Answer (a)
In year 1946, Government expenditure = 55.2 and Revenue = 39.3. As we can see than Government expenditure > Revenue. This means that have borrowed as Government expenditure > Revenue. This borrowed amount will increase debt. So in 1946 they will incur additional debt = 55.2 - 39.3 = 15.9
Thus, At the end of 1946, Debt = Debt at end of year 1945 + Additional debt in year 1946 = 350 + 15.9 = 365.9
In year 1947, Government expenditure = 54.5 and Revenue = 38.5. As we can see than Government expenditure > Revenue. This means that have borrowed as Government expenditure > Revenue. This borrowed amount will increase debt. So in 1947 they will incur additional debt = 55.5 - 38.5 = 16
Thus, At the end of 1947, Debt = Debt at end of year 1946 + Additional debt in year 1947 = 365.9 + 16 = 381.9
Hence, At the end of 1947, Debt level = $381.9
