The table below shows how a company’s sales manager spent his 1995 annual salary.
| Food | 30% |
| Rent | 18% |
| Car Maintenance | 25% |
| Savings | 12% |
| Taxes | 5% |
| Others | 10% |
(a) Represent this information on a pie chart.
(b) Find his savings at the end of the year if his annual salary was N60,000.00.
Explanation
Angle of sector:
(Food = frac{30}{100} times 360° = 108°)
(Rent = frac{18}{100} times 360° = 64.8°)
(text{Car Maintenance} = frac{25}{100} times 360° = 90°)
(Savings = frac{12}{100} times 360° = 43.2°)
(Taxes = frac{5}{100} times 360° = 18°)
(Others = frac{10}{100} times 360° = 36°)
(a)
(b) Annual Salary = N60,000.00
(therefore Savings = N(frac{12}{100} times 60,000) = N7,200)
