Question

A company's total annual expenditure of ₹20,00,000 is distributed under the following heads. Draw a pie diagram showing the percentage and angle for each head.

| Head | Raw Materials | Wages | Rent | Marketing | Miscellaneous |
|---|---|---|---|---|---|
| Amount (₹) | 8,00,000 | 6,00,000 | 2,00,000 | 3,00,000 | 1,00,000 |

Accepted Answer

**Step 1 — Compute each head's percentage of the ₹20,00,000 total.**
$$	ext{Raw Materials} = \dfrac{800000}{2000000}	imes100 = 40\%$$
$$	ext{Wages} = \dfrac{600000}{2000000}	imes100 = 30\%$$
$$	ext{Rent} = \dfrac{200000}{2000000}	imes100 = 10\%$$
$$	ext{Marketing} = \dfrac{300000}{2000000}	imes100 = 15\%$$
$$	ext{Miscellaneous} = \dfrac{100000}{2000000}	imes100 = 5\%$$
Check: $40+30+10+15+5=100\%$ ✓.

**Step 2 — Convert each percentage to a sector angle** (since $360°$ corresponds to $100\%$, multiply each percentage by $3.6°$).
$$40	imes3.6=144°,\quad 30	imes3.6=108°,\quad 10	imes3.6=36°,\quad 15	imes3.6=54°,\quad 5	imes3.6=18°$$
Check: $144+108+36+54+18=360°$ ✓.

**Step 3 — Draw the pie diagram.**
