Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A profit-maximising monopolist in two separate markets will
A
Adjust his sales in the two markets so that his MR in each market just equals his aggregate marginal cost
B
Always charge a higher price in the market where he sells more
C
Always charge a higher price in the market where he sells less
D
Charge the same price in both markets
Explanation: 

Detailed explanation-1: -In a monopolistic market, a firm maximizes its total profit by equating marginal cost to marginal revenue and solving for the price of one product and the quantity it must produce.

Detailed explanation-2: -We say that in a monopoly, profit is maximized when MR=MC, just like in a competitive market, when MR = Price = MC. You will remember that in a competitive market, the demand curve is flat. Its slope is zero. So, the derivative of this curve, which is the MR curve, also has a slope of zero (two times zero = zero).

Detailed explanation-3: -The monopolist’s profit maximizing level of output is found by equating its marginal revenue with its marginal cost, which is the same profit maximizing condition that a perfectly competitive firm uses to determine its equilibrium level of output.
