As a result of the above transactions and using the national income formula, the national income A. rises by $175,000.
The formula for calculating the national income here is Rent + Wages + Interest + Profit + Mixed-Income.

Consultant fee (mixed income) = $8,000
Occupational pension (mixed income) = $9,000

$0+ -$30,000 -$12,000 + $0 + $200,000 + $8,000 + $9,000
= -$42,000 + $217,000
National income = $175,000
