Answer:
Gross investment will be equal to $175 billion
Explanation:
We have given nation's capital stock at the start = $200 billion
And capital stock at the end = $350 billion
Consumption of private fixed capital in the year = $25 billion
We have to find the gross investment
Gross investment is equal to
Gross investment = Capital stock at the end of the year + consumption of private fixed capital - Capital stock at the starting of the year
= $350+$25-$200 = $175
So gross investment will be equal to $175 billion
