(a) Represent the information on a pie chart.
(b) What percentage of his income is spent on transportation?
Answer Details
Total monthly income
\[4500+3000+2500+2000+5000+3000=N20\,000\]
(a) Pie chart
The angle for each sector is:
\[\text{Sector angle}=\frac{\text{amount spent}}{20\,000}\times360^\circ\]
| Item | Amount (₦) | Sector angle |
|---|---|---|
| Food | 4,500 | \(\frac{4500}{20000}\times360^\circ=81^\circ\) |
| House Rent | 3,000 | \(54^\circ\) |
| Provisions | 2,500 | \(45^\circ\) |
| Electricity | 2,000 | \(36^\circ\) |
| Transportation | 5,000 | \(90^\circ\) |
| Others | 3,000 | \(54^\circ\) |
| Total | 20,000 | \(360^\circ\) |
The required pie chart is:
(b)
\[\text{Percentage spent on transportation}=\frac{5000}{20000}\times100\%=25\%\]
Therefore, 25% of his income is spent on transportation.
