when TR is maximum then MR is also maximum ?give reason for your answer
When TR is maximum, MR is not at its maximum. Rather, MR is zero when TR reaches its maximum. This is due to the fact that when MR is zero, it implies that there is no addition to the total revenue. That is, TR becomes constant at this point. Also, after this point, as MR becomes negative with the selling of each additional unit of output, TR will decline. Thus, at the point where MR is equal to zero, we say, TR will be at its maximum.
