Answer: (a) $35,000 and $15,000
(b) $50,000
(c) $50,000
Explanation:
Given that,
OrangeInc sells some of its oranges to the public and making = $10,000
Remaining oranges sells to JuiceInc, making = $25,000
Total revenue of JuiceInc = $40,000
(a) Value added by OrangeInc = $10,000 + $25,000
                          = $35,000
Value added by JuiceInc = Total revenue - Oranges purchased from OrangeInc
                     = $40,000 - $25,000
                     = $15,000
(b) GDP using the Product Approach:
 GDP = Value added by OrangeInc + Value added by JuiceInc
      = $35,000 + $15,000
      = $50,000
(c) GDP using the Expenditure Approach:
In our case, the final consumers of oranges are households. Households purchases oranges worth of $10,000 from OrangeInc and juice worth of $40,000 from JuiceInc.
Therefore,
GDP = $10,000 + $40,000
    = $50,000
