interesting n effective teaching
thanks Arpita, 11/10 for your efforts, I have watched your all lessons of geography and I don't have enough words to thank. you for simplifying geography ncerts, but in this lesson of economics I think you have unnecessarily complicated things, it's very easy to understand aggregate for some who is reading 12th ncert One suggestion - please don't over complicated things, please don't take it negatively, I am a fan of your courses😊

mam ..how many days it(complete book) take?

Point C- Income Method- measuring sum total of all factor payments . Equal flows at Point A and C .
