Dear Student
a) Revenue Deficit = (Tax Revenue + Non Tax Revenue) - Revenue expenditure 
Revenue Deficit = 18000 -8000 -3000 = 7000

b) Fiscal Deficit = Total Expenditure - Total Receipts
Fiscal Deficit = (18000 + 2000 + 40000) - (5000+5000+ 3000 + 8000+ 3000 )
Fiscal Deficit = 36000

c) Primary Deficit = Fiscal Deficit - Interest Payments
Primary Deficit = 36000 - 2000
Primary Deficit = 34000
