamental in statistics. These measures help summarize the distribution of data in terms of central tendency and spread. In this question, we are given a frequency distribution (presumably in tabular form) for the profits earned by 100 companies during 1987–88 and we have to

A stereo manufacturer determines that in order to sell x units of a new stereo, the price per unit, in rupees, must be p(x) = 1000 – x . The manufacturer also determines that the total cost of producing x units is given by C(x) = 3000+ 20x. a) Find the total revenue R(x). b) Find the total profit P(x). c) How many units must the manufacturer produce and sell in order to maximise profit? d) What is the maximum profit? e) What price per unit must be charged in order to make this maximum profit?

Introduction This question is based on concepts from business mathematics involving revenue, cost, and profit functions. We are given a pricing function and a cost function. We need to calculate the total revenue, total profit, and then determine the optimal number of units to maximize profit along with the corresponding maximum profit and the price

A shopkeeper charges Rs. 25 per item for buying 20 or less items. He gives some rebate if items bought are more. If the items bought are 50 or less, then a rebate of Re. 1 per item and for purchase of more than 50 items, rebate of Rs. 2 per item. Find the cost function. What are the points at which this is not continuous?

Introduction In business mathematics, cost functions help us understand how pricing changes based on the number of units sold or purchased. In this question, we are given a tiered pricing scheme by a shopkeeper. The task is to derive a cost function that accurately models the total cost based on the quantity of items purchased
