Answer the question please

Dear student,

NVA_{FC =} Value of output - Intermediate consumption - Depreciation - Net Indirect Taxes
NVA_FC =  (Sales + Change in stock ) ​- Intermediate consumption - Depreciation - (Indirect Taxes - Subsidies)
NVA_FC =  (150 + (-10)) - 90 - 20 - (0 - 10)
NVA_FC =  140 - 110 + 10
NVA_FC =  40 (Rs in crore)

Note:  Exports are not included as sales are given and sales includes both domestic sales as well as exports.
Import of raw material are not included separately as intermediate cost includes domestic intermediate purchases as well as import of raw materials.
