GDP = Consumption + Investment + Government purchases
=> $900 million = $375 million + Investment + $250 million
=> Investment = $900 million - $375 million - $250 million
=> Investment = $275 million
----------------------
Y = C + I + G
=> I = Y - C - G
National Saving (S) = Y - C - G
= I
=$275 million
-------------------------
Private Saving = Y - C - T
= $900 million - $375 million - $325 million
= $200 million
----------------------
Public Saving = T - G
= $325 million - $250 million
= $75 million
---------------------
Based on your calculation, the government is running a budget surplus
