Law of variable proportion
Example taken in video is wrong .it is TP, AP and MP and in video sir taken TR in place of TP ,AR in place of AR and so on.
Dear student Example taken in the video is not wrong. In economics the words product and revenue is often interchangeable. As the word revenue = no of units(variable) * price (which is assumed to be constant) it has overall no effect on the respective graph. Thank you
