Answer -
(i) TC is divided into two parts TFC and TVC such that TC = TFC + TVC.
(ii) TFC is the overhead cost and it remains constant or fixed whatever be the level of output. TFC curve is a horizontal line parallel to the x-axis.
(iii) TVC is cost due to increased use of variable factors like raw material, labour, etc. TVC is inverse S-shaped starting from the origin due to law of variable proportion.
(iv) TC is aggregate of TFC and TVC. TC curve is inverse S-shaped starting from the level of fixed cost. The reason behind it shape is the law of variable proportion.
