I was trying to calculate the GDP using the income method, but I don't know what to do with the inputs purchased etc.

Question

Here are the data:

Agriculture:
Total sales --- $50
Capital goods Purchased --- $40
Manufacturing inputs --- $30
Wages --- $20
Operating Surplus --- $10

Manufacturing:
Sales of Capital goods --- $55
Sales of other manufactures --- $155
Capital goods purchases --- $35
Agricultural inputs purchased --- $45
Wages --- $65
Operating surplus --- $25

Could someone please help me out by calculating the GDP using any method? I have tried using the income method and the production method but the answer wouldn't match.

Thank you.
