Sales = Units of Output sold x Price Per Unit of Output
=1000 x 30 = ?
30000 crore Value of Output = Sales + Change in Stock = 30000 + (3000 - 2000) = Rs 31000 crore
Hence, GV{{A}{PC}} = Value of Output - Intermediate Cost - Net Indirect Taxes (Excise + Sales Tax) = 31000 -12000 - (2500 + 3500)
GV{{A}{PC}} = Rs 13000 crore
