Answer

₦425 billion
Disposable Personal Income is obtained by first calculating Personal Income (National Income minus corporate profit tax, undistributed corporate profits, and social security contributions, plus transfer payments) and then subtracting personal direct taxes. Here, Personal Income=500403020+50=460 billion\text{Personal Income} = 500 - 40 - 30 - 20 + 50 = 460\text{ billion}, and Disposable Personal Income=46035=425 billion\text{Disposable Personal Income} = 460 - 35 = 425\text{ billion}.

Step-by-Step Solution

1
Calculate Personal Income (PI) from National Income (NI)
PI=500403020+50=460 billion\text{PI} = 500 - 40 - 30 - 20 + 50 = 460\text{ billion}
Corporate profit taxes, undistributed corporate profits, and social security contributions are earned income not received by individuals, whereas transfer payments are income received without corresponding current production.
2
Calculate Disposable Personal Income (DPI) from Personal Income (PI)
DPI=46035=425 billion\text{DPI} = 460 - 35 = 425\text{ billion}
Disposable Personal Income is the net income available to households after deducting personal direct taxes.
