What is the relation between NDP_MP and NDP_FC ?

NDP_mp - when depreciation is substrated from GDP_mp we get NDP_mp. Thus NDP_mp= GDP_mp- Depreciation. 

In other words, NDP_mp is the market value of final goods and services produced within the domestic territory of a country during a year, exclusive of depreciation.

NDP_FC - When depreciation is subtracted from GDP_FC we get NDP_FC

Thus NDP_FC = GDP_FC - Depreciation

In other words NDP_FC is the value of final goods and services produced within the domestic territory of a country at factor cost, exclusive of depreciation. It is the sum total of factor incomes generated within the domestic territory and is also known as Domestic Income.
