CEVAP:

General price level theoretically indicates the weighted average of all goods and services in an economy within a period of time. General price level is specified
with an index. For this purpose, firstly any year’s price level is taken as a basis and indicated as 100. Then, subsequent years’ levels are calculated according to
this 100 value. Thus, price levels in various years are explained in terms of increases and decreases according to base year’s price level. Base year is not selected randomly, rather various economic, politic and social events are considered in selection.
