Answer:
C. 1 billion and 3 billion
Explanation:
We know from the national accounts identity that in a closed-economy like Yokovia GDP is equal to:
GDP = C + I + G
Where:
From the question, we have obtained the information that GDP is $20 billion, Consumption is $15 billion, and Investment is $2 billion. We plug those amounts into the identity:
GDP = C + I + G
$20b = $15b + $2Bb + G
After laying out this information, we can be certain that G (Government spending or Government purchases) equals $3 billion, because otherwise, the equation would not hold true. Thus:
$20b = $15b + $2b + $3b
As for the value of National Saving, we know that National Saving is equal to:
Nationa Salving = Government Purchases - Taxes
= $3b - $2b
= $1b
