Private final consumption expenditure = 1100 crore.

Gross domestic fixed capital formation = 1000 crore.

Government final consumption expenditure = 900 crore.

Net imports = 75 crore.

GDP_MP = Private final consumption expenditure + Government final consumption expenditure + Gross domestic capital formation + Net exports

GDP_MP = Private final consumption expenditure + Government final consumption expenditure + (Gross domestic fixed capital formation + Change in stocks) + Net exports

2995 crore = 1100 crore + 900 crore + (1000 crore + Change in stocks) + (-75 crore)

2995 crore = 2000 crore + 1000 crore + Change in stocks - 75 crore

2995 crore = 2925 crore + Change in stocks

Change in stocks = 2995 crore - 2925 crore
