Total budget = N100,000,000
Portion of pie chart covered in degree = 360
Expenditure on manufacturing = x/N100,000,000 × 3600 = 360
3600x = 360 × N100,000,000
x = 360×N100,000,000/3600
x=N10,000,000
Therefore, the budget allocated to Manufacturing is N10,000,000
Total budget = N100,000,000
Portion of pie chart covered in degree = 720
Expenditure on Agriculture = x/N100,000,000 × 3600 = 720
3600x = 720 × N100,000,000
x = 720 × N100,000,000/3600
x = N20,000,000
Therefore, the budget allocated to Agriculture is N20,000,000
Ratio of expenditure on Manufacturing to Agriculture;
Ratio = 10,000,000:20,000,000
=1:2
