Q1
Unit I
(a)Draw a percentage bar diagram for the following data :[10]
Answer
The figures given in the question
| Expenditure | Company A Rs. | Company B Rs. |
|---|---|---|
| Materials | 3,00,000 | 4,00,000 |
| Wages | 50,000 | 60,000 |
| Power | 1,00,000 | 1,30,000 |
| Maintenance | 20,000 | 30,000 |
| Total | 4,70,000 | 6,20,000 |
For full marks, cover: what a percentage bar diagram shows and why it suits two companies of different size; each item as a percentage of its company's total; the cumulative percentages that mark the divisions; how the two bars are drawn and shaded; and what the diagram shows.
Why a percentage bar diagram
Company A spends Rs 4,70,000 and Company B Rs 6,20,000. Their totals differ, so a comparison in rupees would mainly show that B is larger. A percentage bar diagram draws each company's total as a bar of the same height, 100 per cent. Each bar is divided in proportion to the share of each item, so the cost structures of the two companies can be compared directly.
Step 1: Company A (total Rs 4,70,000)
| Item | Expenditure | Percentage = Expenditure/4,70,000 × 100 | Cumulative expenditure | Cumulative percentage = Cumulative expenditure/4,70,000 × 100 |
|---|---|---|---|---|
| Materials | 3,00,000 | 63.83 | 3,00,000 | 63.83 |
| Wages | 50,000 | 10.64 | 3,50,000 | 74.47 |
| Power | 1,00,000 | 21.28 | 4,50,000 | 95.74 |
| Maintenance | 20,000 | 4.26 | 4,70,000 | 100.00 |
| Total | 4,70,000 | 100.01 |
Step 2: Company B (total Rs 6,20,000)
| Item | Expenditure | Percentage = Expenditure/6,20,000 × 100 | Cumulative expenditure | Cumulative percentage = Cumulative expenditure/6,20,000 × 100 |
|---|---|---|---|---|
| Materials | 4,00,000 | 64.52 | 4,00,000 | 64.52 |
| Wages | 60,000 | 9.68 | 4,60,000 | 74.19 |
| Power | 1,30,000 | 20.97 | 5,90,000 | 95.16 |
| Maintenance | 30,000 | 4.84 | 6,20,000 | 100.00 |
| Total | 6,20,000 | 100.01 |
The percentages are rounded to two places, so they add to 100.01. The cumulative percentages, worked from the amounts, end exactly at 100.
Step 3: drawing the diagram
- Draw the Y axis from 0 to 100 per cent, with 1 cm for 10 per cent.
- Draw two bars of equal width, one for Company A and one for Company B, each 100 per cent high, with a gap between them.
- Divide Company A's bar from the base at 63.83, 74.47 and 95.74 per cent.
- Divide Company B's bar from the base at 64.52, 74.19 and 95.16 per cent.
- Shade each item the same way in both bars (for example, materials dark and maintenance light), and give a key.
- Write the title "Cost structure of Companies A and B (percentage of total expenditure)".
What the diagram shows
The two bars look almost alike. Materials take nearly two-thirds of the total in both companies (63.83 and 64.52 per cent). Power is the next largest item in both, at about a fifth. Company A spends a slightly larger share on wages and power, and Company B on materials and maintenance. In proportion, the two companies spend in very much the same way, though B spends more in rupees.
Conclusion. In the percentage bar diagram both companies' bars are 100 per cent high, divided at the cumulative percentages above. It shows that materials take about 64 per cent of the expenditure of each company, so their cost structures are very similar.
