Question number 7 please

Dear Student,

As we know that-

$$\begin{gathered} \mathrm{Value} \mathrm{added}= \mathrm{Value} \mathrm{of} \mathrm{output}-\mathrm{Intermediate} \mathrm{consumption} (\mathrm{cost} \mathrm{of} \mathrm{non}-\mathrm{durable} \mathrm{goods} \mathrm{purchased} \mathrm{by} \mathrm{firm}) \\ \mathrm{and}, \mathrm{Value} \mathrm{of} \mathrm{output}=\mathrm{Changes} \mathrm{in} \mathrm{stock} \mathrm{of} \mathrm{the} \mathrm{firm}+(\mathrm{number} \mathrm{of} \mathrm{units} \mathrm{manufactured}\times \mathrm{price})= \mathrm{Rs} 250+(200\times 5) \\ \mathrm{Value} \mathrm{of} \mathrm{output}= \mathrm{Rs} 1250 \\ \mathrm{Value} \mathrm{added} \left(\mathrm{given}\right)= \mathrm{Rs} 570 \\ \mathrm{therefore}, \\ \mathrm{Value} \mathrm{added}=\mathrm{Value} \mathrm{of} \mathrm{output}-\mathrm{Intermediate} \mathrm{consumption} \\ 570=1250-\mathrm{Intermediate} \mathrm{consumption} \\ \mathrm{Intermediate} \mathrm{consumption}=1250-570=\mathrm{Rs} 680 \end{gathered}$$

Hence, the cost of non-durable good purchased by the firm is Rs 680
