Answer:

D) falls by $40 billion.

Explanation:

Since the government has raised the lump sum taxes on income to $100billion and the marginal propensity to consumer is 0.6

Therefore to find the consumption level

$100,000,000,000.00 * 0.6 = $60,000,000,000.00

Hence, the investment level too falls by $40,000,000,000.00

In other words, Private consumption falls by 60 billions. Thus, private saving falls by 40 billions.
